Abstract

Fledgling Double-crested Cormorants (Phalacrocorax auritus) were observed practicing food manipulation techniques with large sticks, algae, and shells at their respective natal colonies in eastern Lake Ontario, North Channel of Lake Huron, and Lake of the Woods. Although practice behaviors have been documented for other species of waterbirds, this behavior has not been recorded previously for Double-crested Cormorants.
