The weebill (Smicrornis brevirostris) is a species of bird in the family Acanthizidae. It is an insectivorous passerine that is found throughout mainland Australia. At 8 to 9 cm (3.1 to 3.5 in) long, it is Australia's smallest bird. It was originally described by John Gould in 1838, and four subspecies are recognised. The weebill's plumage is nondescript, with olive-grey upperparts and paler, more yellowish underparts. It grades from more brownish plumage in the southern regions of Australia to more yellow in tropical areas. Wikipedia →
