The family Paridae includes 12 species found in North America.

Chickadees and Tits occur in Eurasia, Africa and North America south to Mexico. They are found mainly in woodlands and forests. Among the smallest of birds (11-15 cm.), they are small-billed. They have fluffy body plumage. In winter they travel in small flocks with other species. Chickadees and Tits feed on insects gleaned from foliage and bark, seeds and berries. They will readily come to feeders. They nest in tree holes or other cavities. Eggs are plain white or with reddish speckles.
