Dideric Cuckoo
Chrysococcyx caprius
A small, greenish cuckoo. The male has barred flanks, white flecking on the wing, white patches in front of and behind the eye, and a distinctly red eye surrounded by a red eye-ring. The bronzy-green female has a diagnostic white patch in front of the eye, a plain back, and white patches in the wings. This common resident and migrant is not a habitat specialist, but it prefers riverine and wetland areas where its preferred brood-parasite hosts, weavers and bishops, are common. The distinctive call is a loud, rising, high-pitched “deee-deee-deee-deee-dederik”.
识别特征
The diederik cuckoo is a smallish cuckoo at 18 to 20 cm. Adult males are glossy green above with copper-sheened areas on the back and whitish underparts. They have a broken white eye-stripe and a short, green malar stripe. All remiges have three to four white spots on the inner vanes. The four green outer tail feathers are tipped white, and the outermost pair are spotted white on both vanes.<p>Females show more copper above, and have coppery barring on the flanks. The underparts are often washed brownish.<p>Juveniles have a red bill, streaky throat and a white wing-bar. They are more copper-coloured above and browner below than the females, and the flank markings are brown blotches.
分类信息
The diederik cuckoo was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux from a specimen collected in the Cape of Good Hope region of South Africa. 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 Cuculus caprius in his catalogue of the Planches Enluminées. The diederik cuckoo is now placed in the genus Chrysococcyx that was erected by the German zoologist Friedrich Boie in 1826. The species is monotypic.<p>The generic name Chrysococcyx combines the Ancient Greek khrusos meaning "gold" and kokkux meaning "cuckoo". The specific epithet caprius is from the Latin cupreus meaning "coppery". The common name "diederik" is from Afrikaans "diedrik", an onomatopoeic rendition of the bird's call.

行为
The diederik cuckoo is a brood parasite. It lays a single egg mostly in the nests of weavers, especially the village weaver and the bishops in the genus Euplectes. For example, it has been recorded in red-collared widowbirds.<p>The diederik cuckoo takes a variety of insects and insect larvae. It is a noisy species, with the persistent and loud deed-deed-deed-deed-er-ick call from which it gets its name. Usually four clear, roughly identical, notes followed by a little twitter.

Black-billed Thrush
Turdus ignobilis
A drab thrush, common in open habitats and woodlands in the lowlands but also wanders up into Andean foothills. Nondescript grayish-brown with a pale whitish belly. Note indistinct streaking on throat; some populations also show a white patch on chest. Sexes similar. Usually seen singly or in pairs. Conspicuous. Song is a typical thrushlike series of musical phrases.
Buff-breasted Sandpiper
Calidris subruficollis
Elegant buffy sandpiper; peaceful-looking with large eye and plain face. Relatively short bill and medium-length yellow legs. Adults and juveniles similar, but juveniles show crisp scaly back pattern. Similar to Baird's Sandpiper but longer yellow legs and more evenly buffy coloration extending onto the belly. Smaller than Upland Sandpiper and lacks extensive dark markings on face, neck, and sides. Breeds on Arctic tundra. During migration, found in dry habitats such as plowed fields, sod farms, and higher areas of beaches. Winters in South America.
Southern Carmine Bee-eater
Merops nubicoides
A large, spectacular, slender, carmine-pink-and-teal-blue bee-eater with a long pointed tail, black bill, and black facial mask. The immature is duller and shorter-tailed. It gathers in large groups that often attend bush fires, and it specializes in catching large flying insects, including dragonflies, butterflies, and locusts. Breeds colonially by burrowing into sandbanks. It has a complex three-stage migration; it generally breeds between 13–20°S from August–September, disperses south of the breeding area December–March, and then moves north of the breeding area April–August. “Trik-trik-trik” calls are more guttural than those of European Bee-eater. Similar Northern Carmine Bee-eater has a teal-colored (not carmine) chin and throat.
