The weebill 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 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.

Australia
Typical Environment
Occurs across mainland Australia in a wide range of wooded habitats, including eucalypt forests, open woodlands, acacia scrub, riparian belts, and urban parks and gardens. It favors the outer foliage and canopy layers where it gleans insects from leaves and twigs. Generally avoids dense rainforest interiors and the most treeless deserts, but uses shelterbelts and scattered farm trees. Common in both coastal and inland areas, including modified landscapes. Often persists in fragmented habitats where mature trees remain.

Australia’s smallest bird, the weebill gets its name from its tiny, stubby bill. It forages high in tree canopies, often in mixed-species flocks, gleaning small insects and larvae. Pairs build neat, domed nests of plant fibers bound with spider silk and often dangling from foliage. Four subspecies are recognized across different Australian regions, with plumage grading from more brownish in the south to more yellow in the tropics.
Subspecies flavescens, Northern Territory
Temperament

Flight Pattern
short rapid wingbeats between canopy perches
Social Behavior
Usually in pairs or small groups, frequently joining mixed-species foraging parties in the canopy. Monogamous pairs defend small territories during breeding. Nests are domed, hanging structures woven from fine plant fibers and spider silk, with a side entrance. Both parents participate in care of the young.

Song Description
A high, clear, tinkling series of notes, often rendered as a repeated ‘wee-bill’ phrase. Song is swift and persistent, delivered from canopy perches while foraging or during territorial advertisement.
