Chestnut-backed
Button-quail
FAMILY: Phasianidae
GENUS: Turnix
SPECIES: castanota
OTHER NAMES:None.
Description:
The name Chestnut-backed
Button-quail is perhaps not entirely appropriate for this bird as it is less
colourful and more uniformly cinnamon in colour than its close relatives the
Buff-breasted and Painted Button-quails. Not strongly nomadic, the Chestnut-backed
Button-quail tends to move locally in search of food supplies. Outside the
breeding season this bird is often encountered in small parties of 5 to 20
individuals.
As is the case for other button-quail the female is considerably larger than
the male. She is however, less distinctly coloured and patterned. Males have a
pair of dark lines separated by a white line running along the length of the
crown. The remainder of the upper surface (to the rump which is plain) is
cinamon brown with each feather bearing a black mark, white spots and cream
edging. The wings are a pale grey which gives way to cinnamon on the inner
flicht feathers and shoulders. Wing coverts are finely spotted with white. The
throat is white, tending to grey on the breast and flanks with coarse cream
spots at the centre of each feather. The eye is bright yellow, the bill a
creamy-grey and the legs and feet yellow.
Females resemble males, but are generally duller. The crown lacks the dark
lines and the remaining upper parts are a plain cinnamon0brown with fine white
speckling on the mantle. The eye is orange.
Immatures resemble males but are more clearly marked and more coarsely spotted
overall. The eye is a cream colour. Downy young are brown-rufous above with
central and lateral cream stripes. The underparts are a pale cream.

Female 180mm

leaves.
