Braunwangensittich

Bestimmung

The brown-throated parakeet is 23 to 28 cm (9.1 to 11 in) long and weighs 76 to 102 g (2.7 to 3.6 oz). The sexes are alike. Adults of the nominate subspecies E. p. pertinax have a yellow forehead, face, and chin. Their crown, nape, and upperparts are green. Their breast is dull olive and their belly grass green with an orange patch in its center. Their wings are mostly green with dullish blue edges and tips on the flight feathers; their tail feathers are also green with dullish blue edges and tips. Immature birds have very little yellow.<p>The other subspecies differ from the nominate thus:

Taxonomie

The brown-throated parakeet was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus pertinax. The brown-throated parakeet is now one of five species placed in the genus Eupsittula that was introduced in 1853 by the French naturalist Charles Lucien Bonaparte. The genus name combines the Ancient Greek eu meaning "good" with the Modern Latin psittula meaning "little parrot". The specific epithet pertinax is Latin meaning "tenacious" or "persistent".<p>These 14 subspecies are recognized; some of them are island endemics: <p>Subspecies E. p. ocularis has sometimes been treated as a separate species, the "Veraguas parakeet".

Verbreitung und Lebensraum

The subspecies of the brown-throated parakeet are found thus:<p>The nominate subspecies of the brown-throated parakeet was introduced in Saint Thomas, U.S. Virgin Islands and was established by the 1860s. From there it spread to Culebra Island, Tortola, and Puerto Rico but had been extirpated from them by about 1982. More recent sightings in Puerto Rico and those in Florida, the British Virgin Islands, Anguilla, Dominica, and San Andrés are known or suspected to be of escaped or released cage birds rather than deliberate introductions or natural arrivals.<p>The species is a non-breeding visitor to Trinidad.<p>The brown-throated parakeet inhabits a wide variety of landscapes including savannas, arid scrublands, mangroves, tropical deciduous forests, gallery forests, evergreen forests, and cultivated areas and pastures with some remaining trees. In Colombia, it reaches an elevation of 2,600 m (8,500 ft) but is found mostly below 1,200 m (3,900 ft) elsewhere. It is also widely distributed in Venezuela, but shows preference for areas with open vegetation with higher probabilities of occurrence in the savannas of the Llanos bioregion and the arid scrublands of northwestern Venezuela.
