About This Book

An illustrated, systematic account of birds observed during the expedition, offering formal species descriptions, diagnostic characters, and notes on habits and geographic range. The volume combines taxonomic commentary and synonymy, frequent corrections and generic adjustments, and a series of hand-colored plates depicting specimens at life size or reduced scale. Supplementary material includes an observer’s concise summaries of behavior and distribution and an anatomical appendix detailing structure and comparative morphology. The work emphasizes identification, variation among closely related forms, and the practical records made during field collecting.

Family.—HALCYONIDÆ.

Halcyon erythrorhyncha, Gould, Proc. Zool. Soc. 1837.

Alcedo Senegalensis var. β, Lath.

In January, during the first visit of the Beagle to St. Jago, in the Cape de Verd Islands, these birds were numerous. But in our homeward voyage, in the beginning of September, I did not see a single individual. As Mr. Gould informs me it is an African species; it is probably only a winter visitant to this archipelago. It lives in numbers in the arid valleys in the neighbourhood of Porto Praya, where it may be generally seen perched on the branch of the castor oil plant. I opened the stomachs of several, and found them filled with the wing cases of Orthopterous insects, the constant inhabitants of all sterile countries; and in the craw of one there was part of a lizard. It is tame and solitary; its flight is not swift and direct like that of the European kingfisher. In these respects, and especially in its abundance in dry rocky valleys where there is not a drop of water, it differs widely from the habits of the allied genus Alcedo; although certainly it abounded more in those valleys where streamlets occurred. This Halcyon was the only brilliantly coloured bird which I saw on the island of St. Jago.

1. Ceryle Americana. Boie.

Alcedo Americana, Gmel.

This Kingfisher is common on the banks of the Parana. It frequents the borders of lakes and rivers, and sitting on the branch of a tree, or on a stone, it thence takes short flights, and dashes into the water to secure its prey. Its manner of flying is neither direct nor rapid, which character is so remarkable in the flight of the European species; but it is weak and undulatory, and resembles that of the soft-billed birds. It often arrests itself suddenly in its course, and hovers over the surface of the water, preparatory to darting on some small fish. When seated on a twig it constantly elevates and depresses its tail; and as might have been expected from its figure, it does not sit in the stiff upright position so peculiar to the European Kingfisher. Its note is not unfrequently uttered: it is low, and like the clicking together of two small stones. I was informed that it builds in trees. The internal coating of the stomach is of a fine orange colour. Mr. Gould has seen specimens of this bird from Mexico; it enjoys, therefore, a very wide range.

2. Ceryle torquata. Bonap.

Alcedo torquata. Gmel.
Ispida torquata. Swain.

This bird is common in the south part of Chile, in Chiloe, the Chonos Archipelago, and on the whole west coast, as far as the extreme southern parts of Tierra del Fuego. In these countries, it almost exclusively frequents the retired bays and channels of the sea with which the land is intersected; and lives on marine productions. I opened the stomach of one, and found it full of the remains of crustaceæ, and a part of a small fish. It occurs likewise in La Plata, and is very common in Brazil, where it haunts fresh water. It is said (Dict. Class. d’Hist. Nat.) to occur in the West Indian islands; it has, therefore, a wider range (from the equatorial region to the neighbourhood of Cape Horn) than the Ceryle Americana.
