Long-billed and slender-appearing, the Yellow-throated Warbler commonly forages by moving methodically along branches. All plumages are similar and identification is straightforward. Upperparts are blue-gray, wings blue-gray with two white wingbars. Throat and upper breast are bright yellow, separated from the upperparts by a black border. The rest of the underparts are white with black streaking on the breast sides and flanks. The head has a long white eyebrow, a black eyeline and ear patch, and a white crescent below the eye. A large white spot on the side of the neck is a key field mark.
