Whistling Dove

Ptilinopus layardi

A unique Fijian dove. Male’s combination of bright yellow head, green body, and yellow undertail is diagnostic. Female is mostly green with a variably gray belly patch and yellow undertail. She resembles female Orange and Golden Doves, but those species do not overlap in range. Frequently heard giving two call types: a loud rising whistle followed by a metallic note, “wheEE!-chit”; and a second, more sneeze-like “nyehh.”

识别特征

The whistling fruit dove is a small dove (20 cm) that is sexually dimorphic in its velvety plumage. The plumage of the male is dark green with a yellow head and undertail coverts, the female lacks the yellow plumage. They are difficult to see in the forest canopy, but can be found due to their distinctive call, a clear rising whistle followed by a falling 'tinkle'

分类信息

The whistling fruit dove is the most primitive of the "golden doves", a small subgroup of the genus Ptilinopus which includes two other small Fijian fruit doves, the golden fruit dove and the orange fruit dove. The group was once split into its own genus, Chrysoenas.

行为

The species feeds on fruits in the forest canopy.<p>The breeding of this species has not been studied much. A nest described in 1982 was a 'loose thin platform' constructed with twig-like vines 3 m above the ground (Beckon 1982). A single nestling was described. Only the female took care of the young. If this pattern of parental care is widespread in the golden dove group to which the whistling dove belongs, it represents an unusual adaption within the pigeon family. This difference in the levels of parental care was suggested as an explanation of the sexual dimorphism in the golden doves.

保护状况

The whistling fruit dove is considered near threatened by the IUCN. The species is currently common in the forests of Kadavu and Ono, with an estimated population of 10,000 birds (BirdLife International 2006). However it has a restricted range and it is declining due to habitat loss.

Tawny-shouldered Blackbird

Tawny-shouldered Blackbird

Agelaius humeralis

A gregarious species that uses a wide variety of habitats. It is colored black overall except for a yellow-orange shoulder patch, which is usually visible when perched, but should always be apparent in flight. The very similar male Red-shouldered Blackbird can be told by its redder shoulder. The female Red-shouldered Blackbird lacks color on the shoulder and thus can look nearly identical to a Tawny-shouldered Blackbird when its shoulder patch is hidden; sometimes, identification of females can only be made in flight. The Shiny Cowbird lacks a shoulder patch, is quite glossy, and has a shorter and stouter bill than the Tawny-shouldered Blackbird. Vocalizations include a rough “chet,” a sharp musical “chee,” and a metallic upslurred “willeee.”

Henicophaps albifrons

A large, distinctive pigeon of lowland and montane forest. Long bill, white forehead and dark reddish neck. Metallic bronze, green and blue bands in the wing. Feeds on the forest floor and perches upright on a branch, bobbing its head. Shy and difficult to see. Thick-billed Ground-Pigeon is a similar size but has a white cheek rather than forehead and lacks iridescence in the wing. Voice, a repeated series of rapid, upslurred “woop” notes.

Northern Crombec

Northern Crombec

Sylvietta brachyura

A small and virtually tailless warbler with a gray-brown back and rufous underparts. There is some geographical variation; the throat can be dull rufous, dull white, or bright white. Always shows a gray-brown eye-line. Found in a wide variety of savanna and woodland habitats. Similar to Red-faced Crombec, but has a strong eye-line, and in the area of overlap, usually shows a bright white throat. The song is a quick, jumbled whistled phrase that varies somewhat across the range. The call is a rapid wooden trill.
