Paridae are small, active passerines found primarily in the Northern Hemisphere and Africa. They are known for their acrobatic foraging, often hanging upside down to glean insects from branches and leaves. Their plumage is typically a mix of black, white, gray, and sometimes yellow or blue. Parids are cavity nesters, often using abandoned woodpecker holes or natural cavities in trees. They are social birds, frequently found in flocks, especially outside of the breeding season.
