Wompoo Fruit-Dove
Ptilinopus magnificus

识别特征
This dove measures up to 45 cm (18 in), but are generally far smaller in northern regions. It has purple plumage around its neck, chest and upper belly. Its lower belly is yellow and it has green underparts. The sexes are similar and the juveniles have a duller and greener plumage compared to adults. Notwithstanding their bright plumage, they are hard to see amongst the forest canopy, thanks to their unobtrusive, quiet habits. Their call sounds like wollack-wa-hoo and often sounds very human.
分类信息
The wompoo fruit dove was formally described in 1821 by the Dutch zoologist Coenraad Jacob Temminck from a specimen that had been collected on the east coast of Australia. He placed it with the doves and pigeons in the genus Columba and coined the binomial name Columba magnifica. The wompoo fruit dove is now one of 57 fruit doves placed in the genus Ptilinopus that was introduced in 1825 by the English naturalist William John Swainson. <p>Five subspecies are recognised:

行为
The wompoo fruit dove can be seen in large flocks where food is abundant. The birds feed off fruit-bearing trees in rainforests such as figs. They also occasionally eat insects. They can eat large fruits whole and are able to acrobatically collect fruit of trees and vines. They do not like to travel long distances, preferring to stay in their local area and make use of whatever fruit are in season. The diet of this species was extensively studied in the Port Moresby area by Frith et al. (1976). Despite their small size, they are able to swallow fruits of 5 cm3 (0.31 cu in) volume, which would translate into a diameter of about 2 cm (0.79 in) in spherical fruit.<p>Major food items included:<p>Food items of minor importance were fruit of:<p>Breeding times will vary according to weather conditions. The nest is sturdily constructed from forked twigs not high from the ground. Both sexes help in the construction of the nest. One white egg is laid and the parents share the incubation and care of the chick. In the event that the chick dies, the doves will attempt to have a second offspring in the same season.<p>
保护状况
Widespread and common throughout its large range, the wompoo fruit dove is evaluated as Least Concern on the IUCN Red List of Threatened Species.

White-chinned Woodcreeper
Dendrocincla merula
Widespread but generally rare across much of northern South America. A medium-sized, plain brown woodcreeper with a bluish eye and limited white throat (sometimes nearly lacking). Completely unstreaked, so unlikely to be confused with anything but Plain-brown Woodcreeper, which has a stronger face pattern (especially a dark mustache) and lacks the bluish eye of White-chinned. Almost always seen near swarms of army ants, singly or in pairs. Occurs in lowland forest.
Rufous Spinetail
Synallaxis unirufa
Plain rufous bird with dark lores and long spiky tail. Sexes alike. Uncommon in the upper subtropics and temperate zone, mostly from 2,000–3,200 m. Could be confused with Rufous Wren but smaller and shier with spiky tail and plain unbarred wings. Pairs or small family groups are found low to the ground, often around patches of bamboo, where they can be tricky to see well. Listen for the single “pweep!” call.
Orange-spotted Bulbul
Pycnonotus bimaculatus
Attractive bulbul of foothill and montane forest edges and clearings. Endemic to Sumatra, Java, and Bali; introduced to Lombok. Brown above and white below, with bright orange patches on the face and a golden-yellowish tinge to the wings and cheeks. Also note the weak crest, which is not always raised. Generally unmistakable in its range; only confusion species is Aceh Bulbul, but note present species’ pale belly and range differences. Often gathers at fruiting trees. Call is a hard, decisive-sounding “tjik”, often given in series. Song is a bubbly series of bright fluid notes, often given with a somewhat hesitant quality.
