Australian Fairy Tern
Sternula nereis
Very small coastal tern with forked tail. Nests on sandy beaches, where it is sensitive to disturbance. Very similar to Little Tern, which overlaps in range in parts of southern Australia. In breeding plumage, note yellow bill (in southern Australia lacking black tip) and orange-yellow legs. In contrast to Little Tern, Fairy has a gap between the black in front of eyes and the bill (in breeding Little, the black extends to the bill). In nonbreeding plumage, bill much darker. Hunts by flying low over the water and plunging down to snatch prey from the surface. New Zealand subspecies very rare and breeds only at four sites on the east coast of the southern Northland.
识别特征
The fairy tern is a small tern with a white body and light bluish-grey wings. A small black patch extends no further than the eye and not as far as the bill. In the breeding plumage both the beak and the legs are yellowish-orange. During the rest of the year the black crown is lost, being mostly replaced by white feathers, and the beak becomes black at the tip and the base. The sexes look alike and the plumage of immature birds is similar to the non-breeding plumage. The total length of the fairy tern is about 25 cm (10 in).

行为
The fairy tern mainly feeds on fish which it catches by hovering over the sea before plunging beak first into the water to grab its prey. It seldom goes far out to sea but is often to be seen where predatory fish are feeding on shoals of small fish. It also consumes crustaceans, molluscs and some plant material.<p>Breeding takes place in the spring in colonies on sheltered beaches on the mainland or on offshore islands. The nest is just above high-water mark and is a scrape in the sand. One or two eggs are laid and both parents share the incubation and care of the chicks and have occasionally been seen providing post-fledging parental care.

Yellow-billed Shrike
Corvinella corvina
A large, very long-tailed streaky brownish shrike with a paler eyebrow and underparts, a rusty wing panel, and a chunky bright yellow bill and eye-ring. Resident, found in gregarious family groups and nomadic flocks inhabiting arid savanna and woodland. From a perch at middle height, it swoops onto invertebrates and small vertebrates, often on the ground. Vocalizations include a complex and varied series of noisy chatters, shrieks, and rasping buzzes, often given collectively by the group, but the main pair may also duet.

American Pipit
Anthus rubescens
Slender and drab songbird of open country. Usually grayish above and streaked below, but some lack streaks in breeding season. Distinguished from similar-looking (unrelated) sparrows by thin bill and lanky appearance with long legs. Walks on the ground with jerky motions and frequently bobs tail. Flocks are often heard as they pass overhead or flush from a barren field; listen for sharp, high-pitched call notes and look for flashing white outer tail feathers. Song, given from a perch or in flight, is an often impressively lengthy series of repetitive, high-pitched notes.

Powerful Owl
Ninox strenua
Very large dark brown-and-white owl with underparts heavily marked with dark chevrons and enormous yellow feet. Found around coastal south-eastern Australia. Roosts in large trees along creeks, gullies, in dense woodland and forest. Call is a loud double-hoot with second note slightly higher than the first.
