The tooth-billed wren ( Odontorchilus cinereus ) is a bird art from the family of wrens (Troglodytidae) located in Brazil and Bolivia is widespread. The IUCN assesses the population as Near Threatened . The species is considered to be monotypical .
features
The tooth-billed wren reaches a body length of about 12.0 cm with a weight of the male of about 11.0 g. The top of the head is cinnamon gray brown, the back and shoulders medium gray. The wings of the hand and the wings , on the other hand, appear a little darker. The control feathers are gray-brown with about six wide grayish black bands. The outermost control springs have light-colored tips. The ear covers are gray-brown, the throat and chest yellow-brown-gray and the flanks grayish white. The under tail-coverts are grayish white with blackish gray bandages. The eyes are dark brown to brick red, the beak black with a gray base on the lower beak. The legs are dark gray. Both sexes are similar. Young animals are brownish in color at the base of the lower mandible.
Behavior and nutrition
Little data is known on the food of the tooth-billed wren. Most likely it feeds on invertebrates . He looks for his food in the upper strata of the forest canopy. He regularly mingles with groups with tyrants , tangerines and pottery birds .
Vocalizations
The Toothbill Wren's song consists of a loud series of notes at the same altitude. This is slower and less warbled than is the case with the gray- coat wren . The call includes a high- pitched sui tone.
Reproduction
The breeding biology of the tooth-billed wren is almost unexplored. In Bolivia at the beginning of September a female was observed in a breeding mood.
distribution and habitat
The tooth-billed wren prefers the forests of the tropical lowlands. Here it occurs at altitudes between sea level and 500 meters. It is distributed in central Brazil south of the Amazon in the eastern area of the state of Amazonas and in Pará further south to the south of Rondônia and central Mato Grosso as well as eastern Bolivia in the northeast of the Santa Cruz department .
migration
The tooth-billed wren is probably a resident bird , without any further data on the bird's migratory behavior are known.
Etymology and history of research
The first description of the tooth-billed wren in 1868 by August von Pelzeln under the scientific name Odontorhynchus cinereus . The type specimen was collected by Johann Natterer (1787–1843) at Salto do Girão . In 1915 Charles Wallace Richmond introduced the genus Odontorchilus, a new genus for science, for the tooth- billed wren, as Odontorhynchus was already documented by Odontorhynchus Leach , 1830. This name is derived from "odous, odontos οδους, οδοντος " for "tooth" and "orkhilos ορχιλος " for "wren". The species name "cinereus" is the Latin word for "ash gray" from "cinis, cineris" for "ash".
