I can confirm with firsthand experience that crows fucking love unsalted cashews. I don’t know if it’s the flavor, distinctive shape, or the texture, but there was a family of crows at my old house that used to go bugfuck wild when I gave them cashews.

I used to buy them in bulk as a snack, so I always had a lot on hand. I’d usually put them in a little plastic cup if I was going outside. One time I spilled some on the patio and didn’t bother cleaning them up. The next time I was outside and had a cup of them, that family of crows was extremely interested. I left a few on the patio as an experiment and went back inside. As soon as I was inside, they were on those cashews like flies on shit.

From then on, whenever I happened to take that plastic cup outside, I’d have a family of crows waiting for the traditional offering of cashews.
