オオアシオタテドリ Scytalopus macropus

Small, gray bird found in cloud forest along the east slope of the Andes in northern and central Peru. Adults are plain gray; young birds are marked with brown and buff. As with many other tapaculos, geographical range and voice are critical for identification. This species does not overlap with Unicolored Tapaculo, but confusion is possible with Blackish Tapaculo and Tschudi’s Tapaculo. Typical song is a steady and seemingly endless series of soft, frog-like calls, slower-paced than Blackish Tapaculo. Inhabits dense understory, especially near streams, and very hard to see.
