We have a pair of crows that are almost guaranteed to turn up very soon after I’ve thrown any crusts etc. on the lawn. Sometimes even before I’m back in the kitchen! Anything very dry is taken for a soaking in one of the bird baths, and they’ll typically pick up several bits until their beak can’t hold any more. I’ve seen them drop some, swallow some, and then pick up even more.
Scraps of leftover uncooked pastry are very popular!
They used to be extremely nervous - any slight movement even from behind the kitchen window would have them flying off, but they’re a lot less timid now.
