Papuan Scrubwren

This red-eyed masked-weaver has a plain olive-green back and pink-brown legs. The breeding male has a black face mask, with the black band on the forehead above the bill varying from broad in the south to narrow farther north. Female and juvenile are dull and inseparable from other masked-weavers. Pairs and colonies are localized residents of reedbeds, wetlands and adjacent woodland, in a narrow global range between northeastern Zambia and southeastern DRC. The breeding males of Katanga and Southern masked-weavers are very similar, but the former are smaller, have some saffron around the masks, and have darker green backs and rumps; breeding male Tanganyika and Lake Lufira Masked-Weavers have more burnt-orange around the face and underparts, and ranges do not overlap.

Widespread and fairly common; readily seen from shore and ferries in Tierra del Fuego. Giant-Petrels are known as vultures of the Southern Ocean and can scavenge with gulls at sewage outflows or with albatrosses at fishing boats; often follows ships. Very large (size of smaller albatross) with a very big pale bill that always has a diagnostic pale greenish tip. Plumage varies; most birds are dark overall or with whitish head, rarely whitish head and underparts; scarce white morph is snow-white overall with scattered black feathers.

This attractive warbler is nearly endemic to the Bolivian Andes, barely reaching over the border into Peru. Note the ornate head pattern and olive (not yellow) plumage. Most similar to Riverbank Warbler and the white bellied form of Golden-crowned Warbler, but has a dark loop below the eye and is found at higher elevations. Usually seen in pairs at lower to middle levels of cloud forest. Song is a rising series of piping notes followed by a chatter. Formerly considered a subspecies group of Three-striped Warbler.
