Francis Heatherley, The Peregrine Falcon at the Eyrie… (1913)
“ At 4.50 a.m, the Falcon is calling the long-drawn-out, gull-like food cry, to which he immediately replies with the same cry and flies out to meet her. She transfers the quarry from her talons to his in the air. He brings it in, a song thrush, an adult, and quite intact, head and all. He feeds the young with it, occasionally swallowing a piece himself. He is very careful to pick up any morsel that misses a youngster's beak and drops into the eyrie and carefully offers it again. He holds the quarry firmly under one foot and tears pieces off with his beak. ”
