I had a similar thought today when feeding some crows. Usually they don’t like it when other people show up, and they leave or hide for a bit in a tree or some such. So by proxy I don’t like having people around since we all have to wait. It’s a nice bit of converged purpose I guess where I adapt my behavior as well. Most people who go there are usually oblivious of any birds. They just don’t see it.
I have found that they like dry, unsalted popcorn. They also like small kibbled dog food, and really go nuts over dried cranberries and unsalted almonds. If there are sunflower seeds in the mix, they are always the last to be eaten.
An expert recommended it above most things. They like some insects above all, but sunflower seeds mostly. They pretend to like bread, but they usually hide it in a stash and don’t eat it unless they really hungry.
There's just something absolutely enchanting and quaint about being friends with crows, and learning what your local murder's favorite foods are absolutely let's you get in their good graces faster.
