( Sick , 1959)

The yellow-headed cipra ( Lepidothrix vilasboasi ) is a species of bird from the purr family , which is only known from two areas in the southwestern part of the Brazilian state of Pará .

features

The yellow-crowned pipra reaches a length of 8.5 centimeters. The male has a glittering greenish-gold crown and neck. The lower back and the upper tail-coverts are greenish-yellow. The rest of the head and top are green. The hand and arm feathers as well as the tail feathers are predominantly black with broad greenish edges. The area from the chin to the chest is green. The belly and under tail-covers are yellowish. The iris is light gray. The beak is light bluish. The legs are pink-flesh-colored. The female looks similar to the male, with the apex showing a slightly bluish tint and both the top and the area around the rump being greenish. The voice is a whirring “ prreee ” that sometimes sounds in rows.

Occurrence and habitat

The distribution area of ​​the yellow-crowned pipra is limited to the area of ​​the upper Río Cururu-rí, a tributary of the Rio Tapajós in the Serra do Cachimbo, and to the region of Consórcio Jamunxim in the southwestern part of the Brazilian state Pará . The habitat are moist forests at altitudes up to 200 m.

Way of life

The yellow-headed pipra feeds on small fruits and insects. No more is known about his way of life.

Systematics

The yellow-headed pipra was described as a valid species by Helmut Sick in 1959 . However, a 2017 study concluded that this taxon was a hybrid reproductive species. 80 percent of the genome comes from the opal tip pipra ( Lepidothrix iris ) and 20 percent from the white rump pipra ( Lepidothrix nattereri ).

status

The yellow-headed pipra was discovered in 1957 by Helmut Sick on the upper reaches of the Río Cururu-rí and described on the basis of five specimens. Thereafter, the species remained lost until a male was rediscovered in May 2002 on the Río Jamunxim near Novo Progresso, about 200 km from the Terra typica . The site on the Río Cururu-rí is within the 400,000 hectare Mundurucânia Forest Reserve, which is privately owned by the Brazilian Air Force and is strictly protected. Access is restricted and logging is prohibited. The second site on the Río Jamunxim was cleared due to the construction of the BR 163 Cuiabá-Santarém road. In 2006, two courtship arenas were discovered in a selectively cleared forest area, about 20 km from the area from 2002. The extent of deforestation in the Terra typica area is unknown, but livestock is practiced in the region. The area near Novo Progresso is under enormous pressure from the increasing demand for pastureland and is one of the regions in the Amazon most threatened by deforestation. Due to the paving of the BR 163 Cuiabá-Santarém road and the increase in traffic to Santarém due to the opening of the soy markets, it is feared that the future of habitat will be even more severe. BirdLife currently estimates the population of the yellow-headed cipra at between 2500 and 10,000 specimens and classifies the species as endangered .
