Many-coloured Rush Tyrant (Tachuris rubrigastra)


Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Passeriformes
Family : Tyrannidae
Genus : Tachuris
Species :
T. Rubrigastra


Description:

The Many-coloured rush tyrant (Tachuris rubrigastra) or Many-colored rush tyrant is a small passerine bird of South America belonging to the tyrant flycatcher family. It is the only member of the genus Tachuris and its relationships with the other members of the family are uncertain. It inhabits marshland and reedbeds around lakes and rivers. It is particularly associated with stands of Scirpus. The nest is built among plant stems.

There are four subspecies: T. r. rubrigastra is the most widespread, occurring from south-east Brazil to southern Argentina and central Chile. T. r. alticola is found in the Andes of south-east Peru, west Bolivia and north-west Argentina. T. r. libertatis is found in coastal Peru while T. r. loaensis is restricted to Antofagasta Region in northern Chile.

It is a small bird, 10.5 cm in length. The tail is short, the wings are short and rounded and the bill is slender. As the bird's name suggests, the plumage is very colorful. The back and rump are green while the underparts are yellow apart from the white throat, black breastband and red undertail-coverts. The face is dark blue-grey, there is a yellow stripe over the eye and the crown is dark with a red patch that is often concealed. The wings and tail are dark with a white wingbar and white outer tail-feathers. Juveniles are considerably duller than the adults.

ANIMALS – BIRDS – SONGBIRDS – VERMILION FLYCATCHER (PYROCEPHALUS RUBINUS)


Animals - Birds - Songbirds

Vermilion flycatcher (Pyrocephalus rubinus)


Scientific Classification:

Kingdom : Animalia
Phylum : Chordata
Class : Aves
Order : Passeriformes
Family : Tyrannidae
Genus : Pyrocephalus
Species :
P. Rubinus


Description:

The Vermilion flycatcher (Pyrocephalus rubinus) is a small passerine bird in the Tyrannidae, or tyrant flycatcher family. Most flycatchers are rather drab, but the vermilion flycatcher is a striking exception. It is a favorite with birders, but is not generally kept in aviculture, as the males tend to lose their vermilion coloration when in captivity.

When Pieter Boddaert first described the vermilion flycatcher in 1783, from a specimen collected in Tefé, Brazil, he assigned it to the genus Muscicapa, believing it to be related to the many Old World flycatchers already belonging to that genus. By the 1830s, however, taxonomists realized that Old World and New World flycatchers were not closely related, and the New World birds were moved from their former genera. In 1839, John Gould created the current genus Pyrocephalus for the vermilion flycatcher. While it is considered a monotypic genus by many authorities, some taxonomists believe that one or both of the vermilion flycatcher subspecies found on the Galápagos Islands merit species status.

There are 12 widely recognized subspecies, which differ primarily in the color and saturation of the male's plumage and the color and amount of streaking of the females. The boundaries between some of the subspecies are not well defined.

The vermilion flycatcher is a small bird, measuring 13–14 cm (5.1–5.5 in) in length, with a mass between 11 and 14 g (0.39 and 0.49 oz). It strongly dimorphic; males are bright red, with dark brown plumage. Females have a peach-colored belly with a dark gray upperside, and are similar to Say's phoebe.

Name : Pyrocephalus rubinus
Taxonomist : Pieter Boddaert (Middelburg - Netherlands)
Year :
1783

12 (Ardens, Blatteus, Cocachacrae, …)
