No matter how old you get, you never stop learning new things. When you learn something new, share your knowledge with the rest of us by posting it here. Today I learned why crows divebomb at squirrels. I see this a lot and it's appalling how they pick on small rodents who can't fly. On the local news today, they showed a crow that was actually divebombing people, right in front of a bridge walkway. I thought they just did it because crows are mean, but it turns out, the crow on the news was defending a nearby nest. He just happened to build the nest on the tree right next to the bridge. So there you have it. If a crow divebombs you, it thinks you're a threat to its nest, so....just walk away.
