PERCHED COOPER'S HAWK, COLONEL SAMUEL SMITH PARK, ETOBICOKE, TORONTO, ONTARIO, 1/31/2026
The bright white spots on the back of the Cooper's Hawk could be due to the fluffing of its feathers. According to Sibley Birds East all perched accipiters (Cooper's Hawk is an accipiter) can show bright white spots on their back when their feathers are fluffed. Birds fluff their feathers in cold weather to keep warm by trapping air, which acts as insulation against the cold.
