The emerald mango ( Anthracothorax viridis ) or emerald mango is a species of bird in the hummingbird family (Trochilidae) that is endemic to Puerto Rico . The IUCN assesses the population as Least Concern . The species is considered to be monotypical .
features
The Emerald Mangocolibri reaches a body length of about 11 to 14 cm, with a weight of 7 g. The sexes are very similar. It has a slightly curved black beak. The top is emerald green, the bottom metallic blue-green. The rounded tail is metallic blue-black. Adult females have a small white eye spot that males do not. Immature birds have brownish fringed feathers on their head and back.
Behavior and nutrition
The Emerald Mangocolibri gets its nectar from blossoms in blooming trees, scrub and tendrils, such as B. Pariti tilaceum , Leonotis leonotum , Quisqualis indica and plants of the genus of Morningglory . This includes insects that it catches in flight for its food. He often preyed on them above the treetops. Another important source of protein are spiders, which it collects from the surface of leaves. He vomits indigestible chitinous feed in pellets. He looks for his food in the strata from the deep undergrowth to the treetops. Males defend their food territory on flowering trees .
Reproduction
The breeding season is at least from October to May. The nest is a soft, compact chalice that is decorated with lichen on the outside. He attaches this to vertical branches in tall trees, which are usually over 8 meters above the ground. A clutch consists of two white eggs. The chicks are black with two stripes on the back. There is only one brood per season.
Vocalizations
The emerald mango libri is considered a rather quiet contemporary. His singing involves repeated high phrases that begin with a sluggish buzz as stsss STSI STSI tschup STSI stri ... sounds. Lutes also contain repeated short tsik tones and light, chirping hums. In hostile situations, it emits loud, sharp rattles and chatter sounds.
distribution and habitat
The emerald mango tibri prefers the plantations and forests in the central and western mountains of Puerto Rico. It is also very rarely seen in the coastal areas. Mostly he is on the move at altitudes of 800 and 1200 meters.
migration
The emerald mango tibri is considered to be a line bird that migrates at high altitudes, depending on the flowering season.
Etymology and history of research
The first description of the emerald mango colibris was in 1801 by Jean Baptiste Audebert and Louis Pierre Vieillot under the scientific name Trochilus viridis . The type specimen came from the northern islands of America and was made available to the authors by René Maugé . Friedrich Boie introduced the genus Anthracothorax as early as 1831 . It was not until later that the emerald mango was assigned to the genus. This name is derived from the Greek "anthrax, anthrakos ανθραξ, ανθρακος " for "coal, precious being" and "thōrax, thōrakos θωραξ, θωρακος " for "breast". The species name "viridis" is the Latin word for "green".
