The Panama Schopf ear ( Pseudocolaptes lawrencii ), sometimes Fahl cheek Astspäher called, is a species of bird from the family of Ovenbirds (Furnariidae). The species has a range that covers about 5,700 square kilometers in the Central American countries Costa Rica and Panama and the South American country Colombia . The IUCN assesses the population as not at risk ( least concern ).

features

The panama head ear reaches a body length of about 20 centimeters and weighs up to 48 grams. Most of the top is brown. The crown to the nape is dark with yellow-brown streaks. 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 yellowish brown to white. The upper part of the chest is also yellowish brown to white, but is streaked with brown speckles. The rest of the lower part is reddish yellow. On the side this turns red 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

The bird is found mainly in wet and mossy forest. You can see him at heights between 800 and 2000 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.

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. For his nest he likes to use abandoned woodpecker holes at heights between 5 and 10 meters.

Subspecies

So far, two subspecies are known within the species.

  • Pseudocolaptes lawrencii johnsoni ( Lonnberg & Rendahl , 1922)
  • Pseudocolaptes lawrencii lawrencii (Ridgway, 1878)

However, there are contrary opinions in the literature on the subspecies johnsoni . Some authors see it as a species of its own . The authors justify it with the spatial distance to the subspecies lawrencii and clear differences in plumage. This opinion follows u. a. the International Ornithological Committee ( IOC ). The Museo Ecuatoriano de Ciencias Naturales ( MECN ) even rates the species as endangered. The World Institute for Conservation Environment ( WICE ) also accepts the species. The South American Check-list Committee ( SACC ) has so far refused to recognize this subspecies as a separate species. Further knowledge is required here.

Another subspecies, Pseudocolaptes lawrencii panamensis ( Griscom , 1924) from western Panama, is considered an invalid taxon .

Etymology and history of research

Robert Ridgway received the type specimen from Adolphe Boucard (1839-1905), who had already described it in the Proceedings of the Zoological Society of London , but could not find any significant difference to the Andean crested ear ( Pseudocolaptes boissonneautii ).

The »pseudocolaptes« of the genus is derived from the Greek word »pseudo« for »false, fake, feigned« and »colaptes« for »woodpecker«. The specific epithet lawrencii honors the American businessman, collector and ornithologist George Newbold Lawrence (1806–1895).
