Fiscal Flycatcher
Sigelus silens
A large pied flycatcher that is most commonly mistaken for Southern Fiscal. However, the upright stance and slender unhooked bill are distinctive flycatcher traits, and the pattern of white in the flight feathers and basal windows of the tail is diagnostic. The female is duller than the male. Singles and pairs frequent a variety of open country habitats, including gardens, parks, shrubland, and woodland, where they perch conspicuously and hawk insect prey from the ground or aerially. The species is mostly silent but occasionally it utters a thin high-pitched song. The similar Southern Fiscal is more robust than the Fiscal Flycatcher, with a chunky hook-tipped bill, a white V-pattern on the shoulders, and a long tail with white outer feathers.
识别特征
This black and white bird gets its name from its resemblance to the northern and southern fiscal shrikes (previously considered one species, common fiscal), shrikes that in turn get the name from their black and white suit-and-tie appearance reminiscent of the taxman (‘fiscal’). The male may be confused with the fiscal shrikes, but the shrikes have heavy, hooked bills, white patches on the shoulder rather than the lower wing, and no white on their longer tails. The resemblance is assumed to be an example of Batesian mimicry.<p>The fiscal flycatcher is 17–20 cm in length. The adult male is black above and white below with white wing patches and white sides to the tail. The female is brown above, somewhat like an immature fiscal shrike, not black. The juvenile is like the female but duller and with brown spots and scalloping above and below.<p>The song is a weak chittering, and the alarm call is tssisk.<p>The fiscal flycatcher is larger than the male collared flycatcher, which has a white collar and lacks white wing panels.
分类信息
The fiscal flycatcher was previously the only member of the genus Sigelus but was moved to Melaenornis based on the results of a molecular phylogenetic study published in 2010.

行为
The fiscal flycatcher builds an open-cup nest from thin stems and other plant material, and lined with plant down. It is placed in a dense bush or thicket in a tree. In these respects it resembles the fiscal shrike.<p>The fiscal flycatcher feeds on insects, often taken in flight, but also on non-flying prey such as caterpillars. It may prey on the spiny caterpillars or "woolly worms" of tiger moths, after first scrubbing them on the ground or on bark, thereby denuding them of the worst of their spines. It also feeds on various species of small wild berries, such as Halleria and Chrysanthemoides, and from nectar-rich flowers such as some Aloe. In suburban gardens it commonly feeds opportunistically on domestic scraps.

Rose-crowned Fruit-Dove
Ptilinopus regina
Tiny green and yellow dove. Yellow-orange belly and vent (note Superb Fruit-Dove has a white belly and vent). Pink forehead, gray face and neck, and often a pinkish area on upper belly. Found in rainforests, but also in coastal vine forest. This species calls frequently, and typically with a long series of gradually accelerating notes.
Chivi Vireo
Vireo chivi
Plain olive-green above and whitish below with no wingbars. Variable amount of yellow on underparts, sometimes bright lemon on undertail coverts and flanks. Dark stripe through and above eye. Thicker bill than warblers, body about the same size. Widespread through South America, mainly in lowlands but also up into foothills. Very similar to Red-eyed Vireo, best distinguished by voice.
Yellow-billed Giant-Honeyeater
Gymnomyza viridis
A very large, robust honeyeater. Entirely drab grayish-olive, with yellowish wings and tail and a bright yellow bill and eye-ring. Dependent on primary mature forest, mostly in the lowlands, but less commonly above 600 meters of elevation. Similar to Northern Wattled-Honeyeater, but much larger, and overall more yellow with a distinctive pale yellow bill. Does not vocalize often, but most common call is a very, very loud, ringing, far-carrying “kee-too.”
