The Méridazaunkönig ( Cistothorus meridae ) is a bird art from the family of wrens (Troglodytidae), which in Venezuela endemic is. The IUCN assesses the population as Least Concern . The species is considered to be monotypical .
features
The meridazaunig reaches a body length of about 10.0 cm. The white stripe above the eye becomes wider behind the eye. The reins and the ear covers are mottled brown, the top of the head and neck are medium brown with dark brown stripes. The shoulders and front back are blackish brown with white stripes. The rump and the upper tail coverts have matt black and warm brown stripes. The upper wing-coverts are light yellow-brown to brown with a striking dark-brown stripe pattern. The outer flags of the hand and arm wings are blackish brown and striped yellowish brown. The control feathers are medium brown with sharp black bands. The chin and throat are white, the chest yellow-brown, the flanks a deep yellow-brown with scattered dark stripes. The legs are yellow-brown with matt dark-brown stripes. The eyes are brown, the upper beak brown, the lower beak light pink. The legs are pink-gray. Both sexes are similar.
Vocalizations
The singing of the male meridazaun consists of twenty to twenty-five different songs. The repertoire varies from individual to individual as well as geographically. A song usually consists of two or three phrases, some of them poor whistles, others raspy or lively tones. A song is repeated several times before switching to another. The female makes dry trills or simple tones accompanied by the male. Tirades of rant sound like low whirring noises.
Reproduction
Little research has been done into its breeding biology. The duet in the vocals suggests a monogamous wren rather than a polygamous kind. Some sleeping nests were discovered in May and June. These have a side entrance, the outer shell consists of blades of grass. Inside he lays it out with the fine hair of the Espeletia leaves. One was discovered 50 cm above the ground on an Espeletia plant, the other in tufts of sedge.
Behavior and nutrition
The meridian wren feed on arthropods . He looks for his food in the lower strata of the vegetation.
distribution and habitat
The Méridazain king prefers moist páramo , typically with plants of the genus Espeletia and bushes. It moves at altitudes between 3000 and 4100 meters in the Andes of Venezuela from the south of the state of Trujillo on the Teta de Niquitao and south to the northeast of Táchira .
migration
There is some evidence that the meridaz wren moves on locally, presumably mostly only at high altitudes. So he seems to give up some areas in the rainy season.
Etymology and history of research
The first description of the Merida Wren was in 1907 by Carl Eduard Hellmayr under the scientific name Cistothorus platensis meridae . The type specimen was collected by Salomón Briceño Gabaldón in El Loro in the state of Mérida . As early as 1850, Jean Louis Cabanis introduced the genus Cistothorus, which was new to science, for the sedge wren ( Cistothorus stellaris ( Naumann, JF , 1823)). This name is derived from "cistos κιστος " for "bush" and "thouros θουρος " for "jump, run along". The species name »meridae« refers to the state of Mérida.
