Remarkably tiny bird with very short, stubby bill. Upperparts gray-brown, underparts variably cream and yellow, with pale eyebrow and pale eye. Inhabits dry, open woodlands, especially eucalypt forests. Very vocal as it forages in trees, where it feeds primarily on insects, sometimes in mixed flocks with thornbills and pardalotes. Distinctive loud song, given year-round, often rendered “I’m a wee-bill!”
