The rose- tailed trogon ( Harpactes wardi ) is a species of bird from the trogon family , whose distribution extends from northeast India to western Yunnan and northern India . It is one of the rarest trogons in Asia.

description

The rose tail trogon reaches a body length of 35–38 cm and a weight of 115–120 g. The sexes differ significantly. The male has a dark pink beak and a blue orbital ring . The head, chest and top are slate-colored with a reddish-brown tint. The forehead and the stripe above the eyes , like the underside and the outside of the tail, are colored red to dark pink. The female's beak is yellow with a black ridge. The head, breast and upper side are dark olive-colored, the red or dark pink areas of the male are yellow. The youth's dress of the male has not yet been described, that of the female is warmer in color on the upper side and shows less yellow on the forehead than in adult females.

voice

The vocal utterances consist of a series of calls of soft, faster kliu sounds, which are often accelerated a little towards the end and decrease in pitch. A sharp-sounding whirrur is also described.

Distribution and existence

The distribution of the rose-tailed trogon is limited to the eastern Himalayan region and the neighboring mountain regions to the east . It extends from Bhutan and northeast India through the north and east of Myanmar to western Yunnan ( China ) and Tonkin in northern Vietnam .

The rose tail trogon is one of the species of the endemic bird area "Eastern Himalayas" and is also found in the secondary area " Fan-Si-Pan and northern Laos". The very secret living species is mostly rare or very rare and was classified as "endangered" ( vulnerable ) in 1994 . After the discovery of fairly stable occurrences in Bhutan, it is now only on the IUCN's warning list ( near threatened ) .

Way of life

The rose tail trogon populates the lower strata , the undergrowth and bamboo stocks in larger subtropical mountain forests of oak and pseudo-chestnut as well as temperate , evergreen deciduous forests with creepers . The altitude distribution of the species is usually between 1500 and 3200 m, but it can also be found at lower altitudes down to 300 m. In winter it probably migrates to lower elevations.

The diet consists of insects such as butterflies , ghosts , grasshoppers and bed bugs . Berries are also part of the diet, and larger plant seeds (probably acorns) have been found in the stomach contents of one specimen. Other stomachs examined contained only insects - mostly quite large animals.

Observations that indicate broods were mostly between late March and early April. Nothing is known about the reproduction of the species.

Etymology and history of research

Norman Boyd Kinnear described the newly discovered trogon in 1927 under the name Pyrotrogon wardi . He received the type specimen from Frank Kingdon-Ward , to whom he also dedicated the specific epithet . The word "Harpactes" comes from the Greek word "harpaktēs ἁρπακτής " for "robbers".
