The Long-billed Nektarjala ( Neodrepanis coruscans, also pseudo Sunbird ) is endemic to Madagascar occurring bird from the family of asity (Philepittidae).

features

The very small long-billed nectar jalas reach a body length of 9.5 to 10.5 centimeters. The control springs are very short. The beak is long and curved and therefore very suitable for taking in nectar from flowers. Between the sexes there is at times a clear sexual dimorphism in terms of plumage color . Only the males present during the courtship - a colorful plumage (and breeding season plumage ). You then have a black colored head. There is a flap of skin around the eyes that is light blue in color. The throat, chest, belly and flanks are bright yellow, the dorsal plumage is blue-gray, the wings blue to gray-green. During the rest of the time, they wear a plain dress in which the head plumage as well as the back plumage and the wings are mostly dark olive green. The female shows a very similar drawing all year round.

Similar species

The short-beaked nectar jala ( Neodrepanis hypoxantha ) has a slightly shorter beak. The wings of the males show gray-blue tints in the plumage of the magnificent dress; the eye flap is green on the inside and has a dark blue border. In the plain dress and in the females, matt olive tones predominate in the plumage on the upper side.

distribution and habitat

The distribution area of ​​the long-beaked nectar jala extends along the entire east side of Madagascar. It prefers to colonize rainforests at altitudes between 400 and 1500 meters.

Way of life

The birds feed primarily on nectar, for example the flower nectar of Bakerella , balsam ( Impatiens ) Hedychium - black mouth plant (Melastomataceae) and red plant species (Rubiaceae). The food spectrum is occasionally by the nectar of luster herb ( Lipari ) from the family of orchids (Orchidaceae) and by small fruits or insects expanded. Sometimes long-billed nectar jalas can be seen in mixed flocks of birds. The main breeding season falls from August to January. The egg-shaped nest is made by the female from dry leaves, slender twigs and moss and is laid out in the foliage with a small canopy over the entrance at a height of about five meters above the ground and equipped with two eggs. Both parents provide the nestlings with food. Further details on the breeding behavior are not available.

Danger

The long-billed nectar jala is widespread and not uncommon in the eastern national parks and the adjacent areas in Madagascar. It is therefore classified by the World Conservation Organization IUCN as LC IUCN 3 1st svg“ least concern = not endangered”.
