Arafura Shrikethrush
Colluricincla megarhyncha
A chunky bird with a notably thick bill. Shows lots of geographical variation. For example, birds in some areas are grayish with a black bill, pale face, and dull cinnamon wash below; in other areas birds are dark brown on the upperparts and rich rufous below with a pale bill. Found at low and middle elevations in a variety of humid forest, including secondary forest, swamp forest, and mangroves. Rich, melodious, variable song consists of several penetrating whistles, generally in an up-and-down pattern, often ending with one or more exuberant upslurred notes. Calls include “chek” and “whit” notes. Somewhat similar to Rusty Pitohui, but smaller, with a dark rather than pale eye. Similar in size and shape to Sooty Shrikethrush and Black Pitohui, but never as uniformly dark. Also similar to Gray Shrikethrush, but smaller and browner, with some breast streaking.

Golden-shouldered Parrot
Psephotellus chrysopterygius
Slender, long-tailed parrot restricted to a tiny range in tropical savanna woodland in far northern Queensland. Male a striking turquoise color, with red lower belly, tiny black cap, and yellow forecrown. Wings pale grayish brown with yellow band. Female primarily green with turquoise wash on face and underparts. This species digs tunnels in termite mounds in order to breed.
Broad-billed Flycatcher
Myiagra ruficollis
A long-tailed, slender songbird with fine bill. Adult rich blue-gray above, white below, with an orange throat and chest. Tail feathers are different lengths, creating staggered pattern; compare to Leaden Flycatcher, with tail feathers of roughly the same length. Inhabits mangroves and coastal forests, where it captures insects by gleaning and flycatching.
Black-and-red Broadbill
Cymbirhynchus macrorhynchos
Utterly unmistakable inhabitant of waterside and riverine lowland evergreen forests, mangroves, and plantations. Midnight black with long white slashes on each wing, wine-red underparts, and a black chinstrap. Bulbous bill is glowingly powder-blue with warm tinges of orange and greenish-yellow. During the breeding season, the pendulous nests of this species can be quite obvious, hanging over forested waterways. Voice is nasal and generally unpleasant-sounding, consisting of odd low mechanical rasps.
