The yellow-rump leaf tyrant ( Phylloscartes roquettei ) is a rare passerine bird from the tyrant family . It is endemic to the Brazilian state of Minas Gerais . The species is named after the Brazilian ethnologist Edgar Roquette-Pinto .
description
The yellow rump leaf tyrant reaches a length of 11.5 cm. Its plumage is predominantly olive green. The forehead and reins are bright red. Faint yellow bands can be seen in the area of the wings. The underside is light yellow, the throat is characterized by a strong yellow color. The tail is slightly erect and narrow. His singing consists of a rapidly chirping pr'r'r'r 'it tit-tit-tit and sharp beeps.
Way of life
The yellow rump leaf tyrant prefers semi-arid woodland and gallery forests , which are characterized by medium moisture conditions. In the dry forests as well as in the gallery forests, it can be found on the upper branches of tall, young trees that serve as a seat guard for insect hunting.
status
The yellow-rump leaf tyrant was discovered near Januária in Minas Gerais in July 1926 . The second proof was made in 1977 on both sides of the Rio São Francisco . After unsuccessful searches in 1985, 1986 and 1987, a few specimens were observed in 1993 near Várzea da Palma , near Pirapora (about 190 km south of the Terra typica ). A male was collected from Francisco Dumont (about 250 km south of the Terra typica) in 1995 . After searches in 1998, 1999 and 2002, the organization BirdLife International estimates the population at 50 to 250 specimens and classifies the species in the “critically endangered” category. The habitat of the yellow-rump leaf tyrant is heavily fragmented due to clearing. Charcoal extraction , agricultural use, limestone mining in the Rio São Francisco basin and a large-scale irrigation project pose additional hazards .
