Yellow-throated Bunting

Plain brownish warbler, without any striking features—in itself a field mark. Note hint of paler eyering, diffuse gray patch on side of neck, and relatively stubby bill for a warbler. Found in a wide variety of wooded and shrubby habitats, where it is often rather sluggish and easily overlooked. Pleasant, rich warbling song much like a Blackcap song, but tends to be more even-paced and less emphatic. Gives dry “chekchek” calls, often in series, similar to those of Blackcap.

Large gnateater with striking plumage. Note the bold white eyebrow. Males have a black head and underparts contrasting with chestnut wings and back; on females the black is replaced by gray. Occurs patchily in humid forest with dense understory, especially bamboo, where it forages on the ground and in the understory. The song is a short angry rattle.

Large, stocky gull of the North Pacific. Generally fairly pale and uniform-looking; at all ages, note wingtips and back are approximately the same color. Takes four years for immatures to progress from mostly brown to fully white and gray adult plumage; intermediate plumages are often mottled and messy. Most immatures look frosty grayish-brown with smooth patterning. Found in coastal areas, including beaches, mudflats, and even city parks. Identification is complicated by frequent hybridization with Western, Herring, and Glaucous Gulls in various parts of range. Pure birds can be difficult to find and identify with certainty, and many intermediate birds are best left unidentified.
