Canebrake Wren
Cantorchilus zeledoni
Small, skulking wren of foothills and lowlands along the Caribbean slope from Nicaragua south to western Panama. Found in forest edges, second-growth thickets, and brushy fields with cane grass. Heard more often than seen: song relatively short with bright phrases usually repeated a few times in quick succession. Note the bold white eyebrow, whitish breast, rich buffy flanks, and bright rusty tail barred black. Formerly known as Plain Wren.
识别特征
The canebrake wren is 14 cm (5.5 in) long. Adults' crowns are brown and their upperparts are brownish gray merging to olivaceous gray on the rump. Their tail is olivaceous brown with well defined darker bars. They have a white supercilium, a gray-brown stripe through the eye, and cheeks mottled with gray and off-white. The throat is off white, the chest gray, and the lower belly gray-buff. Juveniles have duller underparts and less well defined facial markings.
分类信息
The canebrake wren, with what are now Cabanis's wren (C. modestus) and the isthmian wren (C. elutus), were called the plain wren. The three were split from each other in 2016 on the basis of a 2015 publication that described their different vocalizations and genetic divergence. The canebrake wren is monotypic.

分布与栖息地
The canebrake wren is found from eastern and southeastern Nicaragua through eastern Costa Rica into far northwestern Panama, a zone whose watercourses drain to the Caribbean. It inhabits secondary forest, farmland, and canebrakes but shuns virgin forest. In elevation it ranges from sea level to approximately 600 m (2,000 ft).

行为
The canebrake wren forages low down in dense undergrowth but its diet has not been studied. <p>A study of canebrake wrens in Costa Rica found that their nesting season spanned March to August. The nests were oval balls with a side entrance, built by the female from plant fibers and lined with softer material. They were draped across thin branches in thick vegetation near the ground. Both sexes also built "dormitory" nests for roosting. The clutch size was two or three. Nestlings were fed by both parents. The nests were heavily predated; only two chicks survived from the 20 eggs monitored.<p>The members of a canebrake wren pair "sing in complex duet" [1].

White-browed Woodswallow
Artamus superciliosus
Chunky bird with broad, triangular wings and short, decurved bill. Male dark gray above, dark orange-brown below, with dark gray face and throat and white eyebrow. Female similar in pattern but less richly colored. Whitish underwings contrast powerfully with dark underparts in flight. Often forages very high up in enormous flocks, sometimes mixed in with Masked Woodswallows.
White-bearded Hermit
Phaethornis hispidus
Large gray and green hermit of understory rainforest. Gray below, green above with gray rump and white long central tail feathers. Fairly long, slightly downcurved bill, and prominent white throat and moustache. Sexes similar. Similar to Great-billed Hermit, which is more tawny brown overall (not gray), and has a red or orange lower mandible (not yellow). Found in a variety of lowland rainforest habitats; most common around forest edges, along rivers, and around heliconias.
Great Knot
Calidris tenuirostris
Medium-sized, stocky shorebird found almost exclusively on coastal mudflats during migration, seldom inland. Distinctive adult in breeding plumage has a brick-orange upperwing patch, blackish back, and chest with black mottling.
