Nordmann's Greenshank
Tringa guttifer
Rare and declining Asian shorebird. Similar to Common Greenshank, with a burlier, more bull-headed appearance, shorter legs, and thicker bill. Breeding adult mostly gray above, white below, with densely spotted breast and upper sides. Nonbreeding adult pearly gray above and snowy white below. Bicolored bill is olive-green at the base, darkening towards the tip. Call is distinctive, usually a single nasal note, instead of the mellow “tu-tu-tu!” of Common Greenshank. Breeds in coastal marsh and sparse wet forests; winters on mudflats, coastal wetlands, aquaculture ponds, and paddies.
Identification
The Nordmann's greenshank is a medium-sized sandpiper, at 29–32 cm (11–13 in) long, with a slightly upturned, bicoloured bill, and relatively short yellow legs. Breeding adults are boldly marked, with whitish spots and spangling on black upperside; heavily streaked head and upper neck; broad, blackish, crescentic spots on lower neck and breast; and darker lores.
Taxonomy
It is fairly aberrant and was formerly placed in the monotypic genus Pseudototanus. It is an endangered species, and was not available for molecular analyses in Pereira & Baker's study (2005) of the genus Tringa. It appears closest overall to the semipalmata-flavipes and the stagnatilis-totanus-glareola groups, though it also has some similarities to the greater yellowlegs and common greenshank.

Range and habitat
The Nordmann's greenshank breeds in eastern Russia along the south-western and northern coasts of the Sea of Okhotsk and on Sakhalin Island. Its non-breeding range is not fully understood, but significant numbers have been recorded in South Korea, mainland China, Hong Kong, and Taiwan on passage, and in Bangladesh, Thailand, Cambodia, Vietnam and Peninsular Malaysia in winter. It has also been recorded on passage or in winter in Japan, North Korea, India, Sri Lanka, Myanmar (which may prove to be an important part of its wintering range), Singapore, the Philippines and Indonesia. There are unconfirmed records from Nepal and Guam (to US). It probably has a population of 500–1,000 individuals. It has been recorded several times on 80-mile beach in Western Australia and most recently an individual was discovered on Cairns Esplanade in Queensland, Australia. It was known to have over-wintered there from December 2020 to May 2021. In mid-December 2021 what is thought to be the same individual bird, returned to Cairns Esplanade. It has now returned for four straight seasons, being regularly seen in 2022 and 2023.

Bamboo Warbler
Locustella alfredi
Mid-sized warbler with a long tail. Dark brown overall, with a white throat and pale eye-line. Found very locally in middle-elevation habitats with a dense ground cover, including bamboo, forest, marsh, and lush grassy areas. Rare species that is not often seen. Most likely to be detected and identified by its distinctive song: a ratcheting up-and-down “dee-ka dee-ka dee-ka…” series which can last for several seconds. Very similar to Evergreen-forest Warbler, and best distinguished by its different song.
Slaty-capped Flycatcher
Leptopogon superciliaris
Small flycatcher with gray cap, black ear patch, and buffy wingbars. Head pattern looks messy. Olive back and pale yellow belly. Most similar to Sepia-capped Flycatcher, but that species has a brown cap (not gray). Also very similar to bristle-tyrants of South America but note buffy wingbars and voice—a commonly heard, explosive “pseek!” sometimes with a sputtering trill at the end. Look for singles or pairs in forests and edges, usually not too high in the trees. Often follows mixed-species flocks.
Fasciated Tiger-Heron
Tigrisoma fasciatum
This medium-sized heron is often seen along fast-flowing rocky rivers and streams, usually at higher elevations than other tiger-herons. Almost always seen singly, standing on a rock in the middle or on the edge of a river. Adults are gray with fine black barring down the entire head, neck, and wings. Juveniles are buffy with uneven black barring. Juveniles essentially identical to juvenile Rufescent Tiger-Heron, but note different habitat.
