features

The Jamaican mango libri reaches a body length of about 11 to 12 cm, with a weight of 8.5 to 9.1 g. It is a medium-sized dark hummingbird that is slightly different from other species in the genus Anthracothorax . The male has a slightly curved black bill. The top of the head looks washed out green. The side of the head and neck is metallic magenta violet. The underside is velvet black, the back is matt green bronze. The central control springs are dark bronze to dark black. The rest of the tail is metallic purple with a narrow dark blue band. The female resembles the male, but has washed-out velvet green flanks. The outer control springs have white tips. Immature males have a deep blue collar patch that turns into velvet in the second year of life.

Behavior and nutrition

The Jamaican Mangokolibri gets its nectar from a variety of flowers that suit the needs of the bird. These can be both native and introduced species. The plants he flies to include species of the genera Hohenbergia , Opuntia , Stenocereus , Kordien , Tabebuia , Spathodea and Bauhinien . Males defend their food territory on mass-flowering trees . This includes arthropods , which it catches in flight for its food. It often prey on them at 10 to 15 meters above the ground.

Reproduction

Jamaican mango nests exist year-round, but most appear to be between January and May. The nest is a small goblet made of dense woven silk fibers, such as seeds. B. of Tillandsia and cobwebs. He attaches this to a thick branch in the tree 3 to 8 meters above the ground. A clutch consists of two white eggs that are only hatched by the female. The chicks are blackish, with two grayish stripes on their backs. There is only one brood per season.

Vocalizations

The Jamaican mango ribri is considered a rather quiet contemporary. His singing has not yet been described. He makes sharp, scratchy tik..tik..tik .. sounds.

distribution and habitat

The Jamaican mango tibri has a wide range of habitats in which it moves. They include open to semi-open lowland vegetation including dry areas, gardens and plantations. It is often found along the edges of the forest at altitudes from sea level to 800 meters. Regularly or rarely, with the exception of the months June to August, he is on the move at medium altitudes on natural edges, more humid and in elven forests at altitudes between 900 and 1500 meters. He avoids mangroves .

From June to August, the Jamaican mango cibri moves to the middle altitudes of Cockpit Country or the Blue and John Crow Mountains National Park . This happens after the end of the flowering period at higher altitudes.

Etymology and history of research

The first description of the Jamaican mango was in 1758 by Carl von Linné under the scientific name Trochilus Mango . The type specimen came from Jamaica. Friedrich Boie introduced the genus Anthracothorax as early as 1831 . 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 »mango« may have come about through a mistake by Eleazar Albin. Eleazar Albin described the bird as the Mango Bird in 1731 and thought it was the Jamaican Mango Bird . Later it turned out that it was this name is the Indian oriole ( Oriolus kundoo Sykes , 1832) could act.

Remarks

  1. ↑ Boie arranged the genus the Jamaica Mango Hummingbird ( Anthracothorax mango ( Linnaeus , 1758)), the blue star Antilles Kolibri ( Eulampis holosericeus ( Linnaeus , 1758)), Purple Kehl Kolibri ( Eulampis jugularis ( Linnaeus , 1766)) (Syn: Trochilus violaceus ), Smaragdkehl- Mangokolibri ( Anthracothorax viridigula ( Boddaert , 1783)) (Syn: Trochilus gramineus ) belonging to the genus.
  2. ↑ Whether the theory is correct can at least be doubted. I.a. the authors doubt that Eleazar Albin really was in Jamaica in 1701. But they did not take into account that Eleazar Albin was still called Eleazar Weiss at the time. Not much is known about Eleazar Albin's early days. The origin of the word could also be found in the Taíno language . For example, there is an archaeological region of Taíno in Cuba called Potrero de El Mango.
