Lemon Dove
Aplopelia larvata
Dark, medium-sized dove with a pale face. Shows paler gray corners of the tail in flight. Varies geographically; most eastern and southern African birds have rufous underparts, while western and central African birds are gray below. Shy understory species that is most often seen on the ground inside thick forest. Often not noticed until it noisily flies away. Call is a deep hoot, usually delivered in a slow series, though sometimes in a quick series. Similar to Delegorgue’s and Bronze-naped pigeons but inhabits the understory and has a pale face.
识别特征
The lemon dove is fairly small, measuring 24–30 cm (9.4–11.8 in) in length and weighing 81.7–150 g (2.88–5.29 oz). Adult males have a plumage that is dark brown above, glossed green on sides of neck, and cinnamon brown below. As noted, they have conspicuous white face markings. The feet, iris and orbital skin are red, the bill is black. Females and young males are generally similar, with a lighter brown plumage and dull grey facial markings. The males of western African subspecies have a dark grey plumage.
分类信息
It differs from the other African pigeons of the genus Columba by its terrestrial habits and the white face and forehead of adult males; it is therefore sometimes separated in the genus Aplopelia. Some treat the Gulf of Guinea populations (São Tomé lemon-dove) as a separate species C. simplex (or A. simplex), others as subspecies of C. larvata. In the latter case, the species as a whole may be called simply lemon-dove, and if Aplopelia is considered a valid genus it would then be monotypic.

The lemon dove has a very wide range and is distributed in montane forests in sub-Saharan Africa, ranging for example from some 100 to 3,000 metres (330 to 9,840 ft) ASL in eastern Africa. The diet consists mainly of various small fruits, seeds, molluscs and insects. The female usually lays two creamy white eggs.

Oahu Elepaio
Chasiempis ibidis
A small flycatcher of forested habitats on Oahu. Adults are brown above, whitish below, and have white wingbars, rump, and tail tips. Immatures are reddish brown and have buffy wingbars. Uncommon and local on Oahu, more numerous in valleys. Bold and curious; not afraid of people and may follow hikers. Often holds tail cocked up at an angle. Male song is a shrill “El-eh-pie-oh” for which the species is named. Both sexes give a variety of soft calls and scolding notes. Responds to pishing and squeaking.
Yellow-eared Bulbul
Pycnonotus penicillatus
Medium-sized, plump green bulbul with a yellow belly and distinctive head pattern with yellow tufts behind each eye, white tufts above each eye, and white horns sticking up from the base of the bill. Found in small parties in the canopy of hill forests and adjacent woods and gardens. Conspicuous head pattern of Yellow-eared Bulbul differentiates it from Black-headed Bulbul, which has an unmarked, dark head. Frequently given call is a harsh trill. Song involves a series of high “whit”, whip-like notes.
Rufous-bellied Seedsnipe
Attagis gayi
Chunky, generally uncommon, rather grouselike bird of the high Andes. Found in pairs or small groups on bogs, stony slopes, and in bleak moorland of puna and páramo zones. Lacey “chainmail” pattern to upperparts is beautifully cryptic, and birds sometimes freeze when alarmed making them more difficult to see. No similar species in range; note the short stout bill and rusty underparts. Flight strong and fast, and flushes with loud shrieking choruses.
