Ruddy treerunner Margarornis rubiginosus

This small forest bird is bright rufous overall with an obvious white throat and eyebrow. Similar to various spinetails and foliage-gleaners, but it’s the only small rufous-brown bird in its range with such a prominent head pattern. Usually seen singly or in pairs, often following a mixed-species flock. Found in montane forests and edges from 1200m up to treeline. Hitches up mossy branches, probing around for invertebrates.
