The Andean crested ear ( Pseudocolaptes boissonneautii ), sometimes also called white-cheeked prey , is a species of bird from the family of the potter birds (Furnariidae). The species has a large range that covers about 390,000 square kilometers in the South American countries Venezuela , Colombia , Ecuador , Peru, and Bolivia . The IUCN assesses the population as Least Concern .
features
The Andenschopfohr reaches a body length of about 20 to 21.5 centimeters. The straight black beak becomes about 20 millimeters long. The upper part of the plumage is brown. The crown is a little darker. The back is traversed by yellow-brown stripes. The wings have a red-brown border. The rump and tail are bright red-brown. The throat is white. The feathers on the side of the neck are longer and form a conspicuous, snow-white tuft. The chest is white with brown stripes and turns reddish yellow towards the abdomen and reddish brown on the lower rump (crissum). The beak length can vary slightly depending on the subspecies and gender.
Habitat
The bird moves mainly in the middle and upper canopy of moist mountain forest. It can be seen at altitudes between 1700 and 3450 meters. When searching for food, he likes to move on long horizontal branches. Here you can see it on bromeliads and epiphytes .
behavior
The bird can be alone or accompanied. He also changes his companions. Mostly he flies high and avoids proximity to the ground. Sometimes it supports itself with its tail downwards, makes a lot of noise or rummages through the area. He likes to climb moss and epiphytes to eat. The Andes' Crested Ear feeds mainly on insects and their larvae, but small frogs also represent part of the food spectrum. It finds food in bromeliads, mosses, lichens and other epiphytes. This explains the proportion of small frogs in its food spectrum, as their habitat is the accumulations of water in the epiphytic funnel bromeliads.
Subspecies
So far, nine valid subspecies have been described for the species.
- Pseudocolaptes boissonneautii auritus ( Tschudi , 1844)
- Pseudocolaptes boissonneautii boissonneautii (Lafresnaye, 1840)
- Pseudocolaptes boissonneautii carabayae ( Zimmer , 1936)
- Pseudocolaptes boissonneautii intermedianus ( Chapman , 1923)
- Pseudocolaptes boissonneautii medianus ( Hellmayr , 1919)
- Pseudocolaptes boissonneautii meridae ( Hartert & Goodson , 1917)
- Pseudocolaptes boissonneautii orientalis (Zimmer, 1935)
- Pseudocolaptes boissonneautii pallidus (Zimmer, 1935)
- Pseudocolaptes boissonneautii striaticeps (Hellmayr & Seilern , 1912)
The subspecies Pseudocolaptes boissonneautii oberholseri ( Cory , 1919) is usually considered a synonym for the nominate form .
The subspecies auritus is found in central Peru from the south of the La Libertad region to north of Puno . The subspecies boissonneautii is native to the western and central Andes of Colombia as well as in the east of the southern Cundinamarca . In the Andes south of Puno to central and southern Bolivia (eastern to western Santa Cruz ) one finds the ssp. carabayae before. In the Piura region and in the southwest of Cajamarca , the ssp. intermedianus . The subspecies medianus occurs south of the Marañón River from southern Cajamarca to the southern part of the San Martín region . The home of the ssp. meridae is in the Sierra de Perijá , in the Andes of north-west Venezuela (near Trujillo , Mérida and in the state of Táchira ). On the Colombian side, they can be found in the south of the Boyacá province . Oberholseri is probably a synonym for orientalis and occurs on the eastern and western slopes of the Ecuadorian Andes. Pallidus can be seen in northwestern Peru. Finally, one finds the ssp. striaticeps on the coasts of northern Venezuela. It is present there from the state of Yaracuy via Carabobo to Miranda .
Naming
The Andes' ear was originally described under the name Anabates Boissonneautii . Frédéric de Lafresnaye dedicate the scientific name to Auguste Boissonneau . Lafresnaye wrote: nous la dédions à M. Boissonneau, comme faisant partie de la riche collection qu'il a reçu de Bogota et comme un hommage des amis de la science, de ce qu'avant d'en livrer les nombreuses espèces à des mains étrangères, il a voulu, dans l'intéret de cette science, faire connaître les espèces nouvelles par ses propres descriptions ou celles des auteurs auxquels ils les a communiquées obligeamment. (Analogous translation: We dedicate the kind to Mr Boissonneau, who received part of his rich collection, which he received from numerous foreign hands in Bogota (Santa Fé de Bogotá) as part of the homage to the friends of science. In the interest of science and in Awareness of the need to describe new species by suitable authors, he had kindly made the bellows available to us).
