River Lapwing
Vanellus duvaucelii
The black, gray, and brown coloration of this medium-sized shorebird makes it unmistakable. Raises black crest when displaying. As the name suggests, this species is primarily tied to rivers, where it is often seen foraging in pairs on riverbanks or exposed islands. Calls shrilly and loudly, both during display and when alarmed.
识别特征
The river lapwing is 29–32 cm long. It has a black crest, crown, face and central throat and grey-white neck sides and nape. It has a grey-brown breast band and white underparts with a black belly patch. The back is brown, the rump is white and the tail is black. This is a striking species in flight, with black primaries, white under wings and upper wing secondaries, and brown upper wing coverts.<p>Adults of both sexes are similarly plumaged, but males are slightly larger than females. Young birds have the brown tips to the black head feathers, a sandier brown back, and pale fringes to the upperpart and wing covert feathers. The call of the river lapwing is a sharp tip-tip or did-did-did.

Little Raven
Corvus mellori
Australian crows and ravens are challenging to identify; concentrate on call, throat-hackles, behavior, and location. Calls usually fairly fast and lack the drawn-out wail typical of Australian Raven. Long throat hackles lend it a slightly bearded appearance. Often flicks wings when calling. Inhabits a broad area of southeastern Australia. The default crow/raven in Adelaide and Melbourne and forms very large flocks in high-elevation areas like the Australian Alps.
Bronze-olive Pygmy-Tyrant
Pseudotriccus pelzelni
A tiny, rotund flycatcher found singly in the understory of montane forest from Panama to Peru. Very nondescript plumage: darker olive above with a dull tawny breast and yellowish belly. Looks uniformly brownish in bad light. Usually stays low, where it perches quietly and sallies out to glean insects. Often detected by its snapping sounds and whirring wingbeats. Occurs from around 700–2,000 m, typically lower than Rufous-headed Pygmy-Tyrant but some elevation overlap.
Tawny Pipit
Anthus campestris
Large, slim, sandy-colored pipit with a long and broad eyebrow, a prominent dark area in front of the eye, sparsely streaked back and breast, and a long and pointed pinkish bill. Juveniles are more spotted and may recall other large pipits in wintering areas. Rather distinctive in its wagtail-like stance and foraging behavior. Usually found feeding on the ground in open habitats, sand dunes, dry grasslands, and gravel pits. Call is a harsh "tschlip".
