The wren singer ( Zeledonia coronata ), formerly known as celedonia , is a small songbird and the only member of the genus Zeledonia . Robert Ridgway named the species after the Costa Rican ornithologist José Castulo Zeledón . The bird is placed in its own family Zeledoniidae and a relationship to the wrens (Troglodytidae) or the thrushes (Turdidae) was assumed, which is also reflected in the common English name wren-thrush . The species is common in Costa Rica and Panama . The IUCN lists them as “not at risk” (least concern).

features

Wren singer in Costa Rica

The wren singer reaches a body length of 12 centimeters. The wing length is 6 to 6.6 centimeters in the male, about 5.95 to 6.5 centimeters in the female. Adults and young birds from the first year on have an orange-reddish-brown crown, black side stripes, a weakly indicated dark eye line and a pale eye ring. The rest of the head plumage and the underside plumage is dark slate gray, with dark olive flanks and under tail coverts. The neck and top plumage is also dark olive. The wings and tail are dark brown with dark olive feather edges, the legs are dark brownish flesh-colored and the beak is blackish.

Occurrence, nutrition and reproduction

The wren singer is a resident bird and only migrates to a limited extent within the altitude of the locations it inhabits. The distribution area extends along the Cordillera de Guanacaste mountain range in the north of Costa Rica to the south-east of western central Panama. The wren singer inhabits dense bamboo undergrowth in cool, damp mountain forests as well as the tropical vegetation form Páramo at altitudes of 1500 to 2500 meters.

It feeds mainly on insects and spiders , which it digs up in the thick undergrowth. He prefers to lay his nest, made of moss with a side entrance, well hidden on moss-covered areas. The breeding season takes place between April and June. A clutch usually consists of two brown-spotted white eggs. There are no studies on the incubation time. The offspring will fledge after 17 days at the latest.
