Azores Bullfinch
Pyrrhula murina
Restricted to São Miguel Island in the Azores; found in steep-sided valleys in laurel forests. Medium-large, plump finch with a strong, deep bill and short, rounded wings. Both sexes resembles a female Eurasian Bullfinch, with a black crown, face, and neck, but Azores are dark brown above and light brown below unlike the reddish-orange bellied male Eurasian Bullfinch. Tail and wings are largely black albeit with a white bar. The call is a soft melancholic “phew.”
识别特征
The Azores bullfinch has a length of 15–17 cm (5.9–6.7 in) and a weight of about 30 g (1.1 oz), with males being slightly larger than females. Relative to most other finches in its family it is plump, with shorter wings and a longer tail. The plumage pattern is similar to that of the Eurasian bullfinch, though colouration is more sombre, lacking its bright pink underparts. It has a black cap, face, wings and tail; the rest being greyish or pale grey-brown. Males and females are virtually identical in appearance, though males may exhibit a faint pinkish suffusion on the belly and flanks. The contact call is a distinctive short, flute-like, melancholic whistle.
分类信息
The Azores bullfinch was first described in 1866 by British ornithologist Frederick Godman. It was formerly regarded as a subspecies of the Eurasian bullfinch (Pyrrhula pyrrhula), but was split off in 1993.

分布与栖息地
The Azores bullfinch is now largely restricted to a small area (c. 580 hectares [1,400 acres])) of native laurisilva forest at the eastern end of São Miguel, 300–800 m (980–2,620 ft) asl (above sea level), mainly centred on Pico da Vara in the Serra da Tronqueira range, but also seasonally (September to December) around Salto do Cavalo, further westwards in the range. The latter population probably comprises juveniles following post-fledging dispersal. The species has never been recorded from the western end of the island.<p>Necessary for the recovery of the Azores bullfinch is to restore its available ecological enclaves in the northern archipelago of Macaronesia. The process of species decline, which a significant portion of other endemic Azorean flora is also suffering, is favored by the expansion of invasive alien plants. Projects dedicated to saving the Azores bullfinch include the restoration of original laurel forest habitat in the eastern monteverde of São Miguel.

Zappey's Flycatcher
Cyanoptila cumatilis
Very similar to Blue-and-white Flycatcher (breeding grounds do not overlap). Females and juveniles are essentially unidentifiable while on migration unless seen with an adult male, which is radiant, electric blue above and white below, lacking the contrasting black throat and breast of Blue-and-white, instead transitioning more smoothly from blue to white. Pale gray smudging on the flanks, while more difficult to see, can also serve to differentiate the two. Song is a thrush-like series of bright, slightly slurred warbles and whistles. Breeds in submontane mixed forests in northern China; wintering grounds little-known, but presumably at a similar altitudinal range in evergreen forests.
Mottle-cheeked Tyrannulet
Phylloscartes ventralis
Small olive-yellow flycatcher with a long slender tail, which is often held cocked. Olive above and yellow below with a pale eyebrow, a white chin, and two pale wingbars. Found in montane forests including Araucaria forests, where it forages actively in the middle and upper layers of the forest often with mixed-species flocks. The song is short and high-pitched.
Brown-hooded Gull
Chroicocephalus maculipennis
Handsome hooded gull of southern South America and Falklands. Commonest in coastal areas, but also ranges inland to lakes, rivers, dumps, and fields. Extensively to wholly white wingtip is distinctive in all plumages. Breeding adult has dark brown hood (often looks black at a distance) with a white eyering. Immature and nonbreeding plumages have a distinct dark spot on cheeks. Compare with Gray-hooded Gull, which occurs with Brown-hooded in Argentina and the larger Andean Gull, which overlaps locally in central Chile.
