Diamond Dove
Geopelia cuneata
Tiny gray dove with a plain neck and chest, and an obvious red eyering. This species has tiny pale spots on folded wings. The tail is quite dark, long and pointed (much longer tail than the similar Peaceful Dove). More common inland and in northern Australia, where it can be abundant in arid grassland areas.
识别特征
They are small pigeons with a length of 19 to 21 centimeters or 9 to 11 inches. Regardless of sex, they have white spots and black edges on their wings, red eyes and orange eye-rings. The sexes look similar except the female's eye ring is less vivid and has more of a brown colour to the plumage. The male's head, neck, and breast are light blue-grey. The bill is a dark grey colour. The abdomen is a creamy colour while the back and tail is a brown-grey colour. The legs and feet are pink. The juveniles have a light grey bill; the iris and eye ring is fawn in colour; the feet and legs are grey; the breast is grey and does not possess any white spots on their wings.[citation needed]<p>Regardless of its astoundingly small size (weighing only about 35 g), it has a great tolerance to high heat levels due to adaptations in body temperature, metabolism, respiration, water balance, and behaviour.
分类信息
English ornithologist John Latham first described the diamond dove in 1801. The common name "diamond" is a reference to the white speckles on its wings.

行为
The diamond dove is often seen on the ground, where it runs with a waddling gait. Its flight is strong, direct, and sometimes undulating. The wings can make a whistling "frrr" noise when flying.<p>Diamond doves tend to be seen in pairs or small groups feeding off the ground. They feed off seed mostly from grasses. They will also eat ants.[citation needed]<p>The doves tend to breed after rain but mostly in spring in Southern Australia. Nests are usually built from interwoven grasses and/or twigs, and are fragile in construction. Two white eggs are usually laid and incubated for 13 to 14 days. Their chicks are fast to grow, and are usually fully feathered and flying by two weeks.[citation needed]<p>They are known to have a variety of calls. The calls sound mournful, slow and have a soft, pleasant falsetto quality to them. Two calls consist of two long coos followed by a pause and then a long, short and long coo. Sometimes they call two long coos. The alarm coo consists of a few short but loud coos.[citation needed]

Diamond doves are not listed as threatened on the Australian Environment Protection and Biodiversity Conservation Act 1999.

Rufous Hornbill
Buceros hydrocorax
A large hornbill of lowland and foothill forest. Body dark, with rufous thighs, chest, and neck, a whitish tail, a red casque, a long red bill, and a black face bordered behind with yellow. Females have a smaller casque, a paler eye, and no eye-ring. Southern birds have a yellow-tipped bill. Similar to the Writhed Hornbill, but Rufous lacks the black tip to the tail and has a rufous rather than black or pale head. Voice includes loud, downslurred nasal honking notes.
Orange-banded Thrush
Geokichla peronii
An unmistakable thrush with a “tiger-striped” face pattern, a white throat, a broad orange chest band, orange flanks, a white belly, and extensive bold white wing markings. Juveniles show rusty wing spots, pale streaking, a black and buff breast band, and black flank spots. Forages singly or in pairs on the ground and in trees, in forests and wooded patches within lowlands and hills. Confined to the eastern Lesser Sundas. Gives a rich, musical song characteristic of thrushes, with sequences of fluty upslurred and downslurred whistled notes comprising repeated phrases mixed with softer, chuckling sounds and thin, high-pitched notes.
Black-and-red Broadbill
Cymbirhynchus macrorhynchos
Utterly unmistakable inhabitant of waterside and riverine lowland evergreen forests, mangroves, and plantations. Midnight black with long white slashes on each wing, wine-red underparts, and a black chinstrap. Bulbous bill is glowingly powder-blue with warm tinges of orange and greenish-yellow. During the breeding season, the pendulous nests of this species can be quite obvious, hanging over forested waterways. Voice is nasal and generally unpleasant-sounding, consisting of odd low mechanical rasps.
