Noronha Vireo

Fairly small and typically plain greenbul. The pale bill and legs are unusual. Also note the pale whitish or orangish eye. Found in the thick undergrowth and mid-story of forest. Usually in small, vocal groups. The distinctive call is an accelerating series of nasal barking notes. Similar to several other greenbul species, but separated by the pale bill and legs. Further separated from Cabanis’s Greenbul by the lack of yellowish tones on the underparts.

Rather large, dark, stocky gull-like seabird with big white wing patches (seen in flight). In summer often seen flying over Patagonian steppe or associating with Kelp Gulls at beaches, dumps, river mouths, and lakes near the coast. Also found well offshore, where it chases other birds to steal their food. Usually seen as singles or small groups. Plumage variable, but always with some orange tones—sometimes bright and extensive, sometimes limited to underwing and base of tail. The only skua likely to be seen in Chile and southern Argentina.

Male is unmistakable, with a glowing silver supercilium, black hood, and fiery orange shoulder and collar. Female is more somber in plumage, brownish above, buffy below, with a trace of the male's pale brow. White-browed Bush-Robin is superficially similar, but darker gray above, with a more prominent supercilium. Inhabits montane regions, often in forest edge or open areas above the treeline.
