The black-crowned tityra (Tityra inquisitor) is a medium-sized passerine bird. [2] It is found in Mexico, every Central American country except El Salvador, and every mainland South American country except Chile and Uruguay. [3] [4]

Taxonomy and systematics

The black-crowned tityra has a complicated taxonomic history. It was originally described in 1823 as Lanius inquisitor, mistakenly placing it in the shrike family. [5] In 1851 Johann Jakob Kaup placed it in a new genus, Psaris; he noted that the genus was a synonym for Tityra that Viellot had erected in 1816. [6] [2] In the early twentieth century some authors placed it in its own genus Erator which was then merged into Tityra in 1929, though some authors in the 1970s urged the species' return to Erator. [7] All of the tityras were for a time included in the tyrant flycatcher family Tyrannidae before they, becards, and a few other species were assigned to their current family Tityridae. [8]

The black-crowned tityra has these six subspecies: [2]

Description

The black-capped tityra is 16.5 to 20.5 cm (6.5 to 8.1 in) long and weighs 33.8 to 70 g (1.2 to 2.5 oz). The species is sexually dimorphic. Adult males of the nominate subspecies T. i. inquisitor have a mostly black head. Their nape and upperparts are whitish gray with a pearly gray cast. Their wings are mostly black with grayish white tertials. Their tail is black. Their throat and underparts are white. Adult females have a buffy forehead and a black cap on an otherwise chestnut or rusty face. Their upperparts are a slightly darker gray than the male's with dusky brownish streaks and coarse blackish spots. Their wings and tail are like the male's. Their throat and underparts are washed with dingy pale grayish buff. [8]

The other subspecies of the black-capped tityra differ from the nominate and each other thus: [8]

Both sexes of all subspecies have a dark iris, a bluish gray maxilla, a blackish mandible, and blackish legs and feet. [8]

Distribution and habitat

The subspecies of the black-crowned tityra are found thus: [8]

The black-crowned tityra inhabits lowland evergreen forest and secondary forest in the tropical and lower subtropical zones. [3] It favors the forest canopy and edges, clearings and areas along waterways. It also is found in plantations and várzea forest. [8] In elevation it overall occurs from sea level to about 1,200 m (3,900 ft). [3] It reaches only 700 m (2,300 ft) in Ecuador, 600 m (2,000 ft) in Peru, and 1,100 m (3,600 ft) in Venezuela. [13] [11] [12]

Behavior

Movement

The black-crowned tityra is considered a year-round resident. [3] However, it appears to occur in western Oaxaca only in winter. [8]

Feeding

The black-crowned tityra feeds mostly on fruits and also includes invertebrates in its diet. It forages singly, in pairs, and in small family groups and only rarely joins mixed-species feeding flocks. It forages mostly from the forest's mid-story to its canopy, perching in the open and striking upward to take food from foliage. It less often gleans while perched and while briefly hovering after a sortie from a perch. [8]

Breeding

The black-crowned tityra's breeding season varies geographically. It includes May in Guatemala, March to June in Costa Rica, March and April in Panama, May to July in Colombia, May to August and possibly beyond in Venezuela, January to April in Ecuador, November and December in southern Brazil, and October and November in Argentina. The species nests in a tree cavity, often a woodpecker hole, on a bed of dead leaves, twigs, and other plant fibers. The clutch is thought to be three eggs. The female alone incubates, for about 18 to 21 days. Fledging occurs about 20 to 30 days after hatch and both parents provision nestlings. [8]

Vocalization

The black-crowned tityra is not highly vocal. It does make a variety of calls including "a husky grunting or dry guttural...variable sheh-shehk, squik or zick-zick-zick, and a series of low, weak, and nasal chet-chut, chaa-cherp notes". It also makes a "nasal grunting with buzzy quality, uurnt or uurnt-uurnt [and a] strange thin corre corre call". [8]

Status

The IUCN has assessed the black-capped titrya as being of Least Concern. It has an extremely large range; its estimated population of at least 500,000 mature individuals is believed to be decreasing. No immediate threats have been identified. [1] It is considered uncommon in northern Central America, "widespread but fairly uncommon" in Costa Rica, fairly common in Colombia, uncommon in Ecuador, "uncommon but widspread" in Peru, "fairly common but locally distributed" in Venezuela, and "frequent to uncommon" in Brazil. [9] [10] [14] [13] [11] [12] [15] It is found in many national parks and other protected areas. [8]
