Pardusco

This dove is accurately but misleadingly-named, for the male’s whole upper body is white, not just his throat; he also has a wine-red patch on the back and upperwing. Female is dirt-brown with darker back and wings. Inhabits the Northern Mariana Islands and Yap, in the Caroline Islands. Found in both pristine and degraded forest, often near habitated areas. Forages primarily on the ground on Yap and in trees and bushes on the Marianas. Coos are deep and sonorous.

A stone-colored terrestrial bird of stony hillsides, mountain ridges, and meadows above treeline. Adults speckled gray and white above, with dense rusty streaking on white underparts, red bill, and deep red legs. Usually forages in small groups, often in very exposed areas such as cliff sides and rocky ridges. Song, often given by multiple birds in a group simultaneously, is high-pitched and has a slippery, squeaky quality like wet shoes on tile; male song louder and ascending, female’s softer and descending.

Fairly distinctive for a pipit: blackish-brown above, including the wings, with bright golden feather edgings giving it a boldly streaked appearance. The chest and flanks are buff and lightly streaked. Look for the buffy-yellow eyebrow. Mostly encountered in well-preserved natural grasslands, favoring short grass areas that have regenerated after fires. Gives a series of sharp twittering notes ending with a slurred “eeeeeeeur.”
