ウスグロヤブハエトリ Sublegatus obscurior

A confusing flycatcher, fairly small and nondescript. Look for the short bill and round head, sometimes raised into a slight crest. Dull grayish-brown head shows only a hint of a paler line above eye. Chest is paler gray, which blends into the pale yellow belly. Wingbars are present but not bold. Larger and lankier than a beardless-tyrannulet; looks rather like a diminutive Myiarchus flycatcher. Very similar to Southern Scrub-Flycatcher, which may overlap during the Austral winter, but note the overall darker coloration of Amazonian.
