The Honduran Macilia ( Amazilia luciae , Syn . : Polyerata luciae ) is a rare hummingbird species from the genus Amazilia hummingbirds . Their occurrence is limited to a very small area in Honduras .
description
The Honduran macilia reaches a length of nine to ten centimeters. The male has a medium-sized straight beak. The upper beak and the tip of the beak are blackish, the lower beak reddish. The top is golden green. The tail covers have a bronze-green tinge. The throat and chest are glittering turquoise green to blue green. The flanks are green, the middle of the abdomen is grayish. The under tail-coverts are whitish at the edges and brownish in the middle. The slightly forked tail is light bronze green with a purple-black subterminal band on the outer control feathers. In the female, the throat shows more grayish areas and the turquoise color is paler. The outer control springs have gray tips. The immature birds resemble the females. The control springs have tan-colored tips.
habitat
The Honduran Mazilie lives in dry thorn forests and bushland at altitudes of 75 - 1,220 m. The thorn forest at Coyoles is about six to ten meters high and is dominated by cacti, milkweed plants and mimosa plants.
Way of life
The Honduran macilia feeds on the nectar of various flowers, including the genera Pithecellobium , Aechmea , Pedilanthus, and Stenocereus . It also catches insects in flight. Brooding hummingbirds have been seen in June. The clutch consists of two eggs.
status
The Honduran macilia was thought to be lost twice. Once between 1867 and 1937 and then between 1950 and 1988. Until then, only 11 museum specimens from six different sites from Santa Bárbara, Cofradía, the Guayape Valley and Catacamas were known. In June 1988 the species was rediscovered near Olanchito and Coyoles in the upper valley of the Río Aguán in the Yoro department . In 1991, 22 to 28 specimens were observed at Olanchito. In 1996 a population was discovered northeast of Gualaco in an area of less than 1 km² in the Agalta Valley. The Honduran Amazilie has disappeared from the regions near Santa Bárbara, Cofradía and in the Guayape Valley. The thorn forest has been replaced by cattle pastures and the few extremely dry thorn forest fragments only provide a habitat for a few birds. Today between 250 and 1000 specimens live in the thorn forests in the Río-Aguán and Agalta valleys. These habitats are also threatened by conversion into rice and pineapple plantations.
Etymology and history of research
The first description of the Honduran Mazilie was in 1868 by George Newbold Lawrence under the scientific name Thaumatias Luciæ . The type specimen came from Honduras. Only later was it added to the genus Amazilia . This name comes from a novella by Jean-François Marmontel , who reported in Les Incas, Ou La Destruction De L'empire Du Pérou, about an Inca heroine named Amazili. "Luciae" is dedicated to Lucy Stone Brewer (1854–1921), a daughter of Thomas Mayo Brewer (1814–1880).
