Bruce's Green-Pigeon

Medium-sized gull with a long, slender bill. Breeding adult has a clean white head and dark red bill, and frequently shows a strong rosy-pink flush to the underparts. Non-breeding adult similar, but may show slight smudge on the head. Immature has orange bill with small brown patches on the wings, most readily seen in flight. Compare with Black-headed Gull; note Slender-billed's longer bill, sloping forehead, and "snouty" profile. Breeds in colonies in inland and coastal wetlands, but restricted to coastal wetlands when not breeding. Away from main range, found singly or in pairs, at times in association with much commoner Black-headed Gull.

Large, plain, long-tailed cisticola with a rufous cap, gray-brown back, and pale whitish underparts. Found in open habitats with grass and small trees, often in rugged and mountainous areas. The song is a musical series of high-pitched trills and whistles. As with all cisticolas, habitat and voice are important cues in identification.

Fairly common locally in the Andes, often near bogs or other areas with water. Often in flocks, feeding on the ground or in low bushes. Plumage is distinctive, with blackish head and breast, dark back, and bright yellow underparts. Namesake yellow rump usually concealed at rest. Sexes similar, but male averages blacker above. Juvenile looks very different, with greenish head and upperparts, and an orangish bill. No similar species in range, but sometimes associates with Thick-billed and Black Siskins.
