Dwarf Fruit-Dove
Ptilinopus nainus
A tiny fruit dove of lowland and foothill rainforest. Mainly green with bright yellow vent. Male has a distinctive purple mark across the chest and a pale crescent above the shoulder. Often found in pairs and sometimes mixing with other fruit-dove species. Feeds on fruit and also nectar. Similar to female Claret-breasted and White-breasted Fruit-Doves, but Dwarf Fruit-Dove is smaller and has yellow edging to the wing feathers. Call, a distinctive falling and rising, “oh-wah!” repeated several times.
识别特征
With a total length of 13–15 cm (5.1–5.9 in), it is the shortest pigeon or dove in the world, but as it is thickset, several other species weigh less. Its plumage is overall green, but with contrasting yellow undertail coverts, and narrow bars to the wings. The inner wing-coverts and secondaries are more bluish in color compared to the rest of the body. This bluish-green coloring is most prominent on the scapulars, which are the body feathers that cover the top of the wing when the bird is at rest. The males differ in color and plumage from the female. The males have a dark purple patch on the belly and tend to have a gray patch on both sides of their upper breasts. Both males and females have a yellowish-green beak and purplish-red legs, in addition to a yellow area on their abdomen and undertail coverts. Juvenile fruit doves resemble the coloring of females, but have yellow fringes on most of their plumage. Eventually this yellow fringe will disappear, and the birds will resemble their gender colorings. These fruit doves will often be found in pairs of their own species, and sometimes intermingling with other fruit dove species.<p>Dwarf fruit doves will communicate with each other using a high-pitched, slow, soft, and prolonged up slur. With a one-second pause, the sound is repeated about six times. Their call resembles a “oh-wah” sound.

Yellow-throated Cuckoo
Chrysococcyx flavigularis
A small green-backed forest cuckoo of West and Central Africa. Males have a distinctive bright yellow throat and a brown-and-black barred belly, while females lack the yellow throat and have a brown-and-black barred face, throat, and breast. Can be located by its distinctive song, which is a series of up to 10 or more rapidly delivered clear whistles that speed up before quickly fading. Alternate call is an often overlooked “dwuit-tew” or “wait here.” Usually outnumbered by African Emerald Cuckoo, in which males have yellow bellies and green heads and females have more of a black-and-white barred appearance.
Rufous-tailed Foliage-gleaner
Anabacerthia ruficaudata
A medium-sized bird, brownish above and pale buff below, with a bright rufous tail and a distinctive buffy line behind the eye. Found in tall rainforest, where it occurs mainly in the midstory and canopy. Feeds on insects and forages actively, often investigating dead leaf clusters and other accumulations of detritus. Song is fairly fast series of nasal upslurred notes, sometimes preceded by a fast series of sharper nasal calls. Most similar to Rufous-rumped Foliage-gleaner, but Rufous-tailed is somewhat smaller and usually in higher levels in the forest. Note also Rufous-tailed’s brown rump contrasting with the rufous tail.
American Dipper
Cinclus mexicanus
Unmistakable plump passerine. Slaty-gray overall with a browner head. Juveniles are slightly paler below than adults. Forages for invertebrates by walking underwater. Inhabits fast-moving rocky streams in western North America, from Alaska to Panama. Often nests under bridges. Unique shape, behavior, and strict habitat preferences make American Dipper unlikely to be confused with any other species.
