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

Papuan Owl
Uroglaux dimorpha
A rare and little-known owl of lowland and foothill forest. Medium-sized with a small-headed appearance. Dark brown with barred back and tail. Pale underparts with long, sparse streaks and finer streaking on the head and throat. Feeds on a variety of prey including rodents, birds and insects. Similar to Barking Owl, but Papuan Owl is slightly smaller with more sparse streaking on the belly and lacks the white flecks on the back. More easily told apart by voice. Voice, a medium-pitch, fluty “hoot hoot” delivered slowly.
Fatu Hiva Monarch
Pomarea whitneyi
A distinctive large glossy-black flycatcher with a pale bluish-ivory bill. Bushy feathers give an eyebrowed appearance. Dependent on native moist forest between 50 and 700 meters of elevation. Common call is said to be a “kik-kik-kik.”
Fire-tufted Barbet
Psilopogon pyrolophus
Beautiful emerald-green barbet. Note silvery cheeks, white forehead, and black chinstrap; namesake reddish tuft above the base of the bill is small and often difficult to see from a distance. Bulbous horn-colored bill has a large dark smudge down the center. Strange song is a loud accelerating creaking that is reminiscent of rusty machinery revving up.
