ヒメアリサザイ Myrmotherula brachyura

Tiny, very short-tailed antwren of rainforest midstory and lower canopy. Males are yellow with white head and wing bars, and extensive black streaking on the head and back; females are similar to males, but have a red-orange wash on the head and more extensive streaking in the breast. Most common in young rainforest and around forest edges, where often found with mixed species flocks. Commonly detected by its song, an accelerating series of musical notes that rises and drops in pitch at the end.
