Grass-green Tanager
Chlorornis riefferii
Large, bulky tanager found in the upper subtropical and temperate zones of the Andes from Colombia to Bolivia. Striking and not likely to be mistaken: entirely bright green with red bill and legs and rufous face and undertail coverts. Fairly common in montane forests and edges, where singles or pairs often move slowly with mixed-species flocks. Forages at all levels. Listen for its distinctive nasal call notes.
分类信息
The grass-green tanager was formally described in 1840 by the French ornithologist Auguste Boissonneau from a specimen collected near Bogotá in Colombia. He coined the binomial name Tanagra riefferii. The species is now the only member of the genus Chlorornis that was introduced in 1850 by the German naturalist Ludwig Reichenbach. The genus name combines the Ancient Greek khlōros meaning "green" and ornis meaning "bird". The specific epithet was chosen to honour the collector Gabriel Rieffer. The grass-green tanager has a sister relationship to the genus Cnemathraupis containing the black-chested mountain tanager and the golden-backed mountain tanager.<p>Five subspecies are recognised:

Sapphire-bellied Hummingbird
Chrysuronia lilliae
Rare, endangered, and poorly known hummingbird restricted to mangroves and adjacent scrubby areas along the Colombian coast. Male has sapphire underparts extending from throat all the way to belly, and lacks the distinct hood typical of the more common Sapphire-throated Hummingbird. Female’s plumage is not known with certainty, but likely resembles female Sapphire-throated Hummingbird, which has white central underparts bordered by green flanks, and white tail tips.
Greater Bluebonnet
Northiella haematogaster
Brown parrot with yellow-and-red belly and deep blue face, typically found in dry inland habitats in eastern Australia. Multiple subspecies vary in the color of their wing patch, belly, and undertail. Usually seen in small groups, this species is often hard to approach and is easily flushed. In flight, the blue wings and red shoulders contrast with pale brown back. Distinguished from the similar but smaller Naretha Bluebonnet by presence of red on belly.
Slender-billed Gull
Chroicocephalus genei
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.
