Dry savanna woodland and arid scrubland.
Includes seeds and insects, also nectar from Leonotis nepetifolia; birds will bite flowers off at base to steal nectar.
They are polygynous nesting in small colonies in trees. The male builds an onion shaped nest from woven green grass. Clutch of 2-4 variable blue-white, pink-white or greenish, white eggs sometimes with fine black spotting, others with red or violet flecks.
Song is a dry sputtering squeaky trill, interspersed with rasps, whistles and chirps.
Nomadic flocks form in non-breeding season. Movements likely, influenced by food supply.
