Squacco Heron
Ardeola ralloides
Small stout heron; favors freshwater marshes, lakes, and ponds with reeds and other surrounding vegetation. Tends to hunt rather sluggishly, hunched quietly at the edge of the water. At rest, appears buffy brown overall, but in flight transforms to mostly white when white wings and tail are revealed. Breeding adult has a rich buffy neck; nonbreeding and immature have a streaked neck.

行为
The squacco heron is a migrant, wintering in Africa. It is rare north of its breeding range. The species has been recorded in Fernando de Noronha islands, and more rarely in mainland South America, as a vagrant.<p>This is a stocky species with a short neck, short thick bill and buff-brown back. In summer, adults have long neck feathers. Its appearance is transformed in flight, when it looks very white due to the colour of the wings.<p>The squacco heron's breeding habitat is marshy wetlands in warm countries. The birds nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Three to four eggs are laid. They feed on fish, frogs and insects.

Lesser Roadrunner
Geococcyx velox
Slightly smaller version of the familiar cartoon Greater Roadrunner, but usually the two species do not occur in the same places. Favors dry brushy woodland and overgrown weedy fields in tropical lowlands and foothills. Can be very elusive, but at other times runs out in the road or sits quietly sunning itself on a fence post or bush top in the early morning. Note that the center of the throat and breast are plain rich buffy, without the dense dark streaking of Greater Roadrunner.
Natal Spurfowl
Pternistis natalensis
A medium-size brownish francolin with distinctive yellow nostrils and a bright orange-red bill and legs. The back is mottled brown, and the underpart feathers are edged brown and white, giving it a marbled scaled appearance. Juveniles are similar to adults, with duller legs and bill. It is common in savanna, preferring thicker understory. The call is a loud raucous “kak-kreek” that variably accelerates and decelerates. Red-billed Francolin differs from Natal Francolin by having barred (not scaled) underparts and a yellow eye-ring. Swainson’s Francolin differs from Natal Francolin by having red facial skin and dark blackish legs.
White-bibbed Babbler
Stachyris thoracica
Handsome and well-named large babbler with a snow-white “bib.” Also note blue facial skin and bright chestnut back. Crown is brownish on birds from western Java, and grayish on those from central and eastern Java. Despite large size and bright colors, can be quite skulky and difficult to see well. Hops and clambers about in dense bushes and vines in foothill forests, typically in mid-sized groups, giving dry churring rattles. Also gives a short, fluty-sounding whistle.
