Lol...*sigh*...I can't help but think Radisson is using some sort of new peregrine psychology on Cassie...'if i fill the box up with enough creepy stuff then she'll have to come and fly with me".
Revenge of the Peregrines?
Night of the Living Gulls?
Defeathered?
The Gull Snatchers?
Nestbox of Horror?
And wow it is hot there today, that explains why the parents aren't being as aggressive with fly bys like they were yesterday - that's way too hot for them.
