features

The Socorro wren reaches a body length of about 11.0 to 12.0 cm. The reins are yellow-brown, the eye-stripe light yellow-brown, the ear covers are speckled gray-yellow-brown. The skull is gray-brown with some darker feathers in the middle. The shoulders and the back are gray-brown with indistinct fine stripes. The rump is colored rather warm brown. The outer flags of the hand and arm wings are blackish-gray and gray-white stiffened. The gray-brown control feathers have grayish-black bands. The chin and throat are yellow-brown-white, a color that becomes even more intense on the chest and whitish on the belly. The flanks and rump are yellow-brown. The upper beak is dark brown, the lower beak lighter and the legs brown. Both sexes are similar. Juveniles resemble adult birds but have more conspicuous scales on the underside.

Behavior and nutrition

What the Socorro wren feeds on has not been researched. He prefers to look for his food in the lower strata and on the ground by turning leaves. He also climbs tree trunks, much like tree creepers do.

Vocalizations

The Socorro wren's singing usually begins with two or more gruff chuk tones, which are broken up into short, powerful, slightly scratchy warbles and often ends with powerful gurgles or clear suit, uit-uit tones. The female sings opposite to the male and contributes gruff chatter. The song is reminiscent of that of other wrens with the exception of the bush wren . Schimpf end Tschuk, Tschuk sounds and fast Chir Chir- Tones part of his repertoire.

Reproduction

The Socorro wren appears to be breeding at the beginning of the year, but no reliable data is available. There were families with fledglings in April. A nest was discovered in a knothole in a decaying tree. The construction was not described.

distribution and habitat

The Socorro wren prefers woodlands and bushy hills.

migration

The Socorro wren is considered a resident bird .

Etymology and history of research

The Socorro wren was first described in 1868 by Andrew Jackson Grayson under the scientific name Thryothorus sissonii . The type specimen was collected by Grayson on the island of Socorro. As early as 1809, Louis Pierre Vieillot introduced the genus Troglodytes, which was new to science . This name is derived from "trōglē, trōgō κτρωγλη, τρωγω " for "cave, gnaw" and "-dutēs, duō -δυτης, δυω " for "diving, immersing". The species name »sissonii« is dedicated to the US consul of Mazatlán Isaac Sisson (1828–1906).
