Bannerman's Shearwater
Puffinus bannermani
A small black-and-white shearwater with relatively broad wings and a long rounded tail. Underwing very white, contrasting with darker smudgy marks along the leading edge of the wing. Two dark smudge marks are often visible at the collar, extending down from the hood. Somewhat similar to Bryan’s Shearwater, but much larger, and white does not extend above the eye, creating a darker-faced appearance. Also lacks the distinctive rapidly fluttering flight of Bryan’s.

Other Birds
Yellow-breasted Bowerbird
Chlamydera lauterbachi
A rather drab bowerbird of forest edge and cultivation from the lowlands to the mid-mountains. Olive-brown back and wings with pale-edged feathers giving a scaled effect. Yellow belly, streaky throat and face. Makes a unique 4-walled bower. Similar to Fawn-breasted Bowbird, but Yellow-breasted Bowerbird has a yellow rather than buffy belly and an unstreaked crown. Call, a loud, downward “kyew!”.
Common Sandpiper
Actitis hypoleucos
Small bicolored sandpiper which often bobs its tail in a distinctively wagtail-like manner. Plain brown with white underparts; distinguished from bulkier and rounder-headed Green Sandpiper by a prominent white spur at the shoulder. Found in a variety of wetland habitats; breeds on stony ground along rivers and lakeshores, with migrants occurring on muddy and rocky substrates from concrete canal banks to channels in tidal mudflats. Mainly found as singles or in small groups, not in flocks or mixed with other species.
Mourning Warbler
Geothlypis philadelphia
Robust warbler found near the ground in thick vegetation. Yellow below with blue-gray head and olive back. Adult males show black chest patch. Females are paler gray on the head; immatures are more olive-toned with a yellowish throat. Breeds in brushy, weedy clearings within mixed or coniferous forest. Often favors raspberry thickets. Tends to stay hidden in low vegetation, so can be difficult to see. Listen for its rolling song, “churry churry churry chew.” Most similar to MacGillivray’s Warbler, but little range overlap, and Mourning has somewhat shorter tail and lacks bold white eye-arcs. Also frequently confused with Common Yellowthroat, especially in fall, but Mourning is larger, with heftier pinkish bill, and brighter yellow underparts.
