Gray Go-away-bird
Crinifer concolor
Unusual gray turaco with a long tail and towering crest. The flight is hesitant, and the tail flops up and down. Usually in small groups, which often perch up conspicuously on trees and bushes. The calls include a series of grumpy yelps, and the classic nasal “go-waaay” call. Similar in shape to other go-away-birds, but there is little overlap in range, and easily separated by the uniformly gray coloration.
Identification
The sexes are similar. They measure 47–51 cm from bill tip to tail tip, and weigh some 200 to 300 g. They have an almost uniform smoky-grey plumage with long tails and (similar to mousebirds) a wispy, back-swept crest of some 6 to 7 cm in length. The crest can be raised almost vertically when excited. The strong, decurved beak is black and the gape and tongue strikingly pink. The plumage is darkest grey on the chin and throat, and palest around the eyes and on the belly. The breast plumage is washed slightly olive like that of its near relative, the bare-faced go-away-bird.
Taxonomy
The grey go-away-bird was formally described in 1833 by the Scottish zoologist Andrew Smith from specimens collected inland from Port Natal (now Durban) in South Africa. He coined the binomial name Corythaix concolor. The specific epithet concolor is Latin meaning "uniform", "similar in colour" or "plain". The grey go-away-bird is now placed in the genus Crinifer that was introduced by the Polish zoologist Feliks Paweł Jarocki in 1821.<p>Four subspecies are recognised:

Range and habitat
It is native to southern Angola, southern DRC, Zambia, southern Tanzania, Malawi, Mozambique, Namibia, Botswana, Zimbabwe, South Africa and Eswatini. It occupies any arid to moist, and relatively open savanna woodlands, especially where Acacia trees are present. They frequent the edges of miombo woodland, and occur commonly along water courses, dry riparian forest and in Acacia woodland on alluvium. It also occurs commonly on farms and in suburban gardens and parks. They require water, and disperse along tributaries of desert rivers when water flows. It is absent from areas that lack suitable fruiting trees, and seems to desert areas where woody plant encroachment occurs. They have no regular migrations, but wander about irregularly in search of food and water.

Behavior
Though their flight is rather slow and laboured, they can cover long distances. Once in the open tree tops however, they can display the agility which is associated with the Musophagidae, as they run along tree limbs and jump from branch to branch. They can form groups and parties numbering even 20 to 30 that move about in search of fruit and insects near the tree tops.<p>Its diet is mainly fruit (such as wild figs and berries), flowers, buds, leaves, termites, and snails. Fruit are obtained from plants in the genera Ficus, Viscum, Loranthus, Diospyros, Lannea, Ziziphus, Salvadora and Flueggea, among others. They also feed on fruit of exotic invasives like seringa, and disperse their seeds.<p>The flimsy nest platform is built from fairly thin, and often thorny sticks. It has the appearance of a substantial dove's nest, and their almost round, white eggs can be seen from below. Usually three eggs are laid in a nest that is placed at the center of an isolated tree. The adults share all parental duties, and the chicks start clambering about before they are able to fly. The chicks are covered in dense brownish down, and are fed regurgitated food by the parents. The breeding season is July to August in Angola, April to November in Malawi, August to September in Zambia, Sept and December to April in Namibia, and all months in Zimbabwe and South Africa.

Other Birds
Black-chinned Sparrow
Spizella atrogularis
Long-tailed, pale gray sparrow with contrasting brown back and small pink bill. Face of breeding male looks like it's covered in soot. Reminiscent of Dark-eyed Junco but juncos show prominent white in tail; also note Black-chinned Sparrow's streaked back and brown edges on wing feathers. Prefers shrubby hillsides and slopes with large bushes and rocky outcroppings, from the southwestern U.S. to central Mexico. Song is often likened to a dropped ping-pong ball: an accelerating series of notes, not as clear-toned as Field Sparrow.
Rufous-faced Crake
Rufirallus xenopterus
Very secretive crake with a relatively long tail and a stout bill. Note the rufous neck and crown that contrast with a black back, the thinly barred black-and-white sides, and the white belly. Inhabits shallow flooded marshes with tussocky or matted grasses. Compare with Red-and-White Crake, which lacks barred wings and has a white (not black) vent, a yellowish (not gray) bill, and gray (not red) legs. Song is a long descending trill.
Shy Heathwren
Hylacola cauta
Small bird of open mallee and heathland in southwestern Australia and southern South Australia. Medium gray-brown above, whitish below, with distinct pale supercilium, red-brown rump, large white spot in the primaries (surrounded by black), dark chest streaking, and long, cocked tail. Forages quietly on the ground. Compare Chestnut-rumped Heathwren, which has a smaller pale wing spot, no black in wing, and paler legs. Despite the name, this species is not particularly shy.
