GRIFFON VULTURE FEEDING YOUNG—PUERTA DE PALOMAS, April 10, 1910.
GRIFFON VULTURE FEEDING YOUNG—PUERTA DE PALOMAS, April 10, 1910.

These eyries were situate on three great outstanding stacks of rock, and during the scramble we came face to face with a pair of eagle-owls solemnly dreaming away the hours in the recesses of a cavern, though no sign of a nest was discovered. The caves were shared by crag-martins, whose swallow-like nests were fixed under the roof, usually just beyond reach. Their eggs are white, flecked with grey. On May 18 we obtained here a nest of the rock-thrush with five beautiful greenish-blue eggs. It was built in a cranny of the crags.

This year (1910) found us once more in the Puerta de Palomas, the date April 8. On rounding the Sierra de las Cabras, as L. was already far up the hillside, I rode forward intending to ascend at the north end and work back, thus meeting in centre. A succession of mischances, however, upset that plan. A small clump of ilex clung to the steep above the point whereat I had left the horses, and in traversing this, I walked right into a calf concealed beneath a lentiscus. Knowing that this might involve trouble should its half-wild mother be within hearing, I gently retreated, but, hard by, stumbled on a second calf, even smaller, in another bush. No. 1 meanwhile had gained its legs and bleated softly. There followed a crash among the bush above, and as fierce-looking a wild beast as ever I saw (and I have seen some) came hurtling down those rugged rocks at amazing speed. On seeing me (luckily some little distance from her own offspring) the infuriated mother pulled up, full-face—a pretty picture, but rather menacing, especially as she kept up a muttered bellowing, horribly eloquent. I had sidled alongside a tree; but Paco, who carried my gun, with the reckless spirit begotten of the bull-fight, boldly addressed the enemy in opprobrious terms. The only result was that she came still nearer, and I swung to a lower branch. Paco, nothing daunted, now tried stones (in addition to expletives), and it was, to me at least, a relief when that cow at length retired. The half-wild savage may easily be more dangerous than the truly wild. The former have lost some of their pristine respect for man, and of course one has less means of defence.

This incident over, we commenced the climb. The rock-stack rose vertically above us, but we diverged to the right as affording an easier route. On reaching the desired level, however, I found it impossible to make good that interval on our left—a smooth rock-face devoid of handhold, and too upright to traverse, forbade all lateral movement. Up we went another twenty yards, then another; but always to find that slithery rock-face mocking our efforts to outflank it. We were now well above the rock-stack overlooking the eyries, and I could see two griffons brooding, another feeding a poult close by. But between us was a great gulf fixed, and that gulf stopped us. The obvious alternative was to descend and try again from a fresh point. But here a new difficulty faced us: we could not descend. We had come up by following a series of vertical fissures, or “chimnies,” none too easy, since every crevice sheltered some vicious vegetation, each more spikey and thorny than the last. Still from below one can always select a handhold somewhere, and then defy the thorn; whereas on looking backwards, nothing is visible but a vanishing outline of rock and gorse, porcupine broom, or palmetto—beyond is vacant space, and a sheer drop at that. In a word, we could neither descend nor move laterally. It was humiliating—even more so than the antecedent incident with a COW!

One resource remained—to climb on to the top; and even in that direction a single bad rock might cut off escape. No such crowning catastrophe befell, but it was tooth-and-claw work, every yard of it, and the vertical height could not have been less than 1000 feet.

While thus “clawing up” I recollect passing a perfect glory in orchids—great twin purple blooms, golden-tipped and quite amorphous in outline. They grew just beyond my reach. Curious recumbent ferns clung to the rocks; anemones and violet-like bouquets peered from each cranny.

Meanwhile L., approaching from the other side, had examined the rock-stacks and succeeded in attaining one main objective—the nest of the eagle-owl. This was in a rock-cavern, close by that of ’83, easy of access—indeed the great owl flew out in his face as he passed below. The cave (four feet high by two wide) was at the foot of a vertical limestone cliff, its floor level with a goat-track that skirted the crag, and fully exposed to view; there was no nest nor any debris. Two young owls in white down, with one egg actually “chipping,” lay on the bare earth.

 

One of the griffon’s nests still contained (on April 8) a fresh egg, which is now in the writer’s collection as a memorial of that day. We had secured all we had expected in the Puerta de Palomas—and something more besides.

CHAPTER XXXVII

A SPANISH SYSTEM OF FOWLING

THE “CABRESTO” OR STALKING-HORSE

SPAIN is a land of flocks and herds, of breeders and graziers. At the head of the scale stands the fighting-bull, monarch of the richest vegas; at the opposite extreme come the shaggy little ponies and brood-mares that eke out a feral and precarious subsistence in the wildest regions. Throughout the marismas hardy beasts with wild-bred progeny on which no human hand has ever laid, abound, grazing knee-deep in watery wildernesses where tasteless reed or wiry spear-grass afford a bare subsistence.

There they live, splashing in the shadows, heads half-immersed as they pull up subaquatic herbage; on the back of one rides perched a snow-white egret, on another a couple of magpies, preying on ticks or warbles, while all around swim wildfowl that scarce deign to move aside.

No fowler could view such a scene without perceiving that approach to the wildfowl might be effected under cover of these unsuspected ponies. The earliest aucipial mind probably realised the advantage offered, and the system has been practised in Spain from time immemorial.

The method is simple. The ponies (termed, when trained, cabrestos, or “decoys”) seem by intuition to realise what is required. By a cord attached to the headstall, the fowler, crouching behind the shoulder, directs his pony’s course towards the unconscious fowl. At intervals, still further to disarm suspicion, feigned halts are made as though to simulate grazing. Before closing in, the nose-cord is made fast to the near fore-knee, thus holding the pony’s head well down. Presently the ducks are within half gunshot, and we amateurs (whose doubled backs ache excruciatingly from a constrained position maintained for half an hour) pray each moment for relief and the signal to fire. No! Our fowler-friends shoot for a livelihood, and continue, with marvellous skill and patience, so to manœuvre their beasts that the utmost possible target shall finally be presented to the broadside. There is no hurry—nor time nor aching vertebræ with them count one centimo. (See photo at p. 90.)

Should it be necessary to change course, that operation is effected by wheeling the pony stern-on to the fowl, the fowler meanwhile crouching low under his muzzle: critical moments ensue during which the expert has no cover but the pony’s breadth—instead of his length—to shield him from detection by hundreds of the keenest eyes on earth. But it is remarkable how little notice is taken of what is necessarily in full view provided that the exposed objects are beneath the covering animal. Once let a human head or a gun-barrel appear above its outline and the spell is broken. But otherwise—say during those interludes of feigned “grazing”—the suffering fowlers can straighten their backs by squatting down (in the water!) and thus enjoy at closest quarters a spectacle of wild creatures that is impossible to attain by any other means yet discovered. Though the fowlers are now fully visible, framed, as it were, beneath the cabresto’s belly and between his legs, no notice will be taken or any alarm created so long as the pony’s skylines remain unadorned with human appendages. There, within a score of yards, you sit face to face with ducks by the hundred, feeding, splashing, preening—all utterly unconcerned! Those of our readers who are most familiar with wildfowl will best realise how incredible such a statement must read. Ordinarily, the slightest visible movement—the mere glint of a gun-barrel though half masked by cover—suffices to shift every duck at one hundred yards and more. Here they ignore objects practically exposed and close at hand. Apparently the habitual companionship day by day of water-bred ponies has annihilated in their minds all sense of danger arising from such a quarter.

The Spanish professionals (using large but antiquated muzzle-loaders) work singly, each man behind his own pony; or should two or more join forces for a broadside, there still remains but one man behind each animal. These men are reputed to have made extraordinary shots; and having viewed their infinite patience, we can well believe such records. To place two guns behind one cabresto-pony, that is, an amateur as well as the professional, is a distinct handicap. We have done it ourselves, and accepted the handicap merely to see the system in operation; yet by using more powerful weapons have probably killed as many fowl at one shot as even the fabled totals of our friends.

Obviously no comparison can be, or is, suggested as between two totally different performances. It has been solely for the purpose of learning the system, and also of enjoying unequalled views of wildfowl close at hand, that we have occasionally put in a day with the cabresto-ponies, and here annex a few records of shots made by this means, taken at random from our diaries.

January 1, 1898.—Fired three broadsides with two guns, a double 8-and a single 4-bore; in the second case the fowl had just been badly scared by a kite. Results:—

(1)59 wigeon, 3 teal62
(2)30 " 3 "33
(3)60 " 1 " 4 pintail, 4 shoveler69
 Total164

January 31, 1905.—In three shots at wigeon, the first being half spoilt by a big black-backed gull, the authors (two guns) gathered:—

27 + 51 + 48 = 126 wigeon.

December 29, 1893.—Santolalla (2 guns), 78 teal, besides some coots, at a single shot.

January 1894.—Laguna Dulce; three cabrestos with Spanish fowlers, and two amateurs with big breech-loaders (a broadside of 5 barrels):—

198 teal (including about a dozen wigeon).

A shot made in January 1894 seems worth recording merely in respect of the numbers killed by only some seven ounces of lead. An islet actually carpeted with teal was our target, and two 12-bores, aided by an ancient Spanish muzzle-loader (about 10-bore), realised fifty head, to wit, forty-nine teal and one mallard-drake.

Geese will rarely admit of approach to the close quarters necessary for effective work; yet just on those rare exceptional occasions we have secured (using heavy shoulder-guns) from six to a dozen greylags in a day, once or twice more than this—five at a shot being the maximum.

The Stanchion-Gun in Spain

In contrast with the success of the cabresto system, the stancheon-gun proved a failure. So admirably adapted for punt-gunning appeared those great shallow marismas, that in 1888 we sent out the entire outfit and artillery for wildfowling afloat—a 22-foot double-handed gunning-punt and an 80-lb. gun to throw 16 oz. of shot.

The little craft reached the Guadalquivir in September, but unforeseen difficulties arose. The Spanish custom-house took alarm. True, the smart little gun-boat was an entire novelty—even in the Millwall docks she had created surprise; here she was incomprehensible. No such vessel had ever floated on Spanish waters, and the official mind needed time to consider. That oracle, after weeks of cogitation, ordered the removal of the suspicious craft from the obscure port of Bonanza to the fuller light that plays on the custom-house at Seville. There, after more weeks of delay, it was decided that the white-painted six-foot barrel was “an arm of war,” that “the combination of boat and gun savoured of the mechanism of war,” and, finally, that “the boat could not be permitted to pass the customs until it had been registered at the Admiralty.” Thus our Boadicea joined the Imperial Navy of Spain.

Seven months elapsed whilst these difficulties were in process of solution, and ere they were smoothed away (as difficulties in Spain, or elsewhere, do dissolve under prudent treatment), and the Boadicea set free to navigate the marismas, the season had passed and the migrant fowl had returned to the north.

The following autumn, however, it at once became apparent that the venture was a failure. No wildfowl would tolerate her presence within half-a-mile. No sooner had her low snake-like form crept clear of fringing covert than the broad lucio in front was in seething tumult, every duck within sight had sprung on wing. Naturally we tried every known plan, but all in vain. A system that is effective on the harassed and hard-shot estuaries of England utterly broke down on the desolate marismas of Spain. The apparent explanation is that whereas fowl at home are accustomed to see passing craft of many kinds, and perhaps mistake the low-lying gunboat for a larger vessel far away; here no craft of any sort navigate the marisma, or should the box-shape cajones of native gunners be so classed, they are at once recognised as wholly and solely hostile.[63]

One plan remained by which the big gun might be brought to bear upon the larger bodies of fowl: concealing the boat among sedges at some point where ducks had been observed to assemble within reach of such covert. That, however, to begin with, was most uncertain—the only certainty was that enormous drafts on patience would be required; and, after all, it forms no part of the system of wildfowling afloat and lacks the joys and glories of that pursuit.

Wild Swans in Spain

Since meeting with four hoopers in February 1891, as recorded in Wild Spain, we had neither seen nor heard of wild swans in Southern Spain till February of the present year, 1910, when H.R.H. the Duke of Orleans kindly informed us that he had succeeded in shooting one of a pair met with in his marismas of Villamanrique. It proved to be an adult male of Bewick’s swan—the first occurrence of that species that has been recorded in Spain.

CHAPTER XXXVIII

THE “CORROS,” OR MASSING OF WILDFOWL IN SPRING FOR THEIR NORTHERN MIGRATION

THE withdrawal of the wildfowl at the vernal equinox affords an unequalled scenic display. It forms, moreover, one of those rare revelations of her inner working that Nature but seldom allows to man. Her operations, as a rule, are essentially secretive. A little may be revealed, the bulk must be inferred. Here, for once, a vast revolution is performed in open daylight, coram populo—that is, if the authors and a handful of Spanish fowlers be accepted as representative, since no other witness is present at these scenes enacted in remote watery wilderness.

Up to mid-February the daily life of the marisma continues as already described. From that date a new movement becomes perceptible—the seasonal redistribution. Daily there withdraw northward bands and detachments counting into thousands apiece. But no vacancy occurs since their places are simultaneously filled by corresponding arrivals from beyond the Mediterranean.

It is at this precise epoch that there occurs the phenomenon of which we have spoken.

Towards the close of February, dependent on the moon, a marked climatic change takes place. A period of sudden heat usually sets in—a sequence of warm sunny days, breathless, and at noontide almost suffocating. But each afternoon with flowing tide there arises from the sea a S. W. breeze, gentle at first and uncertain but gaining strength with the rising flood.

Already, shortly before this change, the duck-tribes had partially relaxed their full mid-winter activities—owing to abundant spring growths of food-plants, had become more sedentary; if not sluggish, at least reluctant to move. After the brief morning-flight not a wing stirred. But now, scan the mirror-like surface of some great lucio and you will recognise a new movement distinct and dissimilar from regular hibernal habit. There float within sight (and the same is happening at a score of places beyond sight) not only the usual loose flotillas, but three, four, or five concrete assemblages of densely massed fowl whose appearance the slightest scrutiny will differentiate from the others. These are not sitting quiescent. The binoculars disclose a scene of perpetual motion, well-nigh of riot—one might be regarding a feathered faction-fight. Hundreds of units fight, splash, and chase, or throw up water with beating wings till surf and spray half conceals the seething crowd. That flicker of pinions and flying foam are, moreover, accompanied by a chorus of myriad notes—a babel of twirling sound blended in rising and falling cadences, comparable only to the distant roar of some mighty city. A more singular spectacle we have not encountered.

Inquiry from one’s companion elicits the reply that these assemblages are hechando corros para irse (literally, “forming choruses preparatory to departure”)—an expression which conveyed no more significance to us than it can to the reader.[64] We decided to return at daybreak to see this thing through, and after watching the phenomenon a score of times can now explain it.

During the morning hours there are established focal points whereat assemble those units already affected by the emigrant furor. These (at first, perhaps, but a score or two) rapidly increase in numbers till each focus becomes the nucleus of a corro. The seasonal infection spreads, and as its influence impregnates the surrounding masses, these, singly or in scores or hundreds as the passion seizes them, hasten to join one or other of the mobilising army-corps. Within an hour or two the insignificant original nucleus has developed into a vast host all in a ferment of agitation, and being constantly reinforced by buzzing swarms of recruits from without.

All this procedure, remember, has been taking place during the blazing noontide heat. Now the hour is 2 P.M., and the first gentle breath of the daily sea-breeze—the viento de la mar—is becoming perceptible. This breeze springs from the S. W., and let us here admit that, being fowlers as well as naturalists, our observance of the phenomenon has usually been carried out upon a lucio which happens to terminate towards the N. E. in a long narrow bight fringed by tall reeds and bulrush, where, concealed in friendly covert, we can continue the observation while glancing along the barrel of a punt-gun. That secondary fact is merely incidental and, it so happens, facilitates the main object.

A mile to windward three such armies are mobilising separately within the scope of our view; and now the gentle force of that sea-breeze begins to impel those unconscious hosts, too preoccupied with all-absorbing passion to notice detail, directly towards the point whereat we lie concealed.

REED-BUNTING
A winter visitor to the marismas.

By this time the sun has three or four hours of declension and the thin dark line representing thousands of surging atoms has drifted down to within 200 yards. We can study at short range an amazing phenomenon. In weird exuberance they fight and flirt, chase, cherish, and flap till churned water flies in foam and a discordant roar of sibilant sound fills to the zenith the voids of space. The volume of voices defies description since these assembling multitudes belong to no single species, but include a promiscuous agglomeration of all that care to enlist, and each adds its own distinctive element to the general uproar.[65] Around the floating host new-comers buzz like swarming bees, each seeking some spot to wedge itself into the crowd.

To-night the main corro that we had been awaiting drifted past our front a trifle beyond effective range. The two that followed both “took the ground” and remained stationary, away to the right. The chance of making a great shot had failed; but we were content to watch the phenomenon to its finish.

Now the sun dips. The western sky is filled with golden glory; in twenty short minutes darkness will have enveloped the earth. Then in a moment, as by word of command, silence, sudden and impressive, reigns where just before that torrential babel had raged. Such, now, is the stilly silence that by comparison the pipe of a passing redshank sounds well-nigh scandalous! A few seconds pass. Then, dominated by a single impulse, the concentrated mass on our front rises simultaneously on wing. The spell of silence is broken; the roar of pinions reverberates far and wide. They’re off—bound for Siberia!

Yet unperplexed as though one spirit swayed
Their indefatigable flight.

Holding the same massed formation, the fowl in three or four broadening circles quickly attain a considerable altitude—say 100 yards—and then head away on their course, ALWAYS (so far as they remain visible) to the SOUTH-EAST—diametrically opposite to the direction one would expect. As in deepening darkness we set forth on our homeward voyage, the heaven above pulsates at intervals with the beating of wings as yet more north-bound corros pass overhead.

Certain notable facts are observable in this vernal exodus. For upwards of twelve hours prior to departure the outgoing fowl take no food. That period is devoted exclusively to preparation and overhaul, and to pairing. Plumage is preened and dressed till each unit is spick and span, speckless, and not a feather misplaced. All, moreover, are absolutely empty—in best and lightest travelling trim.

When ducks are acorrados—that is, formed into corros (the term is used thus in verb-form)—their normal watchfulness is relaxed. All thought and energy are concentrated on the impending event. Hence, at these periods they are apt to fall an easier prey to the fowler and on wholesale lines. The native gunners with their trained cabresto-ponies sometimes unite and enormous totals are secured as the result of a single joint broadside. The fowl thus obtained afford proof of the facts just stated, being all absolutely empty; besides which many different species will be killed at the one shot.[66] These men also state that the ducks start already paired and flying side by side; this, they say, explains the ferment and commotion of the previous hours—courting and sorting. Adult ducks, as previously indicated (p. 110), apparently pair for life; but since some species (such as wigeon) take at least two years to gain maturity, it is probable that the sexual phenomena which are so conspicuous in the corros represent the first pairing of the newly adult two-year-olds.

The most favourable time for the assembling of corros is on those days when great heat and calm at midday is succeeded towards evening by an extra strong sea-breeze. On such occasions very large numbers will leave between sundown and dark. Northerly winds will almost absolutely arrest the exodus.

For the season of 1900-1901 our game-books showed a total of 4849 wildfowl (4674 ducks and 175 geese)—a record for which we were good-humouredly taken to task by our venerable friend the late Canon Tristram, who thought it looked excessive. The figures certainly are big, but the next entry in the book reads:—

March 15.—This evening between fifty and seventy corros left within half an hour—say 50,000 to 70,000 ducks. Next morning the marisma appeared as full as ever.

Our toll of 5000 seemed by comparison but as a drop in the bucket!

CHAPTER XXXIX

SPRING-TIME IN THE MARISMAS

BIRD-LIFE IN A DRY SEASON

BIRD-LIFE in the Spanish marisma—in spring no less than in winter—presents spectacles of such abounding variety as can nowhere in Europe be surpassed. In the Arctic are vaster aggregations, but these, comprising, say, only half-a-dozen species, are less attractive. It is the infinite kaleidoscopic succession of graceful and dissimilar forms that hour by hour flash on one’s sight—in a word, it is variety that lends abiding charm to our Spanish bird-world.

GREY PLOVER (May)
GREY PLOVER (May)

These scenes have already been described—we have ourselves described them in detail, and do not propose to recapitulate, alluring though the subject be.

Here we purpose depicting bird-life under undescribed conditions—in a spring when, by reason of exceptional drought, the myriad marsh-dwellers find themselves entirely at fault. Winging their seasonal way from Africa, to seek the seclusion of reed-girt pools and their accustomed league-long swamps and shallows, they found instead a calcined plain, no drop of water remaining, plant-life either prematurely parched or pulverised beneath a fiery sun. Watching the arrival of the advance-guard in early spring, one wondered what the bewildered hosts would do next, how they would face this fresh freak of nature.

The marismas, it should be explained, normally dry every summer, however wet the previous winter may have been. Though the great lucios stood five feet deep in February, yet the deepest will be stone-dry by midsummer or, at latest, by St. Jago (July 24). Cattle and the wild-game can then only drink at the narrowed pools where permanent water, however exiguous, oozes forth—or the cattle from wells. In normal years, however, the marsh-birds have already reared their broods before these dates.

But in years of drought—what resource have they, where can they find a substitute for their sun-destroyed and desolate incunabula? Many (the waders in particular) instinctively prognosticate a drought; few, comparatively, either come or remain—those that come pass on. Even such birds as breed on permanent deep-water lakes (such, for example, as the smaller herons, egrets, and ibises) perceive in advance that, although they may have water assured, there will neither be sufficient covert, later on, to conceal their nurseries nor food for the rearing of their young. The erewhiles teeming heronries are abandoned.

Never within forty years has there occurred a drier season than this last, 1909-10. Incidentally we may remark that most of the previous spring-tides that we had expressly devoted to the marisma had been years of excessive rainfall, years when flamingoes nested abundantly—an unfailing index. Such was 1872, for example, 1879, and 1883; again, in April 1891, we remember our gunning-punt, caught in a squall, sinking beneath us in quite three feet of water though barely a mile from shore. These are the seasons when (as described in Wild Spain) one sees the waterfowl in their fullest abundance. On the present occasion (1910) we were to witness converse conditions. Throughout the preceding winter the fountains of heaven had been stayed, nor did the advent of spring bring one hour of rain. By mid-March the marisma was practically waterless—a fortnight later, sunbaked hard as bricks. Where now were the marsh-birds? In April or May you could ride a long day over arid mud-flats and never see a wing, bar, in the latter month, a few Kentish plovers and fluttering pratincoles[67]—add a band or two of croaking sand-grouse (Pterocles alchata) passing in the high heavens. Where had the exiled myriads gone? No man can answer.

We are not so foolish as attempt to say; but we do venture to express the opinion that in years when even wildest Spain refuses asylum to wild creatures such as these, the result to them can only represent an overwhelming catastrophe. For there lies before them no alternative refuge; their races must perish by wholesale.

At those rare points where permanent waters remained one might look for great concentrations of bird-life, yet such was not the case. As indicated, the bulk had foreseen the event and abandoned this country.

One phenomenon struck us as inexplicable. Of the birds that did remain none displayed the slightest symptom of yielding to the vernal impulse, of pairing, or of desiring to nest.

Flamingoes, for example (what few there were), continued massed in solid herds up to mid-May. A band of 300 that we examined closely on the 12th at the Caño de la Junquera (though fully 90 per cent were adults in perfect pink feather) contained not a single paired couple. Hard by the flamingoes some forty or fifty spoonbills were feeding. These, last year, nested at this spot, building upon or among the low samphire-scrub—a dangerously open situation for such big and conspicuous birds. This spring, though many remained in the marisma, not a spoonbill nested in the district at all. Flamingoes, by the way, had exhibited extreme restlessness throughout the spring. On February 22, for example, while steaming up the Straits of Gibraltar, we detected them in quite incredible numbers but at an altitude almost beyond the range even of prism-glasses—it was a dim similitude to drifting cirri that first caught our eye. So vast was their aërial elevation that it was only after prolonged examination we at length recognised those revolving grey specks as being birds at all; presently a nearer band, directly overhead, revealed their characteristic identity. The bulk of these held a southerly tendency, towards Africa; others drifted undecided; while several bands, halting between two opinions, when lost to sight were wheeling beyond the Spanish hills.

Ducks also in mid-May serried the skies in utterly anachronous skeins—reminiscent of winter. These were largely marbled ducks, all unpaired; but there were also very large aggregations of mallards. One such pack on May 10 certainly counted 500—a number we never remember to have seen massed together in Spain before, not even in winter. This was at the Hondon. A similar phenomenon was observed with the white-faced ducks. These curious creatures also remained in packs, and without sign of pairing, on the open waters of Santolalla—open only because aquatic plants had forborne to grow. In normal seasons these lakes are studded with great cane-brakes and islanded reed-jungles, within whose recesses these amphibians build their floating homes. This spring not a reed had grown—partly owing to cattle having destroyed the earlier shoots which are usually protected by deep water. There was literally no covert within which these ducks (and the swarming coots and grebes) could breed, even were they so minded—which they were not!

The only ducks that had paired in earnest were gadwall, garganey, common and white-eyed pochard (of which the first three nest here in very limited numbers), together with normal quantities of mallard.

HEAD OF CRESTED COOT The frontal plate is concave, whereas in the common coot it is convex.

The frontal plate is concave, whereas in the common coot it is convex.

A collateral result of the shortage of water wrought yet further havoc among the birds which had elected to remain, and accentuated the prescience of those that had departed. Nesting-places, ordinarily islanded in mid-water, were now left stranded on dry land and thus open to the ravages of the whole fraternity of four-footed egg-devouring vermin. Many species, we know, foresee such risks and invariably avoid them; others, less prudent, make the attempt and lose their labour. The white-eyed pochards, for example, which are accustomed to nest in islanded clumps of rush and dense aquatic grasses, this year simply provided free breakfasts to rats and ichneumons! We happened to require two or three settings of these ducks to hatch-off under hens, but no sooner did a marked nest contain three or four eggs than all were devoured! As to the coots, of which both the common and crested species breed in the marisma in myriads, they simply gave it up as a bad business. They did not depart, but resigned themselves to the necessity of skipping a season.

Gulls, great and small, with graceful marsh-terns, floated spectre-like, surveying in solitude and silence arid wastes where before they had found aquatic Edens. Once or twice we also noticed the small white herons (buff-backed and egret) flying disconsolately over their lost homes. A similar remark would apply to most of the other marsh-breeders—we need not recapitulate them all. Stilts, for example, and avocets remained perforce in single blessedness—the latter in noisy querulous bands, quite wild and showing no tendency to assume spring notes or habits. We did chance on a single avocet’s nest, where, in other years, we have found hundreds. The same with the stilts—they also retained winter ways. Curiously on May 17—one wet day—two male stilts had a regular set-to over an irresponsive female; the only symptom of their love-making we noticed all that spring!

AVOCETS FEEDING Though long-legged, these are half-webfooted and swim freely.

Here, in the very height of what ought to have been the breeding-season, we had all these birds (and many others), instead of hovering overhead and shrieking in one’s ear, flying wild in great packs at 100 yards.

How came it to pass that the normal vernal impulse was neglected for a whole season, unfelt and unrecognised—what was the precise psychological reason? It reads ridiculous to assume that any feathered husband should deliberately remark: “Now, Angelina, don’t you agree that it would be imprudent our attempting to raise a family this drought-struck season?” Nor could the neglect arise from physical weakness, since the birds were strong and wild. Such specimens as we shot proved plump and well favoured, though the generative organs disclosed a hybernal obsolescence. One explanation—indeed a rough-and-ready diagnosis that seemed to cover the ground—was given by Vasquez. Now Vasquez is our Guarda of the marisma; he is not scientific, but has been in charge of the wilderness and its wildfowl these thirty years and, more than all, he is observant. This rough keeper perhaps understands the inner lives of wildfowl, with the causes that actuate their movements and habits, better than our best scientists, and Vasquez told us in February: “This year no birds will breed here; the conditions necessary to calientár los ovários [literally, to warm up the ovaries] are wanting.” The subsequent course of events, corroborated by the evidence of dissection, proved the correctness of his forecast.

 

For a moment we return to the white-faced ducks—no European bird-form less known, or more extravagant. With heavy, swollen beaks, quite disproportionate in size and pale waxy-blue in colour, with white heads, black necks, and rich chestnut bodies, their tiny wings (as well as the sheeny silken plumage) recall those of grebes, but they have long stiff tails like cormorants, and are more tenacious of the water than either of those. To push them on wing is well-nigh impossible. They seek safety in the middle waters and there abide, ignoring threats. To-day, however (May 16), we needed specimens, and by hustling their company between three guns, two mounted keepers, and an old boat that leaked like a sieve we eventually forced them to fly and secured three. They flew entirely in packs (not pairs), rarely many feet above the surface, but with a speed little inferior to pochard or other diving-ducks. Dissection showed that in a female the ovaries had not begun to develop, there were no ripe ova, nor had the oviduct been used. The testes in both the males proved also that here these birds were not yet breeding, or thinking of doing so.

A week earlier, however, at another lake of quite different formation and different plant-growth (thirty miles away), we had found these singular waterfowl already nesting, and append a note of that day:—

Laguna de las Terajes, May 8.—A lonely lagoon hidden away in a saucer-shaped basin amidst sequestered downs; almost the entire extent (twenty acres) choked with dense cane-brakes and thick green reeds which stood six or eight feet above water. We had driven hither, nine miles, across sandy heaths and pine-wood; and while breakfasting on the shore our two canoes (carted here yesterday) were got afloat. Meanwhile, on a patch of open water we had observed several white-faced ducks swimming, deeply immersed, and with their long stiff tails cocked upright at intervals, together with some eared grebes; while marsh-harriers slowly quartered the brakes and the reed-beds rang with the harsh nasal notes of the great sedge-warbler. On pushing out into the aquatic jungle ahead—no light labour with five feet of water encumbered with densely matted canes and the dead tangle of former growths—we soon fell in with nests of all the species above mentioned and several more. Those of the white-faced ducks consisted, first, of a big floating platform of broken canes, upon which was piled a mass of fine dried “duck-weed”—the coots’ nests being formed of flags and reeds alone. None of the ducks’ nests contained eggs; probably the season was too early (in other years we have found their great white eggs, rough-grained, about the third week in May), but possibly the harriers had forestalled us, as we found one egg floating alongside. The grebes were just beginning to lay; their nests, composed of rotten floatage, all awash and malodorous, containing one to three eggs. Next we found two nests of marsh-harriers, immense masses of dead flags, two feet high, supported on floating canes and lined with sticks, heather-stalks, and palmetto. One had four eggs, hard-sat; the other, two eggs, chipping, and two small young in white down, with savage black eyes. The harriers’ eggs are usually dull white; in one nest found this year, however, the eggs were spotted with pale red—apparently blood-stains. Hard by were two nests of the purple water-hen, both of which had obviously been recently robbed by the harriers next door.

These curious birds climb the tall green reeds parrot-wise, grasping four or five at once in their long, supple, heavily clawed toes; then with their powerful red beaks neatly cut down the reeds a yard or more above water, in order to feed on the tender pith. Here and there float masses of these cut-down reeds, split and emptied—comederos, the natives call such spots. But the birds are silly enough to cut down the very reeds that surround their nests—thus exposing the huge piled-up structures to the gaze of their truculent neighbour, the egg-loving marsh-harrier. Instinct badly at fault here.

With a degree more intelligence, the purple water-hens might at least retaliate, by watching their opportunity and mopping-up the harriers’ young. They are amply equipped for such work, having great pincer-like beaks fit to cut barbed wire!

On the other hand, the great purple water-hens habitually do a bit robbery and murder on their own account, plundering the nests both of ducks and coots and devouring eggs or young alike. We shot one whose beak was smeared all over with yolk from a plundered duck’s nest hard by, and alongside the nest of a Porphyrio with five eggs (found May 1) lay floating the head-less corpses of two young coots. We have also observed similar phenomena alongside the nests of the coots themselves—doubtless attributable to the same cause. The eggs of the purple water-hen are lovely objects, ruddier and much more richly coloured than those of any of its congeners. These birds remain in the marismas all winter.

In the densest brake bred purple herons, but this part proved quite impenetrable to canoes. A few days later, however, at the Retuerta, we reached a little colony of three nests. A beautiful sight they presented, broad platforms of criss-crossed canes, cleverly supported on tall bamboos, and lined with the flowering tops of carrizos (canes). These three nests were close together (another or two hard by), were about five feet above water-level, and contained three, three, and four pale-blue eggs. While circling around their nests, the old herons showed a conspicuous projection beneath their curved necks. We therefore shot one and found the effect was caused by a curious “kink” or bony process on the front of the upper neck—as sketched.

Of other birds observed at this Laguna de Terajes may be noted a few mallard and marbled ducks, a pair of squacco herons (not breeding), common sandpipers (on May 8), and a party of whiskered terns which arrived while we were there.

The day we had spent among the marsh-birds at this sequestered lagoon happened to be the day of the general election and the usual excitement prevailed. Yet, as we journeyed down by the early train, we had read in the morning’s paper this paragraph: “An understanding” [Inteligencia]—“Yesterday an understanding was arrived at in Madrid between Maura and Cañalejas, by which the former is to hold 225 seats.” Why, after that, bother further with an election? ‘Twill serve as an object-lesson at home.

Another phenomenon of the Spanish marismas is the through-transit in May of that little group of world-wanderers that make a winter-home in the southern hemisphere—in South Africa and Madagascar, Australia, New Zealand, some even in Patagonia—and yet return each spring to summer in Arctic regions. These comprise, notably, but four species, and not one of these four, in our view, is excelled for perfect beauty of bright, chaste, and contrasted coloration by any other bird-form on earth. This quartette is composed of the grey plover, knot, curlew-sandpiper, and bartailed godwit—all four of which appear here in thousands every May, and all in summer dress.

Note, first, that these do not arrive in Spain (having come 6000 or 8000 miles but being still 2000 or 3000 miles short of their final destination) until long after all other birds—including several congeneric and closely related species—have already laid their eggs and many hatched their young. Also, secondly, that some of them begin to assume their spring breeding-plumage under autumnal conditions before quitting Australia in April—that is, the Australian autumn—and while yet some 10,000 miles distant from the points at which that breeding-dress is designed to be worn.

To the four named might properly be added other two species—the sanderling and the little stint. Our only reason for confining our remarks to the original quartette is that, in Spain, the transit of the other two is less pronounced and noticeable.

Last spring (1910), dry as the marismas were, we had these globe-spanners in thousands. They were extremely wild, and it was only by elaborate “drives” that we secured a few specimens.[68] We also observed in mid-May hundreds of black-tailed godwits, a species which usually disappears from southern Spain at end of March and which we have found nesting in Jutland before the above date, viz. the first week in May.

Whimbrels had been extremely abundant early in May, together with a few greenshanks, ring-dotterel, and green sandpiper. On May 13 we observed several of the Mediterranean black-headed gull (Larus melanocephalus) on Santolalla.
