Blue-naped Parrot
Tanygnathus lucionensis
Medium-sized parrot with a huge candy-red bill. Bright green overall, with eye-catching blue-and-yellow edgings on the wing feathers. Namesake sky-blue patch, which extends from the upper nape to the back of the crown, can be difficult to see. Inhabits lowland and foothill forests and other wooded areas, often on small offshore islands. Forages in flocks, screeching loudly to one another to stay in contact. Native to the Philippines and small offshore islands in Malaysia; feral population established in Kota Kinabalu. Declining across much of its range, and extirpated in some areas.
识别特征
This is a medium size parrot, around 31 cm (12 in) in length, primarily green except for a light blue rear crown and nape, pale blue lower back and rump, scalloped shoulders with orange-brown on black coverts, and blackish underwings with green underwing coverts.
分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the blue-naped parrot in his Ornithologie based on a specimen collected on the island of Luzon in the Philippines. He used the French name Le perroquet de l'Isle de Luçon and the Latin name Psittacus lucionensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. One of these was the blue-naped parrot. Linnaeus included a terse description, used the binomial name Psittacus lucionensis and cited Brisson's work. The specific name lucionensis is from Luzon in the Philippines. This species is now placed in the genus Tanygnathus which was introduced by the German naturalist Johann Wagler in 1832.<p>There are four subspecies:

分布与栖息地
The species is widespread throughout the Philippines, including the Talaud Islands and islands off north and east Borneo (with introduced population in Borneo itself, e.g. Kota Kinabalu). It is found in secondary forest, at forest edges and in plantations at elevations of up to 1000 m. Flock size is usually under a dozen. The blue-naped parrot feeds on mangoes, berries, seeds, nuts and grains. It nests in tree holes.

Chiriqui Quail-Dove
Zentrygon chiriquensis
Plump ground-dwelling dove, quite bright rufous overall compared with other quail-doves. Entire body is warm rufous, similar to Ruddy Quail-Dove, but note gray crown and black mustache line. Pinkish-red legs. Sexes alike. Prefers forests, usually on the ground unless flushed up into the lower levels of a tree. Like most quail-doves, often best seen by quietly walking along trails at dawn and dusk.
Vinaceous Rosefinch
Carpodacus vinaceus
Medium-sized finch of hilly and montane forests and dense brushy forest edge. Male is the color of red wine, with crisp lilac eyebrows. Female is dark buffy-brown with faint streaks on the back and breast. Forages on the ground near or in dense shrubs and bushes. Gives sharp bunting-like “zip” and “zink.”
Little Sparrowhawk
Tachyspiza minulla
A tiny, secretive and inconspicuous hawk that flies quickly and nimbly within woodland thickets and forest while hunting small birds, other vertebrates, and insects. It has a very distinctive white rump and two pale spots on the upper tail. Call is a distinctive high-pitched bisyllabic, down-and-upslurred “chy-lip”. Similarly-plumaged African Goshawk is much larger; Red-thighed Sparrowhawk is similar in size but prefers dense rainforest, is more rufous below, and generally lacks barring on the underside.
