Bar-bellied Cuckooshrike
Coracina striata
Sleek but sturdy gray bird with fierce yellow eyes. Across much of range, males are gray overall, and females have black-barred rump and underparts. Birds on the West Sumatran islands lack barring in both males and females, while birds on the Kangean Islands (off northeastern Java) have males with barred undertails and females with unmarked pale undertails. Occurs widely in lowland and foothill forest and forest edge, foraging at middle and upper levels, often with other species. Frequently gives loud scratchy screeches, often in pairs or a descending series.
识别特征
The bar-bellied cuckooshrike is 24–32 centimetres (9.4–12.6 in) long. The plumage and size are variable. In the Philippines, the subspecies guillemardi and mindorensis are uniformly grey, with some black on the male's head; in striata, cebuensis, and difficilis, the male has faint barring on the rump, and the female's belly is barred black and white; in panayensis, the male also has black and white bars on the belly, and the female has additional barred patches on the breast; in kochii, the male's breast is also barred, and the female's underparts are entirely barred. In C. s. sumatrensis of the Thai-Malay Peninsula, Sumatra and Borneo, the male has grey upperparts with some barring on the rump and lower-tail coverts, and the female's underparts are barred up to the lower breast. The juvenile bird has grey upperparts and entirely barred underparts in panayensis and kochii; in sumatrensis, the juvenile has brown, white, and black upperparts, and the underparts are white with black bars.

The bar-bellied cuckooshrike was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1775 in his Histoire Naturelle des Oiseaux. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Corvus striatus in his catalogue of the Planches Enluminées. Buffon believed that his specimen had come from New Guinea but the species does not occur there; the type locality has been designated as the island of Luzon in the Philippines. The bar-bellied cuckooshrike is now placed in the genus Coracina that was introduced by the French ornithologist Louis Pierre Vieillot in 1816. The generic name Coracina is from the Ancient Greek korakinos meaning "little raven", a diminutive of korax meaning "raven". The specific epithet striata is from the Latin striatus meaning "striated".<p>It was variously placed in the genera Graucalus and Artamides until Coracina was widely accepted around the early 1940s. The IOC World Bird List recognises fourteen extant subspecies: Coracina striata sumatrensis, C. s. simalurensis, C. s. babiensis, C. s. kannegieteri, C. s. enganensis, C. s. bungurensis, C. s. vordemani, C. s. difficilis, C. s. striata, C. s. mindorensis, C. s. panayensis, C. s. boholensis, C. s. kochii and C. s. guillemardi. C. s. cebuensis, formerly found on Cebu, is extinct. The Andaman cuckooshrike (Coracina dobsoni) is sometimes considered a subspecies. The Handbook of the Birds of the World considers panayensis to be a separate species.

分布与栖息地
This cuckooshrike is found in the Thai-Malay Peninsula, Sumatra, Borneo, the Philippines, and many small islands in the area, such as the Kangean Islands and Natuna Islands. It became locally extinct in Singapore around the late 1960s. It lives at low elevations, its habitats being back-mangrove forest, dry forest, freshwater swamp forest, secondary forest, and sometimes scrubs and plantations.

Island Canary
Serinus canaria
Restricted to the Azores, Canary Islands, and Madeira. Slightly bigger than European Serin and yellow-green overall with a pale bill, and a dark forked tail. Has a streaky rump, but this can be hard to see. Males are greenish-yellow below while females are duller and grayer on the breast and neck. The song is very melodic and rich. Found in forests, plantations, gardens, and orchards, sometimes gathering in flocks. Introduced to the Midway Atoll, where coloration ranges from unstreaked bright yellow to almost white.
Brown Emutail
Bradypterus brunneus
Medium-sized, rich-brown bird with a weird spiky tail. Scarce and incredibly shy bird that is unlikely to be seen unless you’re expressly searching for it. Madagascar endemic that is found in eastern rainforest at middle and high elevations. Skulks in the understory, with a strong preference for dwarf bamboo. Loud song is a couple of short “swee” notes followed by a long, dry rattle. Far less likely to be seen than the common Madagascar Brush-Warbler. In case of any confusion, look for the Brown Emutail’s warmer brown coloration and wispy tail.
Painted Stork
Mycteria leucocephala
A large stork with a long yellow bill that curves down at the tip, like that of an Ibis. Adult is primarily white with black striped markings on the wings and bright pink on tertials. Also note the bright orange face, pinkish legs, and speckled band across the chest. Immatures are duller, with a brown wash, and lack the chest band. These storks typically fly with their head and neck drooping almost at or below the belly level. Often seen near water bodies such as wetlands, marshes, and flooded agricultural fields. Breeds in crowded colonies, often with other waterbirds.
