The male will fluff his feathers, strut, and fly by, in his attempts to win over the female. Once mated, crows usually mate for life. Not only will crows defend and protect their own family, but they will come to the aid of unrelated crows in need or distress. Crows are cooperative breeders. Both crow parents take turns sitting on the eggs.
All family members help in the care of the brood.
