Francis Heatherley, The Peregrine Falcon at the Eyrie… (1913)
“ But the whimpers disturb her until at last every time he opens his beak she bends over and puts hers into it, as if feeding him, or else closes his beak with her mandibles. Presently he leaves her and gets down into the eyrie to look for something to eat. He attacks the stem of the giant mallow growing in the eyrie, and gets his talons so deeply into it that he has to fall down and flutter about before he can get free. At 7.15 p.m, the Tiercel arrived with a bird and devoted himself entirely to this hungry male at first. ”
