Ochre-bellied Boobook

Very similar to Reed Bunting, but smaller and more slender; also note finer bill, colder pale buffy-brown (instead of rufous) wing coverts, and less extensive streaking on the underparts. Breeding male has a black hood and bright white “moustache” stripe. Female and non-breeding birds are pale sandy brown with a pale but noticeable white “moustache.” Breeds in thickets and vegetation clusters in tundra and winters in reedbeds and tall grassy or brushy areas near water, where often associated with mixed-species flocks. Song is a series of wet buzzy “tsli” notes. “Chlip” calls distinctly sparrow-like.

Small flycatcher, extremely similar to several other species. Prefers clearings and boggy areas, often with patches of alders. Grayish-olive above and pale below with thin white eyering. Wings dark with bold white wingbars. Nearly identical to Willow Flycatcher; once considered the same species. Also compare with Least Flycatcher, which is very similar but has slightly shorter wingtips and a bolder eyering. Best identified by voice: song is a rolling, rough "freeBEER;" call is a clear "pip." Silent birds, especially in migration, often best left unidentified.

A wedge-billed Galápagos finch found only on Genovesa Island. Formerly considered a subspecies of Sharp-beaked Ground-Finch, and likewise has a sharp, thin bill with nearly straight edges. Bill is black on breeding male and dull orange on female and nonbreeding male. The only other slender-billed finch on Genovesa is the very different Gray Warbler-Finch, which has a thinner bill, tan (not sooty-black) adult male plumage, and paler and less heavily streaked female plumage. Common and easy to see in arid scrub near the coast.
