Spotted Scrubwren

Medium-sized warbler with green upperparts, yellow underparts, a bright yellow eyering, and a gray crown bound by two black stripes. Extremely similar to several closely related species; luckily, range prevents much confusion throughout these species’ natural ranges. Primary confusion species is Whistler’s Warbler, from which it may be distinguished visually, albeit with significant difficulty. In Green-crowned, note weak break at rear of eye-ring (while the eyering of Whistler’s is thickest at the back end), longer and more slender bill, shorter tail, more solidly black crown stripes, and slightly brighter green upperparts. As with many physically similar species, using a combination of these field marks is preferable in identification. Active, frequently flitting about in the lower levels of forest, sometimes associating with foraging flocks. Breeds in both evergreen and deciduous broadleaved forest in hilly and montane areas; moves to lowland areas in the winter. Averages lower than Whistler’s Warbler in altitudinal breeding preference, and overlap is fairly minimal. Song is a strung-together series of ringing “witchy-witchy-witchy” or “tzewee-tzewee-tzewee” phrases, and unlike song of Whistler’s, includes jumbled trilling segments. Call is a short, succinct “wit wit!”.

A slender tern with a short bill. Breeding adults are dark-capped with an ashy-gray body, a strongly contrasting white cheek stripe and rump, and a reddish bill and legs. In flight, underwings and uppertail are mostly grayish. In non-breeding plumage resembles other non-breeding terns, but note structure. Restricted to a handful of subantarctic islands, where it forages in inshore waters; common on Kerguelen and uncommon on Crozet and Marion. In breeding plumage, the larger Antarctic Tern is paler gray than Kerguelen, with a larger bill and whitish (not grayish) uppertail and underwings. Arctic Terns (in non-breeding plumage) only overlap with Kerguelen Terns (in breeding plumage) in austral summer.

A common tanager of savannas, forest borders, woodlands, and gardens. Often seen in pairs or with other species at fruiting trees, but usually not with mixed-species flocks. Males have a black face, throat, breast, and belly that is flanked by buffy sides. The crown and back are also buff and the wings and tail are dark-green. Females are buffy below with greenish back and wings, a pale throat, and a faint mask. The northern subspecies has a black mask (lacking the black throat and belly) with a violet gray throat and buffy belly.
