Waigeo Shrikethrush
Colluricincla affinis
A chunky bird with a notably thick pale bill. Dark brown on the upperparts and paler brown below, with some blurry breast streaking. Found in the understory and at middle levels of humid forest, including secondary forest. Rich, melodious, variable song consists of several penetrating whistles, generally in an up-and-down pattern. Calls include “chek” and “whit” notes. Somewhat similar to Rusty Pitohui, but smaller, lacking rufous underparts, with a dark rather than pale eye.
分类信息
This species was formerly considered a conspecific member of the little shrikethrush complex. Genetic investigations of New Guinea populations of the little shrikethrush indicate high levels of genetic divergence, suggesting it comprised more than one species.

Eurasian Tree Sparrow
Passer montanus
This common Eurasian species is a close relative of the House Sparrow. Slightly smaller than House Sparrow with entirely rufous cap, black and white cheek, and limited black in the throat. Males and females are similar. Typically found in noisy small flocks, often in more natural areas than concrete-loving House Sparrow; calls are often higher-pitched than those of House Sparrow, and has a slightly slower chatter. Feeds on seeds. Introduced to a small region in the central U.S. and southeast Australia.
Whiskered Tern
Chlidonias hybrida
Small buoyant tern. Breeding adult has distinctive dark smoky gray body and contrasting white cheeks (can look like broad white "whiskers" in flight) underneath a black cap. Nonbreeding plumage pale silvery gray overall with a faded shadow of the cap; juvenile has dark-checkered back. Note rather stout bill (albeit thinner than Gull-billed Tern) and square tail; compare to Common, Roseate, and Arctic Terns. Feeds by picking from surface, not splash-diving like typical terns. Common around wetlands, lakes, and rivers.
Blue Whistling-Thrush
Myophonus caeruleus
Large, found along streams in forested hills and mountains. Dark purple with tiny silvery spots on head, back, and wings. Bill color varies with range: dark in central and eastern China and parts of mainland Southeast Asia, bright yellow in populations elsewhere. Frequently fans tail while standing on an exposed perch such as a waterside rock or overhanging branch. True to its name, it does whistle: a long piercing note that carries well over the sound of rushing water.
