Cuban Pygmy-Owl
Glaucidium siju
A very small, tame owl of wooded habitats that is active both day and night. Depending on attitude, its staring yellow eyes and prominent arched white eyebrows can impart cuteness or ferocity. Often found perched with tail cocked, and when flushed, typically flies only a short distance on rounded wings. Occurs in two color types, gray and rust. Song is a low whistled “whuh” or “hoo” given in a slow series. Other vocalizations include a high, thin whistled “tsee, tsee-tsee-tsee-tsee-tsee” that grows progressively louder, and a series of high squeaks. No similar species within its range.
识别特征
The Cuban pygmy owl is 16 to 17 cm (6.3 to 6.7 in) long. Males weigh 47 to 68 g (1.7 to 2.4 oz) and females 66 to 102 g (2.3 to 3.6 oz). It has two color morphs, gray-brown and rufous; the former is more common. Both morphs have a pale grayish face, whitish to cinnamon "brows" over yellow eyes, and a pair of dark "false eyes" on the nape. The nominate gray-brown morph's crown, sides of the head, and back are grayish brown with white spots; the shoulders have diffuse dark barring. The tail is also grayish brown, with white bars. The throat is brown, the sides of the breast and flanks brown with darker bars, the center of the breast white, and the rest of the underparts off-white with dark brown streaks and spots. The rufous morph replaces the gray-brown with cinnamon. G. s. turquinense is much darker and has fewer spots on the upperparts. G. s. vittatum is larger than the nominate and the barring on the shoulders is more defined.

分布与栖息地
The Cuban pygmy owl is the most common and most frequently observed owl in the country. The nominate subspecies is found throughout the main island of Cuba except on its highest mountain, Pico Turquino. Subspecies G. s. turquinense is found only on that mountain and G. s. vittatum on the Isla de la Juventud (Isle of Pines) and possibly the Guanahacabibes Peninsula. The species inhabits the interiors and edges of coastal, deciduous, and montane forest, both primary and secondary. It is also found in areas such as pastures with scattered trees, cultivated fields, plantations, and large city parks. In elevation it ranges from sea level to 1,500 m (4,900 ft).

行为
The Cuban pygmy owl is active in both daytime and the night. It hunts from a perch; though its diet has not been studied in detail, it appears to feed mostly on insects and small reptiles, and also takes small mammals, birds, and frogs.<p>The Cuban pygmy owl nests in the dry season of November to April. It lays a clutch of three or four eggs in a tree cavity, either natural or one previously used by a woodpecker. The female incubates the eggs.<p>The Cuban pygmy owl has two known vocalizations. The male sings "a series of more or less equally spaced notes similar to the song of the mountain pygmy owl (Glaucidium gnoma)". Both sexes make an apparent alarm call, "a rapid and accelerating series of rather higher-pitched, squeaky-sounding notes".

Great Reed Warbler
Acrocephalus arundinaceus
A hulking warbler that resembles Eurasian Reed-Warbler in coloration but far larger with a proportionately more massive head, heavy bill with a dark tip, and a broad, pale eyebrow. Breeds in reed beds, crashing through the reeds in short flights and bending stems when perched. Non-breeding habitat includes wet marshy areas, as well as drier habitats such as agricultural fields, savanna, and low scrubby growth. Song short but very loud and memorable with repeated phrases of "karra-karra-karra gurk gurk gurk chirrr-chirrr karra karra." Call a high-pitched “krrrrr."
Orange-banded Thrush
Geokichla peronii
An unmistakable thrush with a “tiger-striped” face pattern, a white throat, a broad orange chest band, orange flanks, a white belly, and extensive bold white wing markings. Juveniles show rusty wing spots, pale streaking, a black and buff breast band, and black flank spots. Forages singly or in pairs on the ground and in trees, in forests and wooded patches within lowlands and hills. Confined to the eastern Lesser Sundas. Gives a rich, musical song characteristic of thrushes, with sequences of fluty upslurred and downslurred whistled notes comprising repeated phrases mixed with softer, chuckling sounds and thin, high-pitched notes.
Indochinese Cuckooshrike
Lalage polioptera
Plain gray cuckooshrike with relatively little contrast overall. Male is gray with darker wingtips and a white vent. Female is paler gray with thinly barred underparts. Can be mistaken for Black-winged Cuckooshrike, of which both resident and migratory subspecies are within the range of Indochinese. Note Black-winged’s darker overall plumage, much fainter barring on the female’s underside, and more evenly spaced white spots on the black undertail (Indochinese’s white spots are all clustered together into a cohesive white blob). Inhabits open forests, particularly dry deciduous forests, as well as forest edges and gardens. Gives squeaky yelps, often heard when flying over in small flocks. Gives a descending series of high-pitched whistles.
