Satin Bowerbird
Ptilonorhynchus violaceus
Large plump bowerbird with short bill. Adult males are entirely dark glossy blue-purple color with a pale bill and bright violet eye. Adult females and immatures are primarily green and brown, with blue/pink eyes and scalloped underparts. This species can be quite loud and vocal (screeches, hisses, yowls). It is often encountered in pairs or small groups. Males are well-known for building a large bower decorated with small blue objects. Found in rainforests and wet eucalypt forests of eastern Australia.
识别特征
Mature males have violet-blue eyes and are uniformly coloured black, however, light diffraction by the surface texture of the feathers results in an almost metallic sheen giving a deep shiny blue appearance. Immature males are coloured and marked the same as females and are often mistaken for them.<p>Females might be mistaken for the green catbird or spotted catbird with distinctively green/brown or otherwise entirely brown upper body and lighter under body with a distinct reticulated or scalloped pattern, but with very striking blue eyes.

Black-throated Sparrow
Amphispiza bilineata
Evidence that not all sparrows are dull, Black-throated Sparrow is a sharp-dressed denizen of open, shrubby desert. Gray-brown overall with distinctive black-and-white face pattern, dark tail with white corners. Streakier juvenile shows a hint of adult's face pattern, especially white eyebrow. Typically found on or near the ground in pairs or small flocks. Tinkling song with short trills and chips.
Wahlberg's Eagle
Hieraaetus wahlbergi
A small brown eagle with a slighter head and weaker beak than in larger brown eagles. A short crest gives the head a distinct squared-off look. In flight its crucifix-ilke shape is distinctive: straight-edged wings and a long straight-edged tail are most often held closed. Also occurs in pale and intermediate morphs, but dark, chocolate-brown coloration is the most common. Movements are complex, but it is mostly an intra-African migrant, breeding in the south (August to March) and occurring year-round farther north. Inhabits woodland, savanna, and farmland, hunting a broad range of vertebrate and insect prey both from perches and on the wing.
Saunders's Tern
Sternula saundersi
Tiny, pale coastal tern. Has a yellow bill and neat black head markings in breeding plumage, and a dark bill and messier head markings in non-breeding plumage. Found on coastal sand bars and mudflats, and sometimes on the open ocean. Extremely similar to Little Tern. In breeding plumage, Saunders’s Tern can be identified by the fact that the small white patch on its forehead is squared off and doesn’t extend behind the eye. In non-breeding plumage, the two species may be indistinguishable.
