Is it a rook, raven or crow? The three all-black corvids cause a common ID challenge but they can be identified by their size, shape and calls.
Corvids tend to have strong social groups and communities. Crows for example, often mate for life and are co-operative breeders, meaning other adults in the family help with rearing offspring.
