Identificación

The striped kingfisher of the nominate subspecies H. c. chelicuti averages 16 to 18 cm (about 6.5 in) from beak to tail. Perched adults look mostly greyish brown on the upper part of the body. The lower back, secondary flight feathers, and tail are metallic blue; this colour is much more visible when the bird flies than when it is perched, as is a white patch at the base of the primary flight feathers. The wing linings are white with a black border, and in males a black bar at the base of the primaries. The underparts are off-white, buffier on the breast, with brown streaks on the sides in Kenyan birds and also on the breast in southern African birds. Also streaked dark brown is the top of the head, with the background buffy grey in males and brownish in females. The sides of the head, throat, and a collar around the back of the neck continue the off-white of the underparts. A black line goes around the back of the neck, above the white collar, and through the eyes. The bill is blackish above and at the tip, otherwise reddish-orange below.<p>The juvenile resembles the adult but is paler. It has less blue on the wings, a darker crown, dusky tips to the breast feathers, and dull red on the lower mandible.<p>The call is distinctive, "a high-pitched, piercing 'cheer-cherrrrrr'" or a far-carrying "KEW, kerrrrrrrrr" in which the rs represent a repeated descending trill lower in pitch than the first note. It is often given at dusk in a display where the bird opens its wings.<p>The northern subspecies H. c. eremogiton has a grey-brown crown and mantle and almost unstreaked underparts.

Distribución y hábitat

This species occurs in Sub-Saharan Africa except in dense forests (especially near the Congo River), the Horn of Africa, the Namib Desert and South Africa. It prefers woodland, thorn scrub (thornveld), dry bush, and open savanna, but avoids intensively farmed land.<p>There are two subspecies: H. c. chelicuti in most of the range, and H. c. eremogiton (Hartert, 1921) in the northern desert parts of the range from central Mali to the White Nile region of eastern Sudan. They hybridize in southern Mali.
