This is the first observation I made. These rowdy birds were around my apartment most evenings for a while and I always wondered what they were. Some suggested they were grackles as they are very common in our area, but after doing some research I found out these birds are actually American Crows. Some notable differences are that crows are pitch black while grackles have some blueish tints in their feathers. Also, there calls are very different. Grackles produced very high-pitched sounds while crows produce sounds more like “caw-caw.”
