description

With a body length of up to 25 cm and a weight of 117 to 192 g, white- rump loris belong to the medium-sized loris . The species comes in a yellow and an orange color morph . Most noticeable are the color differences on the chest. Depending on the morphology, there are two more or less distinct reddish orange to yellow bands or a lower orange and upper yellow band, each separated by a wider dark brown band. Otherwise the plumage is predominantly dark brown, the feathers of the cheeks, neck and upper chest are lined with yellow. The rump is yellow-brown whitish, the short brownish-olive tail is rounded. There are orange spots on the inside flags of the lateral tail feathers, the under tail feathers are more yellowish on the outside flags . The central tail feathers are orange and lined with broad purple-brown at the tips. The under tail-coverts are black-violet. The wings are dark brown with a purplish tinge, the innermost large covers and umbrella feathers are tinged with orange-red. There is an orange spot on the bow of the wing. The outer flags of the hand wings are lined with olive color, the yellow or orange coloring of the inner flags forms a band over the center of the upper and lower wings. The under wing coverts are tinged with yellow or orange. The flanks are dark brown, the trousers reddish in both color morphs.

The beak and the featherless skin at the base of the beak are orange in color. The iris is red, the orbital ring is brown. The legs are dark gray. The sexes are similar to each other. Juvenile animals are less clearly banded underneath, they generally appear more dull and more uniformly colored. Their bill is brownish black with a yellowish base on the lower mandible, their irises are yellowish gray.

distribution and habitat

With the exception of the highest altitudes in New Guinea as well as on the island of Yapen ( Cenderawasih Bay , formerly Geelvink Bay ) and on the island of Salawati off the coast of western New Guinea . They live in mountain rainforests , in and on the edge of forests, secondary forests , parks, gardens and on plantations at altitudes of up to 2,400 m.

Way of life

Whitebacked Loris are very sociable animals, they often form large, loud, soaring swarms. The swarms scream incessantly and can be heard from afar, their screams should sound like "a horde of angry giant cicadas ". They depend on flowering trees for their food and are therefore heavily migrating. They feed on flowers ( nectar , possibly pollen ) and occasionally on fruits and insects. Their nest is in high, tall trees. It is incubated for around three weeks, and the young are fledged after around 72 days.

Subspecies

Pseudeos fuscata incondita ( Meyer, AB , 1886) has long been considered a subspecies. Today, however, the species is considered monotypical .

Etymology and history of research

Edward Blyth described the white-eared lory under the name Eos fuscata . He was unable to provide any information about the location of the type specimen . It was not until 1935 that James Lee Peters introduced the new generic name Pseudeos for the white- eared lory . The name is derived from the Greek words "pseudos ψευδος " for "false" and "eōs εως " for "east, orient". Fuscata is derived from the Latin »fuscatus, fuscare, fuscus« for »dark, darken, black«. Incondita is derived from the Latin "inconditus" for "inconsistent, confused, disordered".
