The Black-crested Titmouse (Baeolophus atricristatus) is a small songbird in the tit family Paridae. Once considered a subspecies of the Tufted Titmouse, it is now recognized as a separate species. It is native to southern Texas, Oklahoma, and east-central Mexico. The Black-crested Tit is also known as the Mexican Titmouse.
The bird is 5.5 to 6 inches long, with rusty flanks, gray upper parts, and a whitish belly. The male has a long, dark black crest that is usually erect, while the female’s crest is not as dark. It is common wherever trees grow, whether they are deciduous, heavy timber, or urban shade trees. Its diet consists of berries, nuts, spiders, insects, and insect eggs.
The Black-crested Titmouse nests in tree cavities, telephone poles, fence posts, and bird boxes. The eggs, four to seven of which are laid in March or April, are white with reddish-brown spots.
