The Report for the West Coast of England and Wales, and the Isle of Man, refers to the seasonal movements during 1886 of 104 species. The first vernal migratory movement occurred on the 24th of March, and was sustained until the 26th. During this interval _Phylloscopus trochilus_, _Saxicola œnanthe_, _Pratincola rubicola_, and _Hirundo rustica_, along with _Turdus iliacus_, _T. pilaris_, _Scolopax rusticula_, and also _Turdus musicus_, _T. merula_, and _Alauda arvensis_, were observed--all at the lanterns, save _Hirundo rustica_, which occurred during the daytime. The weather prior to this initiatory migration had been severe and unsettled, and the movement was concurrent with the temporary prevalence of favourable conditions (_see_ p. 82) over our Islands.
