The teardrop-breasted branch scout or the Pacific crested ear ( Pseudocolaptes johnsoni ) is a species of bird from the family of the potter birds (Furnariidae). The range of the species includes the South American countries Colombia and Ecuador . The bird is classified as "not endangered" ( least concern ) by the IUCN . However, the IUCN follows the guidelines of BirdLife International , which considers P. johnsoni to be a subspecies of the Panama Cougar on the basis of an application by the South American Check-list Committee ( SACC ) . This contrasts with the opinion of the International Ornithological Committee , which regards Pseudocolaptes johnsoni in its list as a separate species.

features

The teardrop-breasted branch scout reaches a body length of about 20.5 centimeters. The top is mostly maroon. In contrast to the panama head ear, the back is also not adorned with strands. The rump and tail are reddish brown. The wings are mainly black and streaked with faint cinnamon-colored spots. The black head is adorned with a yellow-brown eye line similar to an eyebrow. The throat is exclusively yellowish brown and contains no white. The upper part of the breast is dark yellowish brown to white, but is traversed by white angles. In contrast to the panama ear, this does not look like scaled stripes. The rest of the underside is noticeably reddish yellow. This turns red on the side and is patterned with white stripes towards the chest. The black beak is yellow at the end and lower jaw. The legs are olive green.

Habitat and Distribution

The bird is found mainly in wet and mossy forests. He likes to move about in the treetops and mountain foothills of the lower subtropical forest. It can be seen at altitudes between 700 and 1700 meters. Here you can see him in epiphytic forests or in open terrain with scattered trees, where he searches the moss for beetles, cockroaches, spiders or salamanders. Overlaps of the habitat of the teardrop-breasted branch scout and the panama-eared ear are not known. The bird can only be found on the western slopes of the Andes of Ecuador and Colombia.

behavior

The bird likes to cling to trees and climb on them. The tail serves as a support. Often he climbs on the branches of the middle and higher canopy. Usually he is out in troops. He likes to use abandoned woodpecker holes for his nest.

Subspecies

No subspecies are known within the species. However, the taxon johnsoni is valued differently in the literature. Some authors see it as a separate species, Pseudocolaptes johnsoni . Others consider it to be a subspecies of the Panama shank ear ( Pseudocolaptes lawrencii ). The status as a separate species is justified with the spatial distance to the taxon lawrencii and clear differences in the plumage. The International Ornithological Committee ( IOC ) agrees with this opinion . The Museo Ecuatoriano de Ciencias Naturales ( MECN ) even rates the species as endangered. The World Institute for Conservation Environment ( WICE ) also accepts the status as a species. The South American Check-list Committee ( SACC ) has so far refused to recognize the taxon johnsoni as a separate species. Further taxonomic research is necessary here.

Etymology and history of research

Axel Ax: son Johnson (1876-1958)

Einar Lönnberg and Hialmar Rendahl described the teardrop-breast scout under the current name Pseudocolaptes johnsoni . The genus Pseudocolaptes was introduced in 1853 by Heinrich Gottlieb Ludwig Reichenbach for the Andes' ear ( Pseudocolaptes boissonneautii ). This name is made up of the Greek words »pseudos ψευδος « for »wrong, other« and »kolaptēs, kolaptō κολαπτης, κολαπτω « for »picker, peck, chop«. The specific epithet »johnsoni« is dedicated to the consul general Axel Ax: son Johnson .
