distribution and habitat

The distribution area of ​​the bridle tit stretches from southern Arizona and New Mexico to Mexico . It prefers to live in oak forests ( Quercus ), occasionally also in mixed forests .

Way of life

During the breeding season in summer, the pairs live individually, after which they can often be found in groups. They feed primarily on various types of insects and arachnids , and sometimes they peck at acorns.

The nest is created in existing cavities in trees. The eggs are laid between April and June. A second brood occurs only when the first is lost. A clutch usually consists of five to seven eggs. The females then incubate for 13 to 14 days. The young fly out after 18 to 20 days. In North America, the bridle tit is the only species in which conspecifics participate in the rearing of the young.

Danger

The bridle tit is not uncommon in its areas of distribution and is therefore classified by the IUCN as a LC IUCN 3 1st svg“ least concern ”. It is protected by the United States Fish and Wildlife Service under the Migratory Bird Treaty Act .
