( Swainson , 1838)

The cheeks Streif Wren ( Pheugopedius genibarbis ) is a bird art from the family of wrens (Troglodytidae), in Brazil , Peru and Bolivia is widespread. The IUCN assesses the population as Least Concern .

features

The cheek-striped wren reaches a body length of about 15.5 cm with a weight of about 16.2 to 22.8 g. He has gray-brown reins and a black eye stripe, which clearly stands out from the white eye ring and the white over eye stripe . The ear covers are gray-black with conspicuous white lines. The top of the head and neck are olive-gray-brown, the back, the rump and the wing covers are light chestnut-colored. The wings of the hand and the wings of the arm are matt blackish brown on the hidden inner flags, and chestnut-colored on the exposed outer flags. The matt brown control feathers are crisscrossed by eight to ten blackish bands. The black line of the cheek also stands out from the white line of the beard. The throat and upper breast are white, the lower breast yellow-brown, the flanks and belly deep brown. This turns into a reddish brown at the under tail coverts. The eyes are reddish brown, the beak often black with slight variations. The legs are gray. Both sexes are similar. Young animals have a brown skull than adult birds. The back is more matte with less of a chestnut color and the markings on the face are more indistinct. This is especially true for the cheek stroke. The bandages on the tail are more blurred.

Behavior and nutrition

There are no reliable data on the diet of the cheek-streaking wren. Presumably feeds exclusively on invertebrates. He mostly looks for his food in the relatively low vegetation and often in pairs.

Vocalizations

The chant of the cheek-streaked wren is often given antiphonically by couples. It consists of a series of quick, exuberant phrases that are repeated regularly. The phrases are often followed by quick cho cho cho tones. The gurging quality of the songs of the bearded wren ( Pheugopedius mystacalis ) is missing , so that the songs are more similar to those of the corayazaun king ( Pheugopedius coraya ). Among his sounds is a tearful tchiyr tone, which he also sprinkles into his songs.

Reproduction

In the National Park Manú four nests of the cheek lining Wren were discovered with eggs from September to October. The nest had a dome-shaped and massive ball-like structure with a side entrance. A clutch consisted of two eggs. The eggs are white with varying numbers of reddish brown spots on the surface. An egg is approximately 20.0 × 14.8 mm in size. Only one parent, presumably the female, incubated the eggs. One newly hatched chick was completely naked and weighed 4.25 g.

distribution and habitat

The cheek-streaked wren prefers forest edges, including those on river banks, especially those with dense bamboo thickets of the genus Bambusa . Here it moves at altitudes from sea level to medium altitudes. In Bolivia it can be found up to 1500 meters.

migration

It is believed that the cheek-streaked wren is a resident bird .

Subspecies

There are four known subspecies.

  • Pheugopedius genibarbis juruanus ( von Ihering, H , 1905) occurs in eastern Peru, western Brazil and northwest Bolivia. The subspecies is slightly larger, has a larger beak, and is paler on the underside than the nominate form .
  • Pheugopedius genibarbis genibarbis ( Swainson , 1838) is common in central and eastern Brazil.
  • Pheugopedius genibarbis intercedens ( Hellmayr , 1908) occurs in the southwest and central southern Brazil. The subspecies has a slimmer beak, the top of the head is less soot-colored and there is no gray tint on the front neck.
  • Pheugopedius genibarbis bolivianus Todd , 1913 is common in the north and east of Bolivia. The subspecies is similar to P. g. intercedens , however, has a deeper ocher-colored underside. The sides of the neck are darker gray and the front neck is tinted ash gray.

Etymology and history of research

The first description of the cheek lining Wren was made in 1838 by William Swainson under the scientific name Thryothorus genibarbis . The type specimen came from Brazil. As early as 1851, Jean Louis Cabanis introduced the genus Pheugopedius, which was new to science . This name is derived from "pheugō φευγω " for "avoid, flee" and "pedion, pedon πεδιον, πεδον " for "open land, ground". The species name »genibarbis« is a Latin word formation from »gena« for »cheek, cheek« and »barba« for »beard«. »Juruanus« refers to the Rio Juruá , »bolivianus« to the country of Bolivia. "Intercedens" is the Latin word for "between" from "intercedere" for "to put in between, to insert".
