Andean Lapwing
Vanellus resplendens
Large, boldly patterned shorebird of high Andean bogs, wetlands, and lakeshores; also ranges into grassy pastures in the northern part of its range. Usually in pairs or loose flocks, feeding with typical stop-start action of plovers. Little or no range overlap with Southern Lapwing of lowlands and foothills. Note dove-gray head and breast (no crest) and pink bill and legs (duller on immature). In flight shows bold black-and-white pattern on wings and tail. Often noisy, especially when flushed.

分布与栖息地
The Andean lapwing is found in the Andes from southwestern Colombia south through Ecuador, Peru, and Bolivia into northern Chile and northwestern Argentina. It inhabits a variety of open landscapes including páramo and puna, shore meadows, and open parts of marshes. It is usually found near lakes or rivers but shuns saline waters. In general it ranges between 2,700 and 4,600 m (8,900 and 15,100 ft) of elevation but is found as high as 5,000 m (16,000 ft) in Chile and as low as 1,500 m (4,900 ft) in the southern parts of its range. It occasionally reaches the coast during the austral winter.

行为
The Andean lapwing is essentially resident in most of its range but moves to lower elevations during the austral winter.<p>Nothing is known about the Andean lapwing's foraging techniques or its diet.<p>The Andean lapwing's breeding season is mostly between October and December though occasionally it may extend to February. One nest was a depression in the ground lined with plant material including lichens. The clutch size is three or four. The incubation period and time to fledging are not known.<p>Like most lapwings, the Andean is noisy. "[U]sually heard are a sharp 'wik' in alarm, a harsh 'criee-criee-cri' call, a staccato 'cwi-cwi-cwi...' or more mellow and melodic 'dididi---celeec-celeec-celeec-ce...'." It also makes "a soft querulous 'cow' note...or a low, tremulous 'kwiwiwiwirrr'."

Green-tailed Goldenthroat
Polytmus theresiae
Medium-sized hummingbird of semi-open areas. Note entirely green plumage (including tail) and plain face with white spot behind eye. May be found in coastal savannas, savanna enclaves at lower elevations in the tepui region, and patches of dry scrub on rock formations in rainforest. Perches on low shrubs, often near temporary pools, preening and chasing other hummingbirds. Similar to Glittering-throated Emerald but lacks any white below and shows less contrast between face and throat. Frequently produced song is an excited, accelerating series of notes.
Baliem Whistler
Pachycephala balim
A medium-sized bird of montane forest and secondary habitat in the Baliem Valley. Typical male “golden” whistler, with yellow belly, black head and breast band, and a white throat. Female has a brown head and breast band with a scaled throat. Co-occurs with the similar Sclater’s Whistler, but Baliem male has a broad yellow band around the back of the neck, and female has a scaled rather than plain white throat. A jumbled, whistled song containing some notes with an explosive quality.
