Tolima Dove
Leptotila conoveri
Shy dove found only in Andean cloud forest in central Colombia. The dull reddish-purple color on neck and breast, gray crown, and pale eye separate it from the much more common and widespread White-tipped Dove. Usually stays well hidden, but sometimes comes out into the open in clearings and along quiet roads, especially early in the morning. Gives low, well-spaced coos.
识别特征
The Tolima dove is 22.5 to 25 cm (8.9 to 9.8 in) long. It has a blue-gray to dark gray crown and a reddish hindneck with a violet gloss. Its upper mantle is reddish gray overlain with iridescent violet and the rest of the upperparts are dark gray with purple iridescence. The wings are browner and the tail is slaty with white tips on the outer feathers. The throat is white and the breast reddish pink with a sharp division between it and the buff lower breast and belly.
分类信息
The Tolima dove is monotypic. It is closely related to the grey-chested dove (Leptotila cassinii) and ochre-bellied dove (Leptotila ochraceiventris), and might form a superspecies with them.

分布与栖息地
The Tolima dove was believed to be limited to the eastern slope of Colombia's central Andes in Tolima and Huila Departments. In 2014 it was discovered in Cundinamarca Department in the eastern Andes. It mostly inhabits the interior and edges of humid subtropical forest, in an elevation range of 1,200 to 2,500 m (3,900 to 8,200 ft). However, in the canyon of the Combeima River it is found in disturbed areas including coffee plantations and near human habitation.

行为
The Tolima dove has been reported as feeding mainly on Bocconia frutescens seeds but nothing else is known about its diet or foraging habits.<p>Observations of Tolima doves in breeding condition, eggs, and nestlings indicate a nesting season that extends at least from March to September. It builds a shallow bowl nest of heavy twigs in bushes or small trees, usually no more than 2 m (6.6 ft) above the ground. The clutch size is two eggs.<p>The Tolima dove's song is "a single slightly over-slurred note “wooOOOooo”, with a clear emphasis in the middle."

White-chinned Petrel
Procellaria aequinoctialis
Common, rather large dark petrel of the Southern Ocean; regular migrant north into Humboldt Current. Usually looks wholly blackish with a pale, ivory-colored bill—the white chin is often just a few feathers and frequently is difficult to see in the field, although it can be more extensive, especially on Atlantic and Indian Ocean birds. White-chinned is obviously larger than dark-billed Sooty Shearwater and much smaller than giant-petrels, which have huge pale bills. Pale bill tip distinguishes White-chinned from similar Westland and Parkinson’s Petrels, which have dark bill tip.
Japanese Night Heron
Gorsachius goisagi
A small brown heron with awkward-looking, hunched appearance. Occurs in dense, damp lowland and foothill forests next to bodies of water, where it hunts prey in dense cover. Paler crown and weaker crest than similar Malayan Night-Heron and lacks the white wingtips of that species. Shy and difficult to see; most readily observed during migration, when it sometimes visits more open habitats. Gives hooting calls at regular intervals, especially in early evening.
Nicobar Imperial-Pigeon
Ducula nicobarica
A large pigeon with greenish-brown upperparts, gray head, and gray underparts. Occurs in small flocks that feed on fruits and berries in the canopy. Found only in the evergreen forests of the Nicobar Islands. Similar to Green Imperial-Pigeon, but the Nicobar Imperial-Pigeon is darker above and grayer below, with a brown vent. Calls include burbling notes and a deep, low growl.
