The Rosselwärupenfänger ( Edolisoma rostratum ) is a hardly researched songbird species from the family of the prickly pear family (Campephagidae). He is on the island of Rossel in Louisiade archipelago endemic .
features
The rose caterpillar catcher reaches a body length of 24 to 27 cm. The adult male is predominantly slate gray with a black face mask that extends from the throat to the ear covers. The flight feathers have dark centers and light edges. The adult female is bright brown. The elytra and wing feathers have dark centers. The skull and neck are a bit grayish-brown. The dark tail has yellow-brown corners. The rump is strongly banded in dark. The underside is yellow-brown. The sides of the neck and the chest are banded differently in black. The dark banding extends over the flanks and sides to the middle of the abdomen. The plumage of the juvenile and half-grown birds is apparently undescribed.
Systematics
The Rosselraupenfänger was described by Ernst Hartert in 1898 as an independent species Edoliosoma rostratum . Then it was considered a long time under the name Coracina tenuirostris rostrata as a subspecies of the thin-billed caterpillar catcher ( Edolisoma tenuirostre ). In 2016 it received species status again.
Habitat and way of life
The habitat is little explored. The species is likely restricted to forests and forest edge habitats , similar to other taxa of the Edolisoma tenuirostre species group. In 2004, one specimen was observed in a primary forest near gardens. The Rosselwatercatcher is a resident bird . Nothing is known about his way of life.
status
Since Albert Stewart Meek collected the type specimens in 1898, there was no evidence of this species until 2014. In December 2014, the ornithologist William Goulding succeeded in rediscovery when he was able to observe a specimen over a period of four days. The IUCN has listed the Rosselwatercatcher since 2016 in the category "insufficient data" ( data deficient ). Despite the small distribution area of 390 km² and the lack of inventory surveys, the population is considered stable. Between 2000 and 2014 the deforestation rate on Rossel was less than 5 percent.
