The Report for the West Coast of England and Wales, and the Isle of Man, refers to the movements during the spring and autumn migrations of about one hundred species.
The spring immigration commenced on the 25th of March with the advent of the Swallow at the Bahama Bank light-vessel, and continued until the 15th of May, when "very many" Swallows appeared between 4 P.M. and 7 P.M. at Langness. A noteworthy incident of the vernal immigration was the great rush of Wheatears observed at the Bahama Bank vessel and at Langness on the night of the 13th of April, when many perished or were captured.
The spring emigration did not escape attention, for on the night of the 20th of April the returning Fieldfares, Goldcrests, etc., were observed at 11 P.M. at the Chickens Rock. Perhaps the continuous movements of Thrushes and Blackbirds observed throughout February, and especially between the 11th and 17th, are referable to this class of migrants.
