At first, it was more-or-less luck as to who and when a crow found it. But they began to catch on, and I'm pretty sure at least one was waiting for me. They were either on the post, or nearby. They fly off when you approach, of course. But they get the idea, and I know they're watching. I try to step back, but they need quite a large distance before they'll try to take the biscuit. Crows seem to know that humans are always up to something. The probably know that it's always plans within plans when it comes to those damn hairless apes. Is he really being generous, or is he running some inscrutable psyop?
The problem is that I haven't been consistent the last few days, so the crows lose interest.
A few days ago, mind, there was a crow sitting on the fence a few feet from the house. He flew off as I left the house, but he didn't seem particularly alarmed. He flew up to the top of a conifer quite a few yards away. But I knew he was watching. So I put a biscuit on a post and went for a walk. When I came back the biscuit was gone.
I guess what I like about crows is that they're really smart, so you're always left wondering as to how much they've cottoned on to and how much of it is just blind coincidence.
