Francis Heatherley, The Peregrine Falcon at the Eyrie… (1913)
“ Although in my belief the Tiercel is fiercer and bolder than the Falcon, yet in the relaxation of the eyrie I have seen him, when wailing to the Falcon to bring him food for the young, assume a whimsically childlike and plaintive expression that might have evoked sympathy from a dove. Those who remain unsatisfied—and I hope there will be many—have only to spend a little time and trouble in making a hiding-shed and finding an eyrie, and then they will see something far better—the birds themselves. ”
