Speckle-breasted Wren
Pheugopedius sclateri
A distinctive medium-sized wren found from central Colombia to northwestern Peru. Occurs from sea level to around 1,600 m, locally higher. Warm brown above with a white eyebrow, streaked black-and-white face, and black spotting on breast. Tail and undertail coverts have strong barring. Pairs are found in the dense understory of scrubby woodland and edges. Listen for the loud sweet song phrases and the distinctive call, like running your finger up a comb.
Identification
The nominate P. s. sclateri is 14.5 to 15.5 cm (5.7 to 6.1 in) long and weighs 20 g (0.71 oz). Adults have a reddish brown crown and a medium brown back and rump. Their tail has alternating gray and dull black bars. They have a narrow white supercilium and a dark eyestripe; the sides of the face and neck are mottled black and white. Their underparts from the chin down through the lower belly have fine black and white bars. The lower belly and flanks have bars but they are more diffuse, and the flanks also have a buff wash. Juveniles are similar to the adults but their underside's bars do not go as far down the belly.<p>P. s. columbianus is 13 to 14 cm (5.1 to 5.5 in) long. Adults have uniform brown upperparts with a rufous tinge to the crown and their tails have broad dark bars. They have a narrow white supercilium. Their face and most of their underparts are white with black bars and spots; the flanks are dark buff.<p>P. s. paucimaculatus is 13.5 to 15.5 cm (5.3 to 6.1 in) long. Males average 12.7 g (0.45 oz) and females 10 g (0.35 oz). Adults have uniform brown upperparts with black bars on the tail. They have a narrow white supercilium and black and white speckled cheeks. Most of the underparts are whitish, with a heavily black-speckled breast, and the flanks are rufescent. The juvenile is similar but its breast is not as heavily speckled.
Taxonomy
The speckle-breasted wren has at times been treated as conspecific with rufous-breasted wren (P. rutilus) and spot-breasted wren (P. maculipectus). They do form a superspecies.<p>The International Ornithological Committee (IOC) and the Clements taxonomy recognize three subspecies. The names in parentheses are from Clements.<p>BirdLife International (BLI) treats all three subspecies as separate species and calls them the "Maranon", "Colombian", and "speckle-breasted" wrens.

Range and habitat
The subspecies of speckle-breasted wren are found thus:<p>The three subspecies occur in somewhat different habitats. P. s. sclateri inhabits the undergrowth of dry forest up to approximately 1,600 m (5,200 ft) elevation. P. s. columbianus inhabits the thick understory of forest borders and open woodland at elevations between 1,300 and 2,000 m (4,300 and 6,600 ft). P. s. paucimaculatus inhabits the interior and edges of deciduous semi-humid woodland, especially those with a dense understory. It ranges from the lowlands to approximately 1,600 m (5,200 ft) in Ecuador and to 2,000 m (6,600 ft) in Peru.

Behavior
P. s. paucimaculatus is known to eat insects, and the other two subspecies are assumed to also be mostly or completely insectivorous. It and P. s. sclateri are known to forage in the understory, though the former also sometimes goes higher. They are usually in pairs and often join mixed-species foraging flocks. P. s. columbianus is assumed to have a similar strategy.<p>Only P. s. paucimaculatus' breeding phenology has been studied. Its breeding season apparently spans from April to September, based on the dates of observation of an active nest, of adults carrying food, and of recent fledglings. The one described nest was enclosed, made from sticks, vines, leaves, and lichen, and was on the ground; it held four eggs.<p>The songs of the three subspecies of speckle-breasted wren have no known differences. The song is "a series of fast, repeated phrases" sung by both sexes [1]. The call is "a musical rising trill" [2].

Other Birds
Chiloe Wigeon
Mareca sibilatrix
Handsome and distinctive duck. Sexes look similar, but male averages brighter. Note the striking face pattern (duller on young and on adults in late summer), bright rusty sides, and bold white forewing patches that show in flight. Often common in wetlands, marshes, at lakes, and along river mouths. Associates readily with other waterfowl, but more often seen on shore, grazing in grassy areas.
Papuan Treecreeper
Cormobates placens
A medium-sized creeping bird of montane forest. Mainly a dull, gray-brown color with pale flecks on the flanks, a paler throat. Female has a rufous moustache stripe. The only treecreeper on New Guinea. Climbs up a trunk, then flies down to the base of another trunk. Sometimes followed by a fantail. The only other similar colored birds with this behaviour are the sittellas, which are distinctively smaller and most have a streaked back. Call, a level series of piping notes which increase in volume.
Sandy Scops-Owl
Otus icterorhynchus
Small owl of west and central African rainforest. Note the white slash on the shoulder, the small ear tufts, and the pale spots on the underparts. The overall color varies from brown in the western part of the range to cinnamon in the east. Local and scarce in lowland rainforest. Usually detected by its vocalization, a long descending whistle, repeated with pauses of several seconds. Fairly similar in appearance to African Scops-Owl, but is brown or rufous rather than gray, has spotted rather than striped underparts, and is found in different habitat.
