Chickadee-Black


The Black-Capped Chickadee hides seeds and other food items for later recovery. Each item is placed in a different spot and a bird can remember thousands of hiding places. The chickadee's simple-sounding calls have been found to be extremely complex and language-like. They code information on identity and recognition of other flocks as well as predator alarms and contact calls. Breeding pairs and nonbreeders join up into flocks outside of the breeding season. Nonbreeders may be members of several flocks, with a different position in the dominance hierarchy of each flock.Black-capped Chickadees have benefited from human-provided food and nest boxes, as well as increased forest edges caused by deforestation. However, overzealous forest management can reduce or eliminate natural nest sites.
