キイロシラギクタイランチョウ Elaenia pallatangae

Confusing flycatcher of montane forest. It has olive-gray upperparts, pale yellow underparts, white wingbars, and a small crest that is usually held flat. When crest is raised, it may show some white. Very similar to White-crested Elaenia, but usually brighter yellow on the belly and may show a more conspicuous eyering. Birds in worn plumage may not be identifiable with certainty. Its most common vocalizations, which include clear whistles and burry calls, are similar to those of other elaenias.
