A small bird found only in Tasmania and closely tied to forests containing white gum (Eucalyptus viminalis).
It has an olive-grey back, greyish-white underparts, yellow cheeks, and black wings tipped with large white spots. The yellow brightens in the breeding season. The bill is short and dark, and the legs and feet are fleshy brown.
It takes insects, lerps, and manna in the eucalypt canopy, catching them in the air or gleaning from leaves and branches. It nests in hollows and crevices in eucalypts.
It breeds from August to December and may lay two clutches of four or five white eggs per season. It nests in tree hollows or crevices, fallen limbs, fence posts, and occasionally holes in the ground. Both adults incubate for 16–20 days and feed the chicks; young fledge at about 25 days.
