Moluccan Eclectus
Eclectus roratus
Robust, big-headed, and rather short-tailed parrot endemic to the Moluccas, where it inhabits lowland and foothill forests. Male bright green with red underwings and orange bill, female bright red with violet belly and dark bill. Usually seen flying above forests at first light, squawking loudly. Calls include an ear-shattering, high-pitched squawk, as well as a lower, crow-like caw. Formerly grouped with other closely related species under “Eclectus Parrot.”
识别特征
The Moluccan eclectus is unusual in the parrot family for its marked visible light sexual dimorphism in the colours of the plumage. A stocky short-tailed parrot, it measures around 35 cm (14 in) in length. The male is mostly bright green with a yellow-tinge on the head. It has blue primaries, and red flanks and underwing coverts. Its tail is edged with a narrow band of creamy yellow and is dark grey edged with creamy yellow underneath, and the tail feathers are green centrally and bluer as they get towards the edges. The grand Eclectus female is mostly bright red with a darker hue on the back and wings. The mantle and underwing coverts darken to a more purple in colour, and the wing is edged with a mauve-blue. The tail is edged with yellowish-orange above and is more orange tipped with yellow underneath. The upper mandible of the adult male is orange at the base fading to a yellow towards the tip, and the lower mandible is black. The beak of the adult female is all black. Adults have yellow to orange irises and juveniles have dark brown to black irises. The upper mandible of both male and female juveniles are brown at the base fading to yellow towards the biting edges and the tip.The abdomen and nape of the females are blue in most subspecies, purple abdomen and nape in the subspecies (roratus) and lavender abdomen and nape in the (vosmaeri). Females of riedeli and vosmaeri also have yellow undertail coverts. The female vosmaeri displays the brightest red of all the subspecies, both on the head and body. They don't tend to talk in clear voices until they are 1 year old.<p>A blue colour mutation has appeared in avicultural eclectus populations as a result of a recessive gene. The cock bird is light blue, while the hen is a combination of dark blue, white and grey.
分类信息
Ornithologists usually classify the Moluccan eclectus as a member of tribe Psittaculini in the family Psittacidae of order Psittaciformes. However, some recent thoughts indicate a great deal of commonality between the eclectus parrots and the Lorini tribe.[verification needed][citation needed]<p>Sir D'Arcy Wentworth Thompson noted similarities in the skull were noted between the eclectus parrots and members of the genus Geoffroyus, specifically in the auditory meatus and the prefrontal reaching but not joining the squamosal bones. The skull of members the genus Tanygnathus is also generally similar.<p>Three subspecies of Moluccan eclectus are known, although the species as a whole needs reviewing. Access to some regions where the species occurs is difficult due to geographical or political reasons, hence field observations have been limited. Furthermore, many skins collected in the early part of the 19th century have deteriorated in some museums. However, most eclectus skins in US museums are in good condition. In captivity in the U.S., some of the most common subspecies are Vosmaer's, and the New Guinea red-sided.

Song Sparrow
Melospiza melodia
One of the most common and widespread sparrows in North America. Fairly large with a long, rounded tail. Overall coarsely patterned with gray and brown, usually with more reddish-brown wings and tail. Look especially for thick brown streaks on the underparts and a broad dark mustache stripe. Significant variation in plumage geographically: relatively pale and rusty in the southwestern U.S.; blacker streaking in California; overall dusky in the Pacific Northwest. Larger, longer-tailed and usually more rusty than Savannah Sparrow. Found in a variety of scrubby habitats both near and far from human development, especially edges of fields, often near water. Listen for husky "chimp" calls and melodic song with chips and trills.
Ornate Fruit-Dove
Ptilinopus ornatus
A fruit dove primarily of foothill forest but wanders to lowland and montane forest. Two very different races. Dark red-capped race from the Bird’s Head of New Guinea, and yellow-green capped further east. Note the white band from the bill around the back of the neck and clay-colored chest. Similar to Pink-spotted Dove, but Ornate Fruit-Dove has a dark red wedge on the shoulder and yellow tip to the tail. Voice a slow but accelerating series of rising “woop” notes, similar to that of Pink-spotted but not as fast.
Brown-chested Martin
Progne tapera
Large swallow with distinctive brown band across chest. Chest band is typically sharply demarcated, but can look diffuse with some spotting down the center of the belly. Otherwise brown above and pale below. Similar in plumage to Bank Swallow but larger and lankier. Found in the lowlands, usually in open areas near water, either singly or in loose flocks.
