Racket-tailed Treepie

Crypsirina temia

Glossy black corvid with a long, broad-tipped tail and brilliant blue eyes. Plumage shines glossy blue-green in good lighting. Small black mask encloses the eye and bill base. Compare Ratchet-tailed Treepie, which is darker-eyed and has a tail shaped like a chainsaw. Clambers and jumps through the vegetation, singly or in pairs or occasionally small flocks, in open lowland and foothill forests and forest edges. Gives various rasping, croaking, and nasal notes.

识别特征

The racket-tailed treepie (Crypsirina temia) is an Asian treepie, a member of the crow family, Corvidae. It has a velvety-black forehead of short, plush black feathers with the rest of the bird being an oily green colour, though appearing black in dim light. The tail feathers which in this species are long and broaden at the tail's end are black also with a greenish tinge, as are the wings. The iris of the bird is a turquoise-blue darkening towards the pupil to a very deep or near black. The bill, legs and feet are black. This bird occurs in southern Burma (Myanmar), Thailand, Indo-China, Sumatra, Java and Bali in scrub and secondary growth, open fields and gardens, bamboo thickets and open forest often near villages. It almost always feeds in trees (arboreal) never feeding from the ground though coming down to bathe on occasion. It moves through the trees with great agility and uses its remarkable tail as a balancing organ. It eats mainly insects and fruit. A cup shaped nest is built in bamboo or shrubs especially thorny ones often surrounded by open grassy areas and normally lays 2–4 eggs. The voice is usually described as harsh and unattractive. It has several described calls but a whining call is often heard.

Mountain Trogon

Mountain Trogon

Trogon mexicanus

Fairly large trogon of pine and pine-oak forests in highlands; usually at upper levels in trees and often rather shy. Male is striking, with big, bold white squares on underside of tail. Female has broken white eyering on brown head and coarse black-and-white pattern under the tail. Elegant Trogon overlaps in range and can be told from Mountain by the coppery color on the top of the tail (male) or by the white stripe behind the eye (female). Also note the finely patterned tail on both male and female Elegant Trogons. The similar but smaller Collared Trogon is found mainly at lower elevation and has much finer barring on the underside of the tail.

Reunion Bulbul

Reunion Bulbul

Hypsipetes borbonicus

A medium-sized dark gray bird with a white eye, a black cap, and a carrot-colored bill. Endemic to the island of Reunion. Found in humid forest as well as secondary forest and forest dominated by exotic trees; now mostly confined to middle and high elevations. Often in small, noisy groups. Somewhat similar to male Reunion Cuckooshrike, but easily separated by the orange bill and pale eye. The song is an unmusical but varied series of rattling, metallic, and scraping notes, often given from a high perch. The calls include a “chek” note and a long mew. 

Mayotte Sunbird

Mayotte Sunbird

Cinnyris coquerellii

A small sunbird with a relatively short, slightly downcurved bill. Males are a beautiful mix of green, purple, red, and yellow. Females are fairly drab, with a dark-streaked pale breast and a yellow belly. Found in all habitats on the island of Mayotte, though most common in scrubby habitat rather than in forest. In its small range, it is the only sunbird, so it is easily identified by its bill shape. The song is a typical sunbird jumble of high-pitched notes, and the call is a rising whine.
