Who called in the airstrike?

So I was feeding the crows in the park this morning, as I do nearly every morning. Usually they just sit there, wait for me to toss a treat toward them, then hop over/down and pick it up, and look at me for a few seconds before either eating or caching it. Once I've fed all the visible crows, I leave the area, and they go do their own thing. One of them, though, has upped the ante and is trying some new strategies in order to get more treats. It will now follow me, if I take a route other than my normal route through the park. It even crossed the road as I left the park today, they never do that. Anyway, as well as the following, it will fly really close to me, to attract my attention, then land in front of me, as if to say "hey, right here, look at my pretty crow self, now give me a treat" Of course it works, because I am a sucker for corvids. I'm hoping to get it to eat out of my hand eventually, maybe land on my arm or something. We'll see. And to stave off any concerns that I am training crows to land on people - they do not approach anyone else, or even me if I either - have someone else with me - or - don't have the Pie with me. They seem to only recognize the Emily-Tasha combination. Wearing a different jacket puts them off, but they figure that out pretty quick.
