The fire-throated elf ( Selasphorus ardens ) or ember- throated hummingbird is a species of bird in the hummingbird family (Trochilidae) that is endemic to Panama . The stock is on the IUCN as endangered ( Endangered estimated). The species is considered to be monotypical .
features
The fire throat elf reaches a body length of about 7 cm. Adult animals have a short, straight black beak. The male is bronze green on top. The control feathers are black with reddish brown borders and smaller notches. The outer hand wings are a little weaker. The ring collar is lilac red and borders the white collar band in the front neck area. The central area of the chest and belly are white, the rest of the underside is yellow-brown to cinnamon in color and decorated with a little green. The under tail-coverts are yellow-brown to white. Females are similar to males, but the throat is pale yellow-brown with green flecks. The central control feathers are mostly green, but laterally red-brown at the base with a black subterminal band and strong yellow-brown tips. Fledglings are similar to adult females, but have rust-colored fringes on the top of the head and neck and a little more green on the two central pairs of tail feathers.
Behavior and nutrition
There are no reliable data on the diet of the fire-throated elves. It is assumed that this is very similar to that of the orange-throated elf ( Selasphorus scintilla ( Gould , 1851)).
distribution and habitat
The fire-throated elf prefers the forest edges of the mountains in western central Panama from Ngöbe-Buglé and the Veraguas province . Here it moves at altitudes of 750 to 1800 meters.
Etymology and history of research
The fire-throated elf was first described in 1870 by Osbert Salvin under the scientific name Selasphorus ardens . The type specimen was collected by Enrique Arcé near Calovébora and Castillo. In 1831 William Swainson introduced the new genus Selasphorus . This word is derived from the Greek words "selas σέλας " for "shine, light, flame" and "-phoros, pherō πηοροσ " for "supporting, carrier". The species name "ardens" is the Latin word for "burning, glowing" from "ardere" for "to burn".
