Naretha Bluebonnet
Northiella narethae
Brown parrot with yellow belly, red undertail, and blue face, found in dry woodland habitats of the extreme southeastern part of Western Australia, on the western fringe of the Nullarbor Plain. In flight, the blue wings and red shoulders contrast with pale brown back; lacks the bright green back of other desert parrots. Identify from the very similar Greater Bluebonnet by a completely yellow belly and also by range.

分布与栖息地
The Naretha bluebonnet is reported to have been common in the arid Nullarbor region, and became rarer during the 20th century. The localised range of individuals is thought to make the species highly endemic to an area on the border of Western and South Australia.Narethas are located in what is termed the Myall woodlands - this is a woodland dominated by acacia species.The Naretha homelands extend over a large and isolated range. They are often observed more readily in areas where water has become an altered focal point - notably water troughs for stock.

Junin Grebe
Podiceps taczanowskii
Critically endangered grebe found only on Lake Junín in the high Andes of central Peru. Adults are gray and white with a ruby-red eye; young birds have a brownish tinge. Extremely similar to the far more common Silvery Grebe, but Junin Grebe is slightly larger with a longer bill, a skinnier neck, darker flanks, and a paler bill. These differences are more evident when both species are present, to allow for direct comparison. Not easily seen or identified from the lakeshore; a boat is usually needed for close-up views.
Peruvian Sheartail
Thaumastura cora
Tiny hummingbird of desert lowlands and foothills; found in gardens, agricultural areas with flowers, and native scrub. Adult male with long black-and-white tail “streamers” is basically unmistakable, but greatly outnumbered by females and immatures, which look much like several other small hummingbirds. On females and immatures note the relatively long tail with pale edging to the shorter central feathers and lack of rusty tones to the plumage overall.
Golden-backed Weaver
Ploceus jacksoni
Adult male is bright yellow with a glossy black head and rusty-orange underparts. Female is dullish yellow overall and can be difficult to distinguish from other female weavers. Look out for Weyns’s Weaver, which has a similar color pattern, but a black back in the male and pale eyes in both sexes. Inhabits wetland areas and builds an oval nest. Native to eastern Africa; established species in Singapore and the United Arab Emirates.
