Graumantel-Zaunkönig Odontorchilus branickii

A small, warbler-like wren of Andean cloud forest. Plumage is gray and white with a barred tail and vent, brownish crown, and faint streaking on the head. When seen from below in poor lighting conditions, the barred tail is usually the best feature to look for. Stays high in the canopy and is almost always encountered with mixed-species flocks. Vocalizations are very high-pitched and include gravelly trills and siren-like whistles.
