The Peru Wren ( Cinnycerthia peruana ) is a bird art from the family of wrens (Troglodytidae) that in Peru endemic is. The IUCN assesses the population as Least Concern . The species is monotypical .

features

The Peruvian Wren reaches a body length of about 15.5 to 16.0 centimeters with a weight of about 19.6 grams. The top is magnificent chestnut brown, the neck and back a little less reddish than the top of the head and the rump . Many adult birds have varying degrees of white on the face, usually around the eye and the front of the skull. Occasionally the whiteness can be expanded further, which may have an impact on the social status in the group. The wings of the hand , the wings of the arm and the upper wing coverts are strongly chestnut colored and marked with thin black stripes. The control feathers are strong maroon with a fine black grid pattern. The chin and throat are orange-brown, the chest and flanks a little more dull and darker. The eyes are chestnut colored, the beak dark brown, yellow when opened. The legs are black. Both sexes are similar. Young animals are similar to adult birds, but never have white feathers in the facial area.

Behavior and nutrition

The Peruvian wren looks for food in the strata close to the ground and rummages through vegetation and rubbish. He is often out and about in groups, mostly from the extended family circle, which consists of couples, adolescents and young birds.

Vocalizations

The song of the Peruzaun king usually consists of a duet of both sexes. It contains an impressive series of strong trillers with clear whistles. Some of the song passages are reminiscent of the nightingale . The sounds are described as harsh, chattering ch-ddd tones that the group members often utter together. As with conspecific conspecifics, the singing is often given in the choir and consists of variable, musically sounding hums, whistles and tingling tones. Warning calls often sound in chorus and consist of quick, dry chatter.

Reproduction

Little is known about the breeding biology of the Peruvian Wren. A newly hatched chick and another nest with an egg were discovered in the Huánuco region in September. In August, fledgling nestlings and young animals were observed in February, June and November, which indicates a longer breeding season. The Huánuco nest was bag-shaped, about 20 centimeters wide, about 30 centimeters long and about 15 centimeters deep. The bag measured 10 centimeters by 10 centimeters by 15 centimeters, had a continuous entrance tunnel and was made of small roots woven into green moss and dry bamboo leaves at the top. The entrance area was surrounded by green moss. This was attached to curved bamboo stalks. The eggs are light creamy white with sparse red speckles.

distribution and habitat

The Peruvian wren prefers wet mountain forests, secondary vegetation and forest edges at altitudes of 1500 to 3300 meters. It occurs in the Andes of Peru from the Amazon region to the Ayacucho region.

migration

It is believed that the Peruvian wren is a resident bird .

Etymology and history of research

The first description of the Peruvian king was in 1873 by Jean Louis Cabanis under the scientific name Presbys peruanus . The type specimen was collected by Konstanty Roman Jelski near Maraynioc in the Jauja province . In 1846, René Primevère Lesson introduced the new generic name Cinnycerthia . This name is made up of "cinnuris κιννυρις " for "a small bird according to Hesychios of Alexandria ", a name that Georges Cuvier used in 1817 for a genus of nectar birds , and "certhios κερθιος " for "a small tree dweller who, according to Aristotle, eats insects" together. The type epithet »peruana« refers to the country Peru.
