The stripe-throated wren ( Cantorchilus Leucopogon ) is a bird art from the family of wrens (Troglodytidae) that in Panama , Colombia and Ecuador is widespread. The IUCN assesses the population as Least Concern .

features

The striped-throated wren reaches a body length of about 12.0 cm. It is relatively difficult to describe as it has scattered markings on the throat. The reins are gray-brown, the stripe above the eyes is grayish white, the ear covers are dotted black and grayish white. The skull and the top are dark brown, a little reddish at the rump . The wings of the hand and the wings are reddish brown with fine black stripes. The dull, reddish-brown control feathers are criss-crossed with tight, blackish bands. The chin and throat have pointed gray-white with blackish lines that extend under the ear covers. These are clearly distinguished from the reddish yellow-brown color of the upper breast. The rest of the underside is reddish yellow-brown which becomes darker and more intense on the belly in the rump area. The eyes are light brown or reddish brown, the upper beak black to dark gray, the lower beak light gray with a blackish tip and the legs gray-black or gray-brown. Both sexes are similar. Young animals have less clearly defined strokes and the eyes are brown without the reddish tint.

Behavior and nutrition

Little data is available on the diet of the striped-throated wren. Some specimens' stomachs contained insects. Usually it is in pairs and looks for its food three to ten meters above the ground in dense vegetation. He regularly joins mixed groups from other species.

Vocalizations

The singing of the striped-throated wren consists of unmelodic two to three tones that sound like chi-chi-chi . There are no data on the otherwise common antiphonic duo of the sexes of this genre. The alarm call is somewhat similar to the singing elements.

Reproduction

In March, the striped-throated wren was seen building a nest in Panama. In north-western Colombia, birds were in breeding mood in April. The nest is a messy ball with a side entrance, which it usually places near a small branch without paying much attention to its concealment.

distribution and habitat

The striped-throated wren prefers the edges of secondary forest and Várzea . It moves at altitudes from sea level to 900 meters.

migration

It is believed that the striped-throated wren is a resident bird .

Subspecies

So far, two subspecies are known:

  • Cantorchilus leucopogon grisescens ( Griscom , 1932) occurs in northeastern Panama and northern Colombia. The subspecies looks much grayer and lighter on the top and bottom.
  • Cantorchilus leucopogon leucopogon ( Salvadori & Festa , 1899) is widespread in southeastern Panama, western Colombia, and northwestern Ecuador.

Etymology and history of research

The first description of the stripe-throated wren was made in 1899 by Tommaso Salvadori and Enrico Festa under the scientific name Thryophilus Leucopogon . The type specimen was collected by Enrico Festa in the forests around the Río Peripa in the province of Pichincha. In 2006, Nigel Ian Mann , Frederick Keith Barker , Jefferson Alden Graves , Kimberly Anne Dingess-Mann and Peter James Bramwell Slater introduced the genus Cantorchilus, which is new to science . This name is derived from "cantus" for "song" and "orkhilos ορχιλος " for "wren". The species name "leucopogon" is a Greek word formed from "leukos λευκος " for "white" and "pōgōn, pōgōnos πωγων, πωγωνος " for "beard". »Grisescens, griscescentis« stands for »greyish« from »griseum« from »gray«.
