Report on the Migration of Birds in the Spring and Autumn of 1885. Seventh Report / (Vol. II No. 2)

A committee compiles observations from lighthouse and lightship station diaries around the British Isles documenting spring and autumn 1885 bird migrations. It lists stations and reporters, summarizes methods, and maps positions. The data show compressed, late spring movements concentrated in early May under prevailing easterly and southeasterly winds, pronounced but brief autumn rushes between mid-October and mid-November, and notable local events such as intense passages at the Isle of May and cross-directional flights of species like woodcock. Analyses emphasize rejecting the label accidental for regular but atypical movements and recommend continued systematic lighthouse-based monitoring.
