This crabapple tree is bird food, not people food. When I was a kid, we used to try to eat crabapples, but they are so sour! I know some people make crabapple jelly - it takes a lot of sugar. Birds I see feeding on this tree, either the fruit or the bugs in the bark, and mostly in the winter and spring: starlings, blackbirds, robins, evening grosbeaks, finches, juncos, flickers, and downy-headed woodpeckers. It's a great show!
