Salvadori's Antwren
Myrmotherula minor
Rare short-tailed antwren found in the understory of humid forests where it is very active and is normally associated with mixed-species flocks. Males are gray with a black throat and dark wing coverts with white spots. Resembles White-flanked Antwren, but without the white on the flanks. Females have a grayish head, a buffy body, and lack the male’s wing spots. The song is a high-pitched “veet…veet.”

Their throat and the center of the upper breast are black; their crissum has blackish bars. Adult females have a gray head and olive-brown upperparts. Their tail and wings are dull rufous-brown; the tail feathers have russet edges and the wing coverts thin buff edges.

分类信息
Salvadori's antwren is monotypic. It, the Rio Suno antwren (M. sunensis), and the slaty antwren (M. schisticolor) have similar morphology, behavior, and voices and may form a monophyletic group.<p>The species' English name honors Italian zoologist and ornithologist Tommaso Salvadori, who first described it.

分布与栖息地
Salvadori's antwren is a bird of the Atlantic Forest. It found very spottily and locally in coastal eastern Brazil between Bahia and extreme northeastern Santa Catarina. It inhabits the understorey to mid-storey of evergreen forest and adjacent mature secondary forest in the lowlands and foothills. It favors the forest interior and usually occurs near running water. In elevation it mostly occurs below 500 m (1,600 ft) but is found as high as 900 m (3,000 ft).

行为
Salvadori's antwren is believed to be a year-round resident throughout its range.<p>The diet of Salvadori's antwren's diet is not known in detail but is probably mostly mostly insects and spiders. It forages singly, in pairs, or in family groups, and usually as part of a mixed-species feeding flock. It typically forages around the crown and perimeter of trees with medium-size to large leaves. It feeds mostly between about 4 and 8 m (10 and 30 ft) above the ground but will go as low as 1 m (3 ft) and as high as 12 m (40 ft). It seeks prey mostly by gleaning live leaves, and also takes prey from clusters of dead leaves, moss, and hanging Usnea lichen.<p>The breeding season of Salvadori's antwren includes October but is otherwise undefined. Nothing else is known about its breeding biology.<p>The song of Salvadori's antwren is "short twittering, starting extr. high, completed by liquid 'tyweet-tweet-tueet' ". Its calls include "variable...short whistles, given singly", "sharp chips, often in short series", and the same chips in a longer, more widely spaced, series.

Fiery-breasted Bushshrike
Malaconotus cruentus
A massive arboreal bushshrike of lowland forests. Shaped like a typical bushshrike but oversized, with a giant bill. Throat and breast are orange-red, fading to yellow under the tail. Head is gray with two giant white spectacles around the eyes. The back, wings, and tail are yellow-green with dark spots at the tips of the secondary flight feathers and tail. Locally overlaps with Lagden’s Bushshrike and possibly with Green-breasted Bushshrike and Monteiro’s Bushshrike, but Fiery-breasted is unique in its combination of orange-red breast and bright white spectacles. Gives a series of short, ringing hoots, “kwhop, kwhop,” sometimes spaced out by several seconds.
Herald Petrel
Pterodroma heraldica
Medium-sized, lightly built petrel of offshore tropical waters across the Pacific; not seen from mainland. Plumage is highly variable (from white-bodied and dark-headed to wholly dark) and often very similar to larger and broader-winged Kermadec Petrel, which has a shorter and broader tail than Herald. Herald has white flashes on underside of wingtips, but lacks white shafts on upperside, which are diagnostic of Kermadec. Both species visit colonies in daytime, when pairs chase around high overhead.
Ijima's Leaf Warbler
Phylloscopus ijimae
An uncommon migrant songbird through Taiwan, rarely encountered anywhere away from breeding grounds on Izu and Tokara Islands, Japan. Olive above and whitish below; best distinguished from similar species by narrow bill with yellowish lower mandible, brownish-pink legs, and weak head pattern. Prefers mature coastal broadleaf forests but uses bamboo patches and conifers during migration as well. Smaller than Eastern Crowned Leaf Warbler, with thinner bill and no crown stripe. Song consists of a series of trills; calls, given often, include a descending “twee” or quiet “pee.”
