Red-necked Spurfowl
Pternistis afer
Large, chunky francolin with bare red skin on the throat and around the eye. There is much geographical variation in the presence or extent of white on the face, black-and-white streaking below, and black on the belly. Found in a wide range of habitats, including moist savanna, grassland, thickets, cultivation, and forest edge. The call is a series of rough “krek” notes, sometimes with a rollicking introduction. Bare red throat separates it from most other francolins. In areas of overlap with Swainson’s or Gray-breasted Francolins, Red-necked can be identified by black-and-white striped underparts.
识别特征
The red-necked spurfowl is 25–38 cm (9.8–15.0 in) in length, with significant size differences between the subspecies. It is a generally dark spurfowl, brown above and black-streaked grey or white underparts. The bill, bare facial skin, neck and legs are bright red.
分类信息
The red-necked spurfowl was described in 1776 by the German zoologist Philipp Ludwig Statius Müller and given the binomial name Tetrao afer. The type locality was later designated as Benguela in western Angola. The specific epithet afer is the Latin word for "African". The species is now placed in the genus Pternistis that was introduced by the German naturalist Johann Georg Wagler in 1832. A molecular phylogenetic study published in 2019 found that the red-necked spurfowl is sister to the grey-breasted spurfowl.<p>Although many subspecies have been described only four are now recognised:

The red-necked spurfowl is a wary species, keeping to deep cover, although it sometimes feeds in open scrub or cultivation if disturbance is limited and there are thickets nearby. The nest is a bare scrape, and three to nine eggs are laid.

Plain Prinia
Prinia inornata
A common prinia with drab gray-brown plumage that varies in tone across its range. Note the pale, wide eyebrow and the long tail that appears as if it is loosely attached to the body. Breeding birds have a black bill and a shorter tail. Common in various habitats, especially farms and wetlands, but avoids woodlands with a canopy. A somewhat bold species, it often skulks in the undergrowth but sings from exposed perches. The song is a repeated series of insectlike trills. Calls include various buzzing and clinking notes. Also produces snapping sounds with its wings.
Fuscous Flycatcher
Cnemotriccus fuscatus
Medium-sized flycatcher found in a variety of dense scrubby habitats often close to water. Note the pale wingbars and eyebrows that contrast with the gray-brown back and yellowish belly. Several distinctive subspecies differ in plumage tones, extent of the eyebrow, bill color, and call. Similar to Euler's Flycatcher, but with a strong eyebrow. The song is a sharp “jet-jet-pew-pew,” with more emphasis on the last note.
Cream-colored Courser
Cursorius cursor
Distinctive wader of desert areas, uniform sandy-brown with a blue back of head framed by a white and black stripe meeting at the nape. Bill is slightly down-curved. Very tall and slim with long legs that it uses to run across desert and semi-desert areas with its head held high. Dramatically patterned in flight with black flight feathers and underwings contrasting with its sandy body.
