Pheasant Pigeon
Otidiphaps nobilis
A large ground pigeon of foothill and lower montane forest. Yellow legs, red bill, black head, underparts and tail with chestnut wings and back. Some races have a crest or pale patch on the back of the neck, and rump with a purple or green sheen. Forages on the forest floor while constantly wagging its tail. Appears more like a game bird than a pigeon, but the combination of black and chestnut make it unmistakeable. Call, an introductory note followed by a descending mournful whistle “pu-wiuuuuuu!”.
识别特征
The pheasant pigeon resembles a pheasant in external morphology, particularly in its laterally compressed tail and rounded wings. They have glossy black heads, undersides, rears and lower backs, and short rounded brown wings, and a white, green, grey, or black nape depending on the subspecies. No galliform birds occur in New Guinea, and the pheasant pigeon has filled the ecological niche of a partridge or small pheasant (while the larger Goura crowned pigeons have a lifestyle similar to larger pheasants, grouse or turkeys). It is a highly secretive species, feeding on seeds and fallen fruits. It nests on the ground below trees and bushes, laying one egg that it incubates for around four weeks. Both adults incubate and look after the young, feeding regurgitated crop milk to their young (a common practice for most pigeons).<p>They have a range of calls including a drilling-like sound, a typical pigeon cooing call and a loud "wu-huwoooooa" call that rises and falls in pitch before trailing off at the end.<p>They are found in rainforest habitats, eating fallen fruits and seeds, in the Aru Islands. As they avoid human settlements, the little that is known about their behavior comes from observation at zoos.
分类信息
The genus name makes reference to its similarities to the bustard family (Otidae). Its common name reflects its adaptation to living on the forest floor in the fashion of a South East Asian pheasant.<p>Commonly, there are four subspecies recognized that differ primarily in the presence or absence of a small crest and in the colour of the nape:<p>Some authors, however, recognize the four subspecies as four different species, a classification scheme followed by the IUCN.

Balearic Shearwater
Puffinus mauretanicus
Breeds on islands in the western Mediterranean and moves to offshore waters in Britain and southwest Europe mainly in late summer and autumn. Small, stiff-winged seabird often found in association with Manx Shearwater, which is similar in size and shape. Balearic is dark brown above, dingy pale brownish below, usually with white belly, but lacks strongly contrasting black-and-white pattern of Manx.
Middle American Screech-Owl
Megascops guatemalae
Small, cryptically patterned, yellow-eyed owl of tropical lowland forest from Mexico to Panama. Tends to stay well hidden in the understory. Cannot be identified readily by sight, but it is the only screech-owl throughout most of its range and within its habitat. Song is a purring trill that can easily be mistaken for the purring of a toad or insect. Plumage varies from grayish brown overall to reddish.
Red-necked Spurfowl
Pternistis afer
Large, chunky francolin with bare red skin on the throat and around the eye. There is much geographical variation in the presence or extent of white on the face, black-and-white streaking below, and black on the belly. Found in a wide range of habitats, including moist savanna, grassland, thickets, cultivation, and forest edge. The call is a series of rough “krek” notes, sometimes with a rollicking introduction. Bare red throat separates it from most other francolins. In areas of overlap with Swainson’s or Gray-breasted Francolins, Red-necked can be identified by black-and-white striped underparts.
