The Mato Grosso floor Ameisenwürger ( Clytoctantes atrogularis ), also called Rondoniaverkehrtschnabel called, is a little-known bird art from the family of ants birds . It is endemic to the Brazilian state of Rondônia .
description
The Mato Grosso ground ant shrike reaches a length of 17 centimeters. The males are uniformly black, the females are reddish-chestnut-colored with a black breastplate. The striking, massive beak with an upwardly curved lower beak and a straight beak ridge is characteristic of the species. Its call consists of loud tree-tree-tree trills.
Way of life and habitat
Very little is known about his way of life. Its habitat is the terra-firme rainforest , which is dominated by dense vine roots. When foraging for food, he stays two to five meters above the ground.
status
After the discovery of a female in 1986 in the Terra typica near Ji-Paraná in Rondônia and a presumed sighting of a male near Alta Floresta in Mato Grosso in 1989, the species was initially lost. In 2004 a couple was observed on the Rio Sucunduri , Amazonas and in May 2006 another couple in the Reserva Biológica do Jarú near Ji-Paraná, Rondônia and their singing was recorded. While BirdLife International estimated the population at fewer than 50 specimens in 2005, recent observations by ornithologists Dante Buzzetti and Bret M. Whitney in 2006 and 2007 have shown that the species is more common than previously thought.
The main threats are the expansion of agriculture, road construction and commercial deforestation of the rainforest. The forest in the Terra typica is endangered by the construction of a dam.
