Spectacled Imperial-Pigeon

Ducula perspicillata

A large pigeon with a green back, gray underparts, a darker gray head, and a bold white eye-ring. Juveniles are merely duller versions of adults. A bird of lowlands and hills, found within the canopy of forest and forest edge, normally in singles, pairs, or small groups where fruiting trees are present. Routinely heard call is a descending series of six deep hooting notes: “hoot-hoot-hoot-hoot-hoot-hoot.”

分类信息

The spectacled imperial pigeon is a species in the large genus of imperial pigeons, Ducula. Within the genus, it is most closely related to the Seram imperial pigeon, with which it is sometimes considered conspecific. These two species form a species group with the green imperial pigeon and elegant imperial pigeon.<p>The species' generic name comes from the Neo-Latin ducula (duke), while the specific epithet perspicillata is from the Modern Latin perspicillata (spectacled), derived the Latin perspicillum (lens), which is itself from the Latin perspicere (to see through). Alternative names for the orange fruit dove include white-eyed imperial pigeon, white-spectacled imperial pigeon, and Moluccan imperial pigeon.<p>It is monotypic. However, the Seram imperial pigeon is sometimes considered to be a subspecies of this species.

African Snipe

African Snipe

Gallinago nigripennis

Chunky, cryptic, short-legged, long-billed shorebird. In flight, shows much white on the outer tail and underwing. Found in thickly vegetated wetlands. Restricted to middle and high elevations across the majority of its range. Most often seen when it flushes explosively, often giving a rough “shrik” call. Display vocalization is a long accelerating series of “kik” notes, followed by a hollow booming made by the outer tail in flight display. Similar to Common Snipe, but darker and with much white in the outer tail. Also easily confused with the uncommon Great Snipe, but African is paler, lacks strong bars on the wing, and has a white rather than dark underwing.

Broad-tailed Hummingbird

Broad-tailed Hummingbird

Selasphorus platycercus

Common hummingbird of high elevations. Breeds in open woodland with meadows and scrub. In winter, found at lower elevations. Male is distinctive in range with beautiful rosy-red throat and glistening green upperparts. Female is duller with buffy sides and speckled throat. Note broadly rounded tail feathers with restricted rufous. Feeds on nectar and small insects. Visits feeders.

Western Yellow Wagtail

Western Yellow Wagtail

Motacilla flava

Widespread wagtail, favoring wet meadows, marshland, grassy and muddy lakeshores. Occurs in fields and often near livestock during migration. Like other wagtails, walks on ground and pumps its long, white-sided tail up and down. Plumage highly variable, but breeding male wholly bright yellow below, with greenish back. Male head pattern varies regionally: in U.K. has greenish head with yellow eyebrow; in northern Europe head slaty gray overall; in central and southwest Europe head blue-gray with white eyebrow; striking white-headed birds in Mongolia and northwestern China. Individuals of several subspecies may winter together. Female and nonbreeding plumages drabber and paler, with ghosting of male patterns. Songs and calls vary between subspecies, but most give some form of buzzy “dzeerdzeer” or downslurrd “tzree.”
