Nubian Woodpecker
Campethera nubica
Mid-sized green-backed woodpecker with intricate patterning. The crown is red in males, red and white-speckled black in females. Note the heavily streaked ear, bold spotting below, and plain white throat. Generally common and conspicuous in most types of savanna habitat. Usually in pairs, which give a loud duet of “keek” notes. Very similar to Bennett’s Woodpecker, but separated by the black-streaked ear. Also similar to Golden-tailed and Mombasa Woodpeckers, but easily separated by the spotted rather than striped underparts.
识别特征
The Nubian woodpecker Is a medium-sized species growing to a length of about 21 cm (8.3 in). The male has a red crown and nape and a reddish streak on the cheek, while the female has a black crown speckled with white, a red nape, and a dark cheek stripe with white speckling. In other respects, the sexes are similar. The upper parts are olive-brown with much cream speckling and barring. The wings are greenish-brown barred with white and the tail greenish-yellow barred with brown, the shafts of the feathers being gold. The throat is cream and the head, neck, breast and belly are white, spotted and barred with black. The beak is grey with a dark tip, the eye red or pink, the orbital ring grey and the feet olive or grey. Various vocalisations are made, shrill ringing or piping notes repeated, often musical but sometimes metallic. Often sung in duet.
分类信息
The Nubian woodpecker 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 Nubia. 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 Picus nubicus in his catalogue of the Planches Enluminées. The Nubian woodpecker is now placed in the genus Campethera that was introduced by the English zoologist George Robert Gray in 1841. The generic name combines the Ancient Greek kampē meaning "caterpillar" and -thēras meaning "hunter".<p>Two subspecies are recognised:

Cardinal Quelea
Quelea cardinalis
The red head of the breeding male is distinctive. Non-breeding male and female are nondescript streaky brown birds with buffy eyebrows. Found in moist, grassy habitats, where it often appears after recent rain. Most records are of territorial breeding males. Becomes inconspicuous when not breeding, mixing with flocks of other weavers and seedeaters. The call is a rough “chyet” and the song is an accelerating series of annoyed-sounding notes. Breeding male very similar to breeding male Red-headed Quelea, but has less red on the nape and more on the breast, for a more cleanly “hooded” look.
Aldabra Drongo
Dicrurus aldabranus
Bold, black fork-tailed bird with a red eye. There is sometimes but not always a tuft of long feathers above the bill. Juveniles have an unusual pale-gray plumage, but still show the forked tail. Found in all habitats with bushes and trees on the remote Seychelles island of Aldabra, including forest, mangroves, and thick scrub. Perches prominently in the open, swooping out to catch insects on the wing. Often follows Madagascar Coucals and Aldabra Giant Tortoises, feeding on insects that they disturb. Song is a repeated sequence of whistles, creaks, and rasps.
Barred Puffbird
Nystalus radiatus
An unobtrusive bird with an oversized head and bill. Look for tiger-striped pattern—warm cinnamon-brown overall with uneven black barring. Also note slightly darker cap and staring pale eye. Uncommon; found around forest edge and secondary woodland in the lowlands from Panama to western Ecuador. Perches still for long periods of time, often on an exposed perch. Frequently detected by distinctive wolf-whistling calls.
