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.

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".
