How to know it
- Olive-green upperparts, bright yellow underparts, and a dark gray hood extending to the chest. Blackish lores and distinct white crescents above and below the eye are key features.
- Similar to males but generally duller in coloration, with a paler gray hood and lacking the black lores.
- Mostly olive-brown above with whitish eye arcs. The hood is grayish or brownish and often broken up by a pale throat, making them even more drab than females.
- All plumages feature sharp white crescents (arcs) both above and below the eye, a crucial distinguishing mark.
