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.

Gray Teal
Anas gracilis
Plain grayish mottled duck with a rounded crown. Note plain face lacking the bold stripes of Pacific Black Duck. White wing panels are distinctive in flight compared to purple/green of Pacific Black Duck. Told from female Chestnut Teal by the much paler neck/throat. One of the most common ducks in many waterways, forming enormous flocks numbering in the 1000s.
Southern Yellow White-eye
Zosterops anderssoni
A small, sharp-billed warbler-like bird that is saturated with yellow. Note the yellow underparts, olive-yellow back, and bold white spectacles around the eyes. There is some geographical variation, with montane populations generally darker with a broader eye-ring, and lower-elevation savanna populations paler with a narrower eye-ring. Found in forest, savanna, scrub, gardens, moist woodland, and plantations, usually in hyperactive flocks that can contain many individuals. Often joins mixed flocks with other small birds. Most common call is a high-pitched rising rattle. Song is a quiet, chatty sequence of “chew” notes. Similar to Pale White-eye, but usually separated by range; shows more yellow above the bill, is more richly-colored overall, and prefers moister habitats. Similar to Green White-eye, but slightly paler and usually separated by range. Also similar to Northern Yellow White-eye, though usually separated by range; identification in areas of overlap is poorly understood.
Rusty-winged Antwren
Herpsilochmus frater
A small antwren with a relatively long tail and bill. Widespread, occurs from eastern Panama to central Brazil. Bright plumage for an antwren: look for its yellow belly, rufous wings, bold white wingbars, and dark eyeline. Sexes are similar, but female has a rufous cap, which is black on male. Most often seen in pairs, foraging in the low to middle levels of lowland and foothill forest. Frequently follows mixed-species flocks. Listen for a short, harsh, rapid trill that accelerates into a growl.
