Swallow-tailed Manakin
Chiroxiphia caudata
A very common inhabitant of humid forests. Small chunky manakin with elongated central tail feathers. Males are unmistakable with their blue bodies, black wings and head, and red crown. Females are uniformly green with a dark eye and pale legs and bill. Very noisy at the display lek where males can be heard from a long way off delivering soft “kua-a-a-a” notes.
识别特征
At a length of around 15 cm (5.9 in) and a weight of around 25.6 g (0.90 oz), this small sparrow-sized bird may be the largest species within the diminutive manakin family. Formerly, the name "swallow-tailed manakin" was used widely, but as it is misleading (the tail is unlike that of any swallow), this name has largely been abandoned for "superior blue manakin". As suggested by this common name, the male is – by far – the manakin with most blue to the plumage. The entire body is bright blue, while the wings, tail and head, except for the red cap, are black. The far duller female is greenish-brown overall. Both sexes have elongated central rectrices.<p>Juvenile males resemble the adult female, but gradually develop first the red crown, then the black face-sides, and finally the remaining plumage of the adult male. The males form leks, typically consisting of a single adult and two sub-adult males, where they sing and "dance" to attract females. This was shown in the BBC's The Life of Birds documentary series. Due to the pronounced hypergamous nature of its females, up to 90% of male blue manakins never mate.

分布与栖息地
This bird is found in north-eastern Argentina, southern and south-eastern Brazil, and Paraguay. Its natural habitats are subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and heavily degraded former forest. It is generally common in the appropriate habitats within its range.<p>One to five males live within an area of 100 meters^2, consisting of one alpha male, one beta male, and a few gamma males. Each area has four to six display perches which are horizontal vines, branches, or lianas one meter off the ground. The main display arena is cleaned by the alpha and beta males by removing moss, leaves, or twigs from the perch, making it appear whiter.

Long-bearded Honeyeater
Melionyx princeps
A long, slender honeyeater of subalpine forest and shrubland in eastern New Guinea. All sooty gray-black plumage with long tail and very long, thin, curved bill, long white, whispy beard from the base of the bill, and a yellow-orange wattle at the back of the eye. Some white scaling on the belly. Similar to Sooty Melidectes, but Long-bearded Melidectes is larger and has a white beard. Not very vocal but gives a quiet “eh eh eh” call.
Ochre-breasted Pipit
Anthus nattereri
Fairly distinctive for a pipit: blackish-brown above, including the wings, with bright golden feather edgings giving it a boldly streaked appearance. The chest and flanks are buff and lightly streaked. Look for the buffy-yellow eyebrow. Mostly encountered in well-preserved natural grasslands, favoring short grass areas that have regenerated after fires. Gives a series of sharp twittering notes ending with a slurred “eeeeeeeur.”
Palau Fantail
Rhipidura lepida
Small, with a long, often fanned tail. Mostly pale orange-red with a gleaming white throat and a black chest with gray sides. Note the small black eye mask. Mostly resident in forest, but sometimes forages in open scrub. Common vocalization is a soft whistle or raspy “me-EE-ow.”
