Rufous-backed Sibia

Black-and-white seabird; breeds in colonies on rocky islands and cliffs. Spends the rest of the year on the ocean, when it is seldom seen from land. Bill is shorter and thicker than Common Murre, but difficult to judge at a distance. Note blacker plumage, cleaner sides, and limited amount of white on throat in winter. These features help separate it from Common Murre and Razorbill. Usually single or in loose small groups; in the Atlantic, sometimes seen in loose association with a flock of Razorbills. Frequently dives underwater searching for fish.

Large, chunky songbird with thick hooked bill, found in mangrove vegetation of northern Australia. Male gray above, white below, with black crown connected to black-and-brown collar that encloses white throat. White throat recalls similar Rufous Whistler. Female and immature gray above, pale below, with extensive fine streaking that fades into an almost white belly. Compare Little Shrikethrush, which is smaller with a more obvious pale eyebrow. Loud whistling calls, including a two-note rising "toooo-whittt.”

A large, seemingly long-bodied warbler, mostly bright yellow with some greenish-olive above. Bill and tail long. Often perches in a flat stance, making it look banana-like. Most common in dense brush and thickets with dense tangled understory. Song is a loud and long sequence of warbled phrases and “churr” notes. Calls include harsh churring and “tchak” notes.
