Troglodyte de Serna Thryophilus sernai

This medium-sized wren has a very limited range in the Cauca Valley in Colombia. It is warm rufous-brown above and white below with a white eyebrow and faintly striped cheeks. The tail and undertail coverts are barred. Sexes similar. Pairs are found in dry forests, where they forage among thickets and vine tangles in the understory. Like many wrens, can be difficult to see, but listen for its relatively low-pitched flutey song.
