Rufous-tailed Babbler

Angry-looking bird with a long spiky tail and brown plumage contrasting with a black throat and a rusty shoulder patch. Occurs in arid, scrubby woodlands where normally forages on or close to the ground. The song is a repetition of a short, fast “quebéc.”

Tiny rail, the size of a sparrow and nearly impossible to see without tremendous effort. Slate gray overall with a piercing red eye, brown nape, and white spotting on wings. Beware confusion with downy young of other rail species, which are entirely black. Inhabits drier areas in fresh and saltwater marshes with cattail, sedge, and other tall grasses. Typically rare even in proper habitat. Incredibly difficult to locate even when vocalizing within mere feet of an observer; stealthily dashes around at the base of dense grass like a ninja. Easiest to detect by its distinctive song, most often heard at night: a churring "kick-ee-derr", two higher notes followed by a lower note.

A critically endangered Galápagos finch found only on the island of Floreana. Bill is moderately curved on both upper and lower edges, and slightly longer than it is deep. Male has a black hood, brownish-olive upperparts, and a pale belly. Female is tan with whitish underparts. Both sexes have faint streaking on the breast. Bill is black on breeding male and orange on female and non-breeding male. Large Tree-Finch has larger and more bulbous bill. Small Tree-Finch has slightly smaller bill and body. Identification is much easier when more than one species is present to allow direct comparison. Medium Tree-Finch inhabits forest mainly in the highlands but is occasionally seen closer to the coast, where it may be only a seasonal visitor.
