Australasian Bittern
Botaurus poiciloptilus
Large, stocky, strongly patterned heron with broad neck and yellow-green legs. Upperparts dark brown, underparts streaked. Usually found in reed beds, where it can be difficult to observe; often forages at night. When disturbed, “freezes,” with head pointing upward (as if trying to blend in with the habitat). Compare young Rufous Night-Heron, which is much smaller, has shorter neck, and tends to roost in trees. Song a very deep, slowly repeated "boom."
Identification
The length is from 650 to 750 mm with adults being similar between the sexes while the male is significantly larger. The bird has a deep brown upper surface, mauled with buff on wing coverts; face and eyebrow buff, with dark brown stripe running from bill to erectile plumes at sides of neck. Under surface buff, striped with brown. The face skin is a dull green as are the legs and feet, it possesses a dark brown bill, yellow eyes, and the base of the lower mandible is green-yellow.
Taxonomy
German zoologist Johann Georg Wagler described the Australasian bittern in 1827. It is one of four similarly plumaged species in the genus Botaurus.

Fulvous Parrotbill
Suthora fulvifrons
Small, ornate parrotbill with a pale belly and a long gray eyebrow. Orange overall with dark wing panels and a variable amount of white on the face. Central Chinese birds have a white face patch, while southern Chinese and Himalayan birds are limited to a short and largely unnoticeable white stripe under the cheek. Moves in large flocks through bamboo stands in coniferous and mixed foothill and montane forests. Lacks the dark throat of Black-throated and Golden Parrotbills.

Spur-winged Lapwing
Vanellus spinosus
This medium-large plover is often locally abundant, noisy, and easy to identify. Its plumage is a striking combination of black, white, and brown. It is very vocal, producing a piercing and repeated “sik-sik-sik…” call. It is found around wetlands, but also away from water in cultivated areas and even suburbia and urban settings. It forages mainly for arthropods, but also small reptiles and amphibians. Lays its eggs on the ground, and is often very aggressive against invaders to its territory, be it a crow or a falcon. Also active at night.

Green-tailed Warbler
Microligea palustris
Secretive, found in montane thickets and scrub, typically in or near forests. Usually solitary and rarely found in mixed feeding flocks. Soft gray of body and head contrast sharply with olive-green back and wings. It is similar to White-winged Warbler, but is gray rather than white below, has red eyes, and lacks white on the tail and wings. Song is a series of loud, sharp “tsip” notes. Calls include loud squeaky notes and raspy scolds.
