ホオスジカマドドリ Cranioleuca antisiensis

Handsome spinetail of Andean forest and scrub; ranges from southern Ecuador to central Peru. Plumage is grayish-brown with a white eyebrow and bright chestnut crown, wings, and tail. Birds in Ecuador and far northern Peru are slightly smaller and tend to be browner, with a bit less white on the throat. Typically found in pairs at any level, and often quite vocal. Typical song is a few sharp squeaks followed by a descending trill.
