Rufous Piha

Lipaugus unirufus

Uncommon in humid evergreen forest of tropical lowlands, where lives mainly at middle to upper levels in forest canopy. Presence often revealed by loud whistled “PEE-HAH” calls, which can be given in response to loud noises such as a sharp handclap. Often perches still and rather upright for long periods, sallying out occasionally for fruit and small invertebrates. Plumage bright rusty overall, with paler eyering and slightly bushy face. Rufous Mourner looks very similar but smaller and sleeker.

识别特征

The adult rufous piha is about 23.5 cm (9.3 in) long and the sexes look similar. The upper parts are a uniform reddish-cinnamon and the underparts are similar but a slightly paler shade, the throat being the palest part. The bill is broad and either flesh-coloured or brown at the base, and there is sometimes a slight ring round the eye. This bird could be confused with the speckled mourner (Laniocera rufescens) but that bird is shorter and more slender, with a slimmer bill and a relatively longer tail; the male rufous piha utters various piercing, whistling calls.

行为

The rufous piha breeds between March and August in Costa Rica, there probably being two clutches in the year. The diet consists largely of fruits, such as those of laurels and palms, and invertebrates such as insects and spiders. It lives in the middle and lower storeys of humid forest and seldom descends to ground level. Much of its food is plucked while it hovers, and anything gathered on the ground is carried aloft before being eaten. It often sits lethargically on a suitable perch for long periods, sallying out at intervals to snap up passing insect prey.

Malabar Flameback

Malabar Flameback

Chrysocolaptes socialis

A large, crested woodpecker with a golden-olive back endemic to wet lowland and foothill forests in southwestern India. Separated from Common Flameback and other “small-billed” flamebacks by a much larger bill, a mottled black-and-white nape instead of a black nape, and a divided black horizontal stripe below the cheek. Separated from the similarly large-billed White-naped Woodpecker by the less clean-cut face pattern, a red rump, the lack of a clean white nape, and a preference for wetter habitat. A loose participant in mixed-species foraging flocks, often detected by its loud, high-pitched trill similar to that of Common Flameback.

Plain-capped Ground-Tyrant

Plain-capped Ground-Tyrant

Muscisaxicola alpinus

Dingy, terrestrial flycatcher found only at very high elevations in the Andes. It has brown upperparts, white underparts, and a white eyebrow. Crown may show a brown tinge, but never bright chestnut like on some other ground-tyrants. Inhabits open areas away from forest. Stands vertically on the ground or a low perch, frequently flicking wings and tail, before suddenly darting after insects and other small prey.

Alle alle

Tiny waterbird, the size of an elongated grapefruit. In nonbreeding plumage, they are black above and white below with a black stripe on the side of the neck and a white comma behind eye. Short, stout bill. Horizontal posture like a football floating on the water. Dives frequently when feeding. In winter, only likely to be seen from land following the passage of a storm, otherwise stays well offshore. Found singly or in flocks. Much smaller than guillemots or puffins, with fast wingbeats and low, twisting flight that recalls a flock of sandpipers. Breeds in large numbers in Greenland and Europe; rare at alcid breeding colonies in Alaska. Birds in breeding plumage have an all-black head and chest.
