Thick-billed Siskin
Spinus crassirostris
Scarce and local throughout its range, and rarely encountered. Found in varied scrubby montane habitats, especially Polylepis groves. Feeds in shrubs and on the ground, often in pairs and small groups; associates readily with other siskins. Both sexes resemble the much commoner and more widespread Hooded Siskin (absent in central Chile), but Thick-billed Siskin is stockier with a relatively large, deep bill. Varied songs and calls overall rather similar to other siskins.
识别特征
The thick-billed siskin has an adult length of between 13.5 and 14 centimetres (5.3 and 5.5 in). The bill often has a silvery base and is noticeable thicker than other related siskins. The male closely resembles the hooded siskin (Spinus magellanicus) and has a black head and throat, greenish-yellow upper parts (sometimes streaked with dark markings) and bright yellow underparts. It differs from the hooded siskin in having a whitish-grey midbelly. The immature male has a black head but is otherwise less conspicuous than the mature male, being more greyish-olive above and greyish below. The female is similar but lacks the black head and is altogether much duller in appearance, more greyish-olive, with paler underparts.

Rufous-throated Antbird
Gymnopithys rufigula
Medium-sized antbird of rainforest understory, almost always encountered near swarms of army ants, which it follows to pursue insects flushed by the ants. No similar species in range; key field marks are pale legs and striking bare eyering, which appears white in dim forest understory. Frequently seen perched on vertical stems within a meter of the ground. Usually heard prior to being seen; gives low churring calls while foraging and a sharp doubled note when chasing other birds.

Utupua Whistler
Pachycephala utupuae
Brightly-colored male has a bright golden belly, a black chest band and head, and a clean white throat. He appears to have a black “shawl” with golden wings and a black tail. Female is considerably duller, being olive-brownish above and yellow below, with a pale throat and brown breast. Endemic to Utupua, in the southeastern Solomons, where it is found in most island habitats, though avoids villages. Voice includes a sequence of sparsely spaced, thin, uninspired whistles. Formerly grouped with Vanikoro Whistler and Nendo Whistler under “Temotu Whistler.”

Shelley's Starling
Lamprotornis shelleyi
A small dark starling of dry country. The upperparts are iridescent, with a blue sheen on the head and green on most of the wing. Also note the chestnut underparts and the yellow-orange eye. Found in dry thorn savanna and thorn scrub, usually in small wandering flocks, often with other species of starlings. Similar to Hildebrandt’s Starling, but slightly smaller and darker overall, with a deeper rufous belly and a less contrasting green wing. Also reminiscent of Superb Starling, but doesn’t have a white chest band. Gives mewing calls, often in a long, continuous series.
