The eastern chat-tanager (Calyptophilus frugivorus) is a Near Threatened species of passerine bird belonging to the family Calyptophilidae. It is endemic to the island of Hispaniola, in the Dominican Republic; it is possibly extirpated from Haiti. [2] [1]
The eastern chat-tanager has three subspecies, the nominate C. f. frugivorus, C. f. neibae, and C. f. abbotti. Of these, only C. f. neibae is confirmed extant; the other two are considered extinct. It shares its genus with the western chat-tanager (C. tertius), which was previously treated as a fourth subspecies. The genus was long included in family Thraupidae, the "true" tanagers, but it was moved in 2017. [2] [3] [4]
The eastern chat-tanager is 17 to 19 cm (6.7 to 7.5 in) long and weighs about 26 to 39 g (0.92 to 1.4 oz). It has a long bill and a long tail so it somewhat resembles a mockingbird's shape. The sexes have the same plumage. Adults of the nominate subspecies have a dusky brown crown and a mostly dark grayish brown face with a yellow line between the bill and eye and a yellow ring around the eye. Their upperparts are dark olive-brown. Their throat and underparts are white with a heavy wash of grayish brown on the flanks and lower belly. Subspecies C. f. neibae is smaller and darker than the nominate and has a reddish tail. C. f. abbotti is slightly smaller and a more grayish brown than the nominate. [3]
The nominate subspecies of the eastern chat-tanager, C. f. frugivorus, occurred on the Samaná Peninsula on the northeast coast of the Dominican Republic but is considered extinct, with no records since the early 1980s. The subspecies C. f. neibae is found in the central Sierra de Neiba mountain range of the western Dominican Dominican Republic and possibly into Haiti. C. f. abbotti was found on Gonâve Island off the west coast of Haiti but is also believed to be extinct since the early 1980s; however, a lack of extensive surveys on the island means the subspecies potentially survives. [3]
In the Dominican Republic, the species inhabits dense undergrowth in montane forest, especially in ravines and along streams. C. f. frugivorus was mostly found below 600 m (2,000 ft) but C. f. neibae can range up to or above 2,000 m (6,600 ft). C. f. abbotti's habitat on Gonâve was semi-arid scrublands near sea level. [3]
The eastern chat-tanager is a year-round resident throughout its range. It is secretive and usually encountered on or near the ground. [3]
The eastern chat-tanager forages on or near the ground, usually in pairs. Its diet is mostly insects and other invertebrates with a small amount of fruit. [3]
The eastern chat-tanager's breeding season is thought to be May to July. Almost nothing is known about its breeding biology. Only one nest has been found; it was cup shaped, placed in a fern by a blackberry Rubus patch, and contained one egg. [3]
Both sexes of the eastern chat-tanager sing, usually at dawn. The species is "regarded as among the finest [singers] on Hispaniola". The nominate subspecies' song is "a low slurred or whistled 'swerp, swerp, chip, chip, chip...'" and that of C. f. neibae is "weet-weet-werp chip-cheep-sweet...". Both make "a sharp 'chin chin chin'" call. [3]
The IUCN has assessed the eastern chat-tanager as Near Threatened. It has a moderate sized range and its estimated population of 10,000 to 16,700 mature individuals is believed to be decreasing. The main threats are logging and conversion of habitat to agriculture. [1] It is considered rare to locally common, but " relatively little of the species’ habitat lies within protected areas". [3]
The Hispaniolan hutia is a small, endangered, rat-like mammal endemic to forests on the Caribbean island of Hispaniola. It lives in burrows or trees, and is active at night when it feeds on roots and fruits. A member of the hutia subfamily (Capromyinae), it is endangered from habitat loss and introduced species, such as rats or mongoose.
The Antillean palm swift is a species of bird in subfamily Apodinae of the swift family Apodidae. It is found on the Caribbean islands of Cuba, Jamaica, and Hispaniola.
The golden swallow is a swallow endemic to the Caribbean island of Hispaniola and was once native to Jamaica, but is now extirpated there. It is restricted to isolated montane forests that primarily consist of the Hispaniolan pine. This species is considered to be a vulnerable species by the International Union for Conservation of Nature (IUCN). The exact cause of its extirpation from Jamaica is unknown, but likely factors include predation by introduced mammals and habitat loss, although the habitat loss theory is not supported by much evidence. The last sighting of the nominate subspecies was in Hardwar Gap, with three birds being seen on 8 June 1989.
The tawny-faced quail is a species of bird in the family Odontophoridae, the New World quail. It is found in Colombia, Costa Rica, Ecuador, Honduras, Nicaragua, and Panama.
The least poorwill or least pauraque is a species of nightjar in the family Caprimulgidae, and the only confirmed extant species of its genus. It is endemic to the island of Hispaniola, which is shared by the Dominican Republic and Haiti.
The Hispaniolan lizard cuckoo is a species of bird in the tribe Phaenicophaeini, subfamily Cuculinae of the cuckoo family Cuculidae. It is endemic to the island of Hispaniola that is shared by Haiti and the Dominican Republic.
Calyptophilus is a genus of bird formerly placed in the family Thraupidae. The group was found to be distinct enough to be placed in its own family, Calyptophilidae. Established by Charles Barney Cory in 1884, it contains the following species:
The gray-barred wren is a species of bird in the family Troglodytidae. It is endemic to Mexico.
The green-tailed warbler, also known as the green-tailed ground-tanager, is a species of bird of the family Phaenicophilidae, the Hispaniolan tanagers. It is endemic to the island of Hispaniola which is shared by Haiti and the Dominican Republic.
The black-crowned tanager or black-crowned palm-tanager is a species of bird of the family Phaenicophilidae, the Hispaniolan tanagers. It is endemic to the island of Hispaniola which is shared by Haiti and the Dominican Republic.
The grey-crowned tanager or grey-crowned palm-tanager is a Near Threatened species of bird in the family Phaenicophilidae, the Hispaniolan tanagers. It is endemic to the Caribbean island of Hispaniola, in both the Dominican Republic and Haiti.
The pilotbird is a species of passerine bird in the family Acanthizidae. It is monotypic within the genus Pycnoptilus. The species is endemic to south-eastern Australia.
