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”.
Identification
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.
Taxonomy
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.

Calayan Rail
Gallirallus calayanensis
A large rail of forest floor on Calayan Island. Overall slaty-gray in color, slightly browner on the back, with a blackish face, long orange-red legs, and a fairly long, stout orange-red bill. Forages on the forest floor for snails, beetles, and millipedes. Similarly sized birds on Calayan include Barred Rail and Plain Bush-hen, but both avoid forest interior. Tabon Scrubfowl is found in forest, but lacks the orange bill and legs. Voice is a nasal squawk.
White-necked Rockfowl
Picathartes gymnocephalus
A bizarre and unique ground-loving bird, large but slender, with long legs, tail, and neck and extensive yellow facial skin with large dark brown patches behind the eyes resembling earmuffs. Resident in lowland forest, hill forest, and secondary scrub where there are large boulders and caves inside the forest for them to use for nesting and roosting. Forages in pairs or groups on the forest floor, bouncing effortlessly through the undergrowth on strong legs and returning to rocks most nights to roost communally. Mostly silent, but makes low clucking and other soft contact calls.
Levant Sparrowhawk
Tachyspiza brevipes
Small, dark-eyed hawk of woodland, scrub, riparian corridors, and wooded plains and slopes. Note the adult's grayish upperparts and orange-barred underparts; females are larger and darker than males, with a dark central throat stripe. When in flight, note contrast between pale underwings and dark wingtips. Juveniles are brown above and striped below. Compared to the slightly larger Eurasian Sparrowhawk, Levant is neater-looking and more falcon-like, with more pointed wings. Also compare with very similar Shikra and various African sparrowhawks in its wintering range. Strongly migratory; often migrates in huge, tight flocks. Feeds on birds, which it catches in rapid low flight.
