The Elliotelfe ( Atthis ellioti ) is a species of bird from the hummingbird family (Trochilidae) that occurs in Mexico , Guatemala , El Salvador and Honduras . The IUCN assesses the population as Least Concern .

features

The Elliotelfe reaches a body length of about 6.5 to 7.6 cm, with a weight of about 2.0 and 2.6 g. The male has a short straight black beak. The top is green with a white streak behind. The ear covers are grayish. The throat shimmers pinkish-pink. The rest of the underside is whitish, the flanks cinnamon-colored with green speckles. The central control feathers of the rounded tail are green and turn reddish-brown away from the body. The rest is reddish-brown with a black subterminal band. The outer control feathers are spotted white to washed-out cinnamon. The female resembles the male on the upper side but has only a small white point behind the eye. The throat is whitish with gray spots. The underside is white, the flanks and the underside of the tail are cinnamon-colored. The double-lobed tail is similar to that of the male. Fledglings resemble females in terms of coloration, but young males have some pink spots on their throats.

Behavior and nutrition

Presumably the Elliotelfe gets its nectar from plants similar to the rose throat elf . She visits coral trees , opuntia , sage , the species Cuphea jorullensis , which belongs to the quiver flowers , the species Penstemon perfoliatus and Penstemon gentianoides , which belongs to the beard thread, and the species Tigridia orthantha, which belongs to the tiger flowers . It also feeds on small arthropods . It does not establish a feeding ground and is subservient to other larger hummingbird species. Her bumblebee-like behavior enables her to get hold of nectar without attracting the attention of other species.

Vocalizations

The Elliotelfe singing is a sustained songbird-like warble that includes several different tones and short acts of singing. She emits these at different pitches, repeating them several times before switching to the next note. Some notes sound lively, other whistles thin, and still others like chirping notes. The call contains chip or sip tones, which are often doubled or end in short chatter.

Reproduction

Little is known about the reproductive behavior of the Elliotelfe. One report said a nest was discovered in Guatemala in August with two chicks one meter above the ground. Neither the nest nor the chicks were described in detail. It could be that the males meet at leks for courtship .

distribution and habitat

Distribution area (green) of the Elliotelfe

Elliotelfen prefer to move around moist to semi-moist forest edges, in pine and oak forest areas and clearings at 1500 to 3500 meters above sea level. The foraging takes place from the low to the middle strata . Adriaan Joseph van Rossem and Donald Ryder Dickey reported in 1838 about a specimen on the Santa Ana volcano in El Salvador .

migration

The Elliotelfe is considered a standing bird .

Subspecies

So far, two subspecies are known:

  • Atthis ellioti ellioti Ridgway , 1878 occurs in southern Mexico and Guatemala.
  • Atthis ellioti selasphoroides Griscom , 1932 occurs in Honduras. The male of the subspecies is yellow-brown on the underside, the white spots on the tail feathers have been replaced by yellow-brown. The subterminal band is wider.

Etymology and history of research

The Elliotelfe was first described in 1878 by Robert Ridgway under the scientific name Atthis ellioti . The type specimen comes from the collection of Daniel Giraud Elliot and was shot on the Volcán de Fuego . Ridgway had received another copy from Adolphe Boucard of Mexico. In 1854 the new genus Atthis was introduced by Heinrich Gottlieb Ludwig Reichenbach for the rose-throated elf ( Atthis heloisa ( Lesson, RÜ & Delattre , 1839)). " Atthis " was a daughter of Kranao and the mistress of Sappho . The species name »ellioti« is dedicated to its collector. »Selasphoroides« is a Greek word formation from »selas σελας, σελατος « for »light, fire, flame«, »-phoros, pherō -φορος, φερω « for »carrying, carrying« and »-oidēs -οιδης « for »resembling, equal «.
