description

The Santander wren is about six inches long. It is generally reddish brown and white. The hood and coat are olive brown. The rest of the top is reddish brown and gives it a two-tone appearance. The face shows a protruding white eye stripe. The wings and tail are banded in black. The head flanks are dashed in black and white. The underside is white with light gray-brown flanks and sides. The under tail-coverts are banded in black. His singing consists of several deep, slow, soft, lively whistles preceded by high notes.

status

For a long time the Santander wren was only known from ten specimens that were collected between 1944 and 1948 near San Gil on the Rio Fonce south of Bucaramanga . It was not until 1989 that two more birds could be seen. The next sighting was again in 2000. The Nicoforo wren occurs only on the western slopes of the east in Santander . Here he lives in dense acacia shrubland in a semi-arid valley of the large intramontane drainage basin of the Rio Sagamosa at an altitude of 1095 m. To the north of San Gil, the hills are dominated by coffee and sugar cane plantations , which are avoided by this bird. The habitat of the Niceforo wren has been greatly changed by agriculture, the acacia bush is also endangered by overgrazing by goats and cattle.

Etymology and history of research

The first description of the Santander wren was in 1946 by Rodolphe Meyer de Schauensee under the scientific name Thryothorus nicefori . The type specimen was collected by Hermano Nicéforo María on November 19, 1945 near San Gil. In 1864, Spencer Fullerton Baird introduced the genus Thryophilus, which was new to science . This name is derived from "thryon θρυον " for "reed" and "philos, phileō φιλος, φιλεω " for "lover, lover, love". The species name is dedicated to the clergy, natural scientist and collector of the type specimen.
