Report on the Migration of Birds in the Autumn of 1879. [First Report]

This scientific report represents a pioneering effort to systematically study bird migration across the British Isles during the autumn of 1879. Compiled by ornithologists John Cordeaux and J. A. Harvie-Brown, it marks the first organized report under the British Association for the Advancement of Science’s Migration Committee. The work is an essential milestone in avian migration studies, reflecting an era of growing interest in natural history and methodical data collection. The report synthesizes observations gathered from a network of lighthouse and lightship keepers, who meticulously recorded the movements of birds during the autumn migration. It details species sighted, flight patterns, weather conditions, and times of migration, offering valuable insights into the seasonal behavior of various avian populations. Particular attention is paid to weather influences, such as wind direction and storms, which were observed to significantly affect migratory routes and timing.
