Mother's Day with Cockatoos and Crow

Mother's Day dawned clear, bright and chilly and the sulphur-crested Cockatoos were out in force. This group of 15 had a black crow badgering them sorely.

Caw, caw, caw. Caw, caw, caw. When they flew away he chased two of them down the street. Did he want to be friends or had they invaded his territory?
