The report assembles systematic observations of bird movements collected at lighthouses, lightships, and coastal stations around the British and Irish coasts during spring and autumn 1887. It lists stations and maps, presents regional returns, diary extracts from individual keepers, and a statistical synthesis that distils species occurrences, timing, directions, and notable occurrences such as nocturnal gatherings around lanterns and occasional captures or mortalities. Material is organized by coast and station, with tabulated returns and interpretive summaries to reveal migration patterns, seasonal peaks, and variations between districts.
