Black-rumped Buttonquail
Turnix nanus
Small, brownish quail-like bird. Generally rare and elusive species that is unlikely to be seen by those not expressly looking for it. The face is orange, and in flight, a large black rump patch is obvious. Found very locally in moist grassland. Gives a long series of low “hoo” notes. Very similar to Small Buttonquail, but separated by orange face and black rump. Also similar to female quail, but differs in less explosive flight and black rump.
识别特征
This species has a brown back, rufous chest, and pale belly, brown irises and a black rump. As usual for buttonquails but not for most birds, the female is larger and brighter than the male. The birds are shy and difficult to flush.
分类信息
The Black-rumped buttonquail, scientific name Turnix nanus, belongs to the family Turnicidae, which includes buttonquails or hemipodes. The family is part of the order Charadriiformes, which also contains shorebirds, gulls, and auks. The Turnicidae family consists of 16 species of buttonquails found in Asia, Africa, and Australia.The Black-rumped buttonquail was first described by the British naturalist Thomas Horsfield in 1821. The species was initially classified as Tetrao nanus but later placed in the genus Turnix. The Black-rumped buttonquail is one of the smallest buttonquail species, measuring only about 15 cm (6 in) in length and weighing around 30 g (1 oz).There are no recognized subspecies of the Black-rumped buttonquail, but the species does exhibit some genetic diversity across its range. In recent years, genetic studies have helped to clarify the evolutionary relationships within the Turnicidae family and have led to the recognition of several new species.Overall, the Black-rumped buttonquail has a relatively well-understood taxonomy, but further research is needed to fully understand the genetic diversity and relationships within the Turnicidae family.

White-cheeked Cotinga
Zaratornis stresemanni
Rare cotinga found only in high-elevation woodland in the western Andes of Peru. It is heavily streaked with brown and buff and has a white face and black cap. Feeds mainly on mistletoe berries; may rest on exposed branch for long periods of time when not feeding. Typical song is a series of sharp rasps that speeds up and then slows down again.
Musk Duck
Biziura lobata
Large and chunky stiff-tailed diving duck with a heavy triangular bill. Floats very low in the water. Both sexes are dark grayish, but male has an obvious lobe of skin dangling from its chin. Usually observed on the water, regularly diving while feeding. Bill is much shorter and heavier than Blue-billed Duck.
Indian Scops-Owl
Otus bakkamoena
Medium-sized scops-owl with prominent ear tufts and dark eyes. Coloration variable, ranging from gray to brown, but dark eyes, thin black border around the facial disc, and lightly streaked underparts remain constant. Gives bouncy amphibian-like barks at changing intervals. Inhabits forests, forest edges, parks, and gardens from lowlands up into foothill and montane regions.
