Cuban Trogon
Priotelus temnurus
A splendid medium-sized inhabitant of woodlands; often found in pairs. Its iridescent blue-green back, smooth gray chest, and brilliant red belly easily distinguish it from all other species in range. Usually sits motionless near the middle level of the forest, but when feeding (typically on flowers and fruit) hovers conspicuously. Often found by its loud calls, which are somewhat varied. One common call is a “cu-cu-cu-cu-cu-cu,” often accelerating; another is a resonant quavering “cu-u-low,” given several times in succession.
识别特征
The Cuban trogon is 23 to 28 cm (9.1 to 11 in) long and weighs 47 to 75 g (1.7 to 2.6 oz). Its plumage colors match those of Cuba's flag, and are the same for both sexes. The two subspecies also differ only slightly. Their beak is reddish pink with a dark culmen. Adults have a blackish face with reddish eyes, a dark metallic blue crown and nape, and a metallic green back and rump. Their cheeks, chin, and throat are white becoming clear gray on the breast and upper belly. Their lower belly and undertail coverts are red. Their tail is graduated, with the innermost feathers forming a point. The three innermost pairs of tail feathers are glossy blue-black with some bronzy highlights. The three outer pairs have blue-black bases and are mostly white beyond. The flight feathers and wing coverts are generally dark metallic green to black with a complex pattern of white spots. Juveniles have similar plumage to adults but generally are duller, with buffy gray underparts and reddish pink undertail coverts.
分类信息
The Cuban trogon shares its genus with the Hispaniolan trogon (P. roseigaster). It has two subspecies, the nominate P. t. temnurus and P. t. vescus.<p>In English the bird is commonly known as the Cuban trogon, while in Spanish, it is referred to as the tocororo. This local name is onomatopoeic, and was derived from its repeated call, "toco-toco-tocoro-tocoro". It is the national bird of Cuba.

分布与栖息地
The nominate subspecies of the Cuban trogon is found throughout the main island of Cuba and on several large cays off the Camagüey Province shore. P. t. vescus is found only on Isla de la Juventud (Isle of Pines). The species inhabits both primary and secondary forest and also shrublands and smaller woodlands near watercourses. It favors humid shady areas within those landscapes and occurs at all elevations but is most common at higher ones.

行为
The Cuban trogan is mostly sedentary but makes seasonal local movements in elevation or in response to the availability of food. Their flight style is rather choppy and noisy.<p>The Cuban trogon is usually found in pairs though sometimes in groups of three or four. They seem "indifferent to human presence in the immediate vicinity."<p>The Cuban trogon usually forages at the middle level of the forest; it takes food by sallying from a perch or by hovering at foliage or fruit. Its diet is mostly insects, fruit, and buds but it also feeds small lizards to young.<p>The Cuban trogon's breeding season is mostly April to July. It nests in natural cavities or abandoned woodpecker holes, usually in trees but sometimes in arboreal termitaria. The clutch size is three or four eggs. The incubation period is about 18 days and fledging occurs about 21 days after hatch <p>The Cuban trogon's song is "a pleasant toco-toco-tocoro-tocoro..., repeated for long periods at frequent intervals." It also gives "a steady, rapid series of staccato notes" and "a low and short mournful call that makes it difficult to locate."

Pink Cockatoo
Cacatua leadbeateri
Distinctive cockatoo found in a wide variety of habitats across inland Australia, typically favoring dry woodlands, where it feeds on seeds. Relatively small, with pink underparts and white upperparts. Magnificent, long white crest has colorful band of red at base, in subspecies leadbeateri inset with another band of yellow. In flight, pink underwings evident. Often observed feeding on the ground beside roads. Call a wavering, high-pitched note.
White-capped Albatross
Thalassarche cauta
A medium-sized dark-backed albatross with pale underwings outlined by a narrow dark border and a dark notch in the armpit. The adult has a whitish head with grayish cheeks that give it a “white-capped” appearance. The gray-green bill has a yellowish tip to both mandibles. Juveniles are grayer on the head with gray bills. The species breeds on islands off Tasmania and New Zealand but disperses widely across the southern Oceans between 15 and 60°S, where it is a frequently encountered pelagic seabird. Similar albatrosses have a dark-tipped (not pale-tipped) lower half to the bill, and Salvin’s Albatross has a pale gray head and Chatham Albatross a slaty-gray head, further differentiating them from White-capped Albatross. Juveniles of these three are very difficult to separate.
Erckel's Spurfowl
Pternistis erckelii
A pheasant-sized game bird with a chestnut crown, white throat, and white streaks above and below. Males are larger than females. Occurs in grasslands, shrubby areas, and gullies, usually in uplands. Prefers wetter areas than Gray and Black Francolins. Call is a loud series of laughing “er-er-er” notes descending in pitch toward the end. Introduced to Hawaii where it is common on Kauai, Lanai, and Hawaii and local on Oahu and Maui.
