@ct_bergstrom re: safe crow snacks for anyone reading, a great option is to find your local speciality parrot shop and look at their offerings for large parrots. Crows aren’t hookbills of course, but the kinds of things that are tasty and safe for large, highly intelligent tool-using birds tend to be similar. You can buy a big bag of raw unsalted nuts, seeds, bits of dried fruits and veggies, and little pressed nugget type bits in bulk to amaze and amuse any bird inexpensively!
