They sometimes gather in large flocks of hundreds of birds and will circle high on the thermals (high, warm winds). The pied crow is highly adaptable to many sorts of environments including the human where it scavenges. Pied crows are known for mobbing birds of prey. Enrichments at the Zoo: Food or insects are put into a container, carton or tube so that the bird must find a way to get out the treats.

BREEDINGPied crows can breed throughout the year. The nest are made of sticks and lined with soft materials including fibers, hair, wool, rags, paper or fibrous bark made by both the parent placed either in trees or niches in rocks or on the cross supports of telephone poles.
