キノドアメリカムシクイ Setophaga dominica

A slender, long-billed warbler with distinctive pattern. Look for yellow throat, black mask, and black streaks on sides. All plumages are very similar; females and immatures often show a light buffy wash on the sides. Forages like a nuthatch, often creeping along branches and hanging upside-down. Fairly common breeder in mature forests with large sycamores or pines. Winters from the southeastern U.S. to Central America and the Caribbean, often in palm trees. Listen for sweet descending song with sharper notes at the end.
