The Short-billed Nektarjala ( Neodrepanis hypoxantha ) is endemic to Madagascar occurring bird from the family of asity (Philepittidae).

features

The very small short-billed nectar jalas reach a body length of 9.0 to 10.0 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 green on the inside and has a blue border. Throat, chest, belly and flanks are bright yellow, the rest of the plumage is blue-gray. During the rest of the time, they wear a plain dress in which the head plumage, the back plumage and the wings are olive green. The female shows a very similar drawing all year round.

Similar species

The long-beaked nectar jala ( Neodrepanis coruscans ) has a slightly longer beak. The wings of the males show strong blue tones in their splendid dress; the eye skin flap is light blue and has no green color elements. In the plain dress and in the females, dark olive tones predominate in the plumage on the upper side.

distribution and habitat

The distribution area of ​​the short-billed nectar jala extends along the entire east side of Madagascar. It prefers to colonize rainforests and areas with shrub vegetation at higher altitudes. It has been detected even at an altitude of 2,650 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). Occasionally, insects are also accepted as food. Short-billed nectar jalas can sometimes be seen in mixed flocks of birds. The main breeding season falls from November to January. The nest is made by the female from dry leaves and moss and laid out in the foliage with a small canopy over the entrance two to three meters above the ground and equipped with two eggs. Details on the breeding behavior are not available.

Danger

The short-billed nectar jala occurs sparsely in the national parks and the adjacent areas in eastern Madagascar. Therefore, a significant genetic exchange between the populations is not sufficiently ensured. The species is also threatened by the reclamation of previous habitats and by uncontrolled forest fires. It is therefore classified by the World Conservation Organization IUCN as VU IUCN 3 1st svg" vulnerable = endangered".
