The black- hooded tit ( Baeolophus atricristatus ) is a songbird species from the family of the titmouse (Paridae) found in North and Central America .
description
Appearance
The black-hooded tit reaches a total length of 14.5 to 15.0 centimeters, with the tail making up about a third of the length. It is black-gray in the males and brown-gray in the females. The weight varies between 15.5 and 20.9 grams. A dark colored feather bonnet is typical of the species and is only rarely put on. This is glossy black in the males and dark brown in the females. Other external distinguishing features of the sexes are minimal. Head, chest and belly are whitish to cream-colored, light orange-brown on the rear flanks. The back plumage and the wings have a lead gray color. The beak is short, strong and blackish horn-colored. The iris is black. Legs and feet are slate gray.
Vocalizations
The call of the black- hooded tit is similar to that of the Indian titmouse ( Baeolophus bicolor ) and is a bright-sounding Pieter - Pieter - Pieter , but is called in quicker succession.
distribution and habitat
The distribution area of the black-hooded tit stretches from southeast Texas and southwest Oklahoma to northeast Mexico . It prefers to live in oak ( Quercus ) or mixed forests . The maximum altitude is 2300 meters.
Way of life
During the breeding season in summer, the pairs live individually. You are monogamous . In winter they can often be found in groups. They feed primarily on various types of insects and arachnids, as well as berries and nuts .
The nest is created in existing cavities in trees up to a height of seven meters. The female is solely responsible for building the nest. It builds the nest out of moss, dry grass, dry leaves and animal hair. The eggs are laid between February and June. They have a white base color and are covered with small brown, reddish or purple spots. Sometimes a second brood also occurs. A clutch usually consists of five to six eggs. The females then incubate for 12 to 14 days. Both parents feed the nestlings. The young fly out after 15 to 16 days.
Danger
The black-toed tit is not uncommon in its distribution areas and is therefore classified by the IUCN as a 
" least concern ". It is protected by the United States Fish and Wildlife Service under the Migratory Bird Treaty Act .
Taxonomy and subspecies
The black-hooded tit was previously considered a subspecies of the tufted titmouse. Due to genetic differences, it has been listed as an independent species with three subspecies since 2002:
- Baeolophus atricristatus atricristatus ( Cassin , 1850)
- Baeolophus atricristatus paloduro J. O. Stevenson , 1940
