Blue-cheeked Jacamar
Galbula cyanicollis
Distinctive, oddly proportioned bird, with a small head and long needle-like bill. Green above and rusty below, with blue cheeks. The amount of black on the yellow bill is variable. Usually seen sitting quietly in the lower levels of humid forest and sometimes seasonally flooded forests, where it captures prey by flycatching. Sings a high-pitched “peea peea-pee-pee-te-t-t-e’e’e’e’e’e” that accelerates gradually and ends with a rattling trill.

分布与栖息地
The blue-necked jacamar occurs east of the Andes and south of the Amazon River. It is found in eastern Peru, far northern Bolivia, and in Brazil east to Maranhão and south to Rondônia and northern Mato Grosso. It inhabits the interior of terra firme and várzea forests. There it is found in the lower strata and often in small gaps. It also occurs in gallery forest in the cerrado of Brazil. In elevation it ranges up to 900 m (3,000 ft).

行为
The blue-necked jacamar's diet is a large variety of insects. It perches on exposed branches and sallies from there to catch its flying prey.<p>Two blue-necked jacamar nest burrows were found in arboreal termite nests in Brazil, one in June and the other in October; each held two eggs. Birds in breeding condition were found in September.<p>The voice of the blue-necked jacamar is essentially the same as that of the yellow-billed. A song is here [1] and a call here[2].

Western Yellow Robin
Eopsaltria griseogularis
Very small songbird found in forests of southwestern Australia as well as the Eyrean Peninsula of South Australia. Gray above, bright yellow below, with gray upper breast and off-white throat. This species perches on low branches and on the side of tree trunks before flying down to the ground to capture prey. Yellow rump and pale stripe in wing obvious mostly in flight. Differs from Eastern Yellow Robin by its gray breast (also note range). Voice is a slow repetitive "chew-chew-chew" whistle; also gives a rough, chattering, scolding call.
Gray-crowned Tetraka
Xanthomixis cinereiceps
Attractive, medium-sized tetraka. Green back, gray head, white throat, and yellowish underparts. Madagascar endemic that is found in eastern rainforest at middle and high elevations. Inhabits the mid-story, most often feeding by creeping along mossy branches like a woodpecker. Frequently joins flocks with tetrakas and other species. Call is a series of high, silvery, sputtered “sit” notes. Separated from Spectacled Tetraka by its smaller size, brighter underparts, gray head, and tree-creeping habits.
Rufous-browed Peppershrike
Cyclarhis gujanensis
A large chunky vireo, widespread in tropical and subtropical wooded habitats. Forages sluggishly, mainly at mid-upper levels, sometimes joining mixed-species feeding flocks. Plumage varies across its range, but all populations have a very stout pale bill, a rusty eyebrow, and pinkish legs; underparts vary from bright yellow (as in mainland Mexico and Central America) to dingy yellow (as on Cozumel Island).
