Northern Pied-Babbler

Colorful for an antwren, and therefore might be difficult to place into the correct family at first. Small. The distinctive rufous rump can be hard to see, so note black cap, gray head, olive back, yellow wingbars, and yellow belly. Bill is quite long and narrow. Female is similar to male but slightly duller. Typically found in pairs. Follows mixed-species flocks through the forest, usually fairly high in the canopy.

Massive kingfisher with a large scarlet bill. Head is olive-brown with dark green-blue upperparts and buff underparts. Wings and tail bluer, with rump even paler blue, obvious in flight. Juvenile has dusky edges to feathers of breast and hindneck. Vocal in breeding season, giving a loud, far-reaching “peu-peu-pow” whistle, while its regular contact call is a loud laughing “ka-ka-ka” repeated 6-10 times. Prefers large streams, rivers, and the edges of large water bodies with vegetated banks. 

Small but rather stocky and stout-billed petrel of subtropical eastern Pacific and Humboldt Current; not seen from mainland. One of several similar species, Masatierra is best identified by gray head and collar at sides of neck, rather stout bill, and plain grayish tail without a black tip. Much smaller than Juan Fernandez Petrel with quick wheeling flight unlike more easy and less hurried-looking flight of Juan. Also compare with Stejneger’s and Cook’s Petrels.
