Lemon-bellied Flyrobin
Microeca flavigaster
Small Australian robin, gray above, lacking pale panels in folded wing and white in tail. Except in Kimberley subspecies, pale belly washed with lemon yellow. Often perches near the top of trees, calling frequently. Jacky-winter has white outer tail feathers and no yellow belly; Golden Whistler much larger, with yellow limited to lower belly. Inhabits many habitat types in northern Australia.
识别特征
The adult lemon-bellied flyrobin is around 11.5 centimetres (4.5 in) long. The sexes have similar plumage. The nominate subspecies flavigaster has lemon yellow underparts, a white throat, grey face with a white eyebrow stripe, and olive-brown upperparts. Subspecies tormenti has white underparts, more greyish upperparts, has a longer bill and tail and is larger overall. Subspecies flavissima resembles flavigaster but has a more obvious yellow tinge to the upperparts, throat, yellow eyebrow and a shorter tail, while laetissima more closely resembles flavigaster, but has a shorter tail and bill and is larger overall.
分类信息
John Gould described the species in 1843 from a specimen from Port Essington in the Northern Territory. The species name is from the Latin word flavus meaning 'yellow', and Ancient Greek gaster meaning 'belly'. Four subspecies are recognised: the nominate flavigaster is found across the top of the Northern Territory, subspecies flavissima in Cape York and New Guinea, subspecies laetissima along the central-northern Queensland coast, and subspecies tormenti in the Kimberley of northwestern Australia. The two Queensland subspecies are separated by the Atherton Tableland and Burdekin-Lynd Divide, and are possibly kept apart by a population of the jacky winter (Microeca fascinans) that replaces it in some areas. Genetic analysis shows that the two Queensland subspecies are very closely related, but that there is quite a large separation from subspecies flavigaster. Subspecies tormenti was not sampled in that study.<p>Subspecies tormenti, known as the Kimberley flyrobin, was considered a separate species for many years. It is unusual in that it lacks the yellow pigmentation of the other subspecies. Les Christidis and Walter Boles reclassified it as a subspecies, since hybrids between subspecies tormenti and flavigaster have been found in the vicinity of Cambridge Gulf—between the ranges of the two subspecies.<p>As well as lemon-bellied flyrobin, the species is also commonly known as lemon-breasted flycatcher (from when belly was thought crude), yellow-bellied flycatcher, yellow-breasted flycatcher, or brown-tailed flycatcher (subspecies tormenti).

White Hawk
Pseudastur albicollis
Spectacular, broad-winged, short-tailed hawk of lowland tropical forest. Usually seen soaring in mid-late morning or perched quietly in the forest canopy. Basically unmistakable, but beware of rare albino forms of other hawks. Plumage is white overall with black wingtips and a black tail band. Immature has more black on wings, as do adults of populations in southern Central America. Note dark eyes and pale grayish base to the bill (versus yellow on most hawks).
Eastern Phoebe
Sayornis phoebe
A drab, medium-sized flycatcher. Brownish above and pale below, often with a light yellowish wash on the belly. Watch for constant tail-wagging, and also note duller wingbars than Empidonax flycatchers. Common and familiar throughout eastern North America, wintering as far south as southern Mexico. Usually seen singly or in pairs in relatively open habitats such as woodland edge, brushy fields, or edges of ponds. Often nests under eaves of buildings and other human-made structures. An early migrant, returning north to breed much earlier than other flycatchers. Listen for its harsh “FEE-bee” song in the spring, but don’t get confused by Black-capped Chickadee’s higher-pitched, sweet whistled song of a similar pattern!
Dark-sided Flycatcher
Muscicapa sibirica
Small brown flycatcher with dark smudging on the breast and sides that lend it a “vested” appearance. Tends to prefer higher-elevation forests for breeding than Asian Brown and Gray-streaked Flycatchers but uses a variety of open forests and gardens on migration and in winter. The generally darker appearance of this species when compared to Asian Brown makes the eyering more striking.
