This species has a wee bill (the source of its name) and a tiny body to match. The weebill only grows to be about 3 to 3.5 inches long, and it beats out the spotted pardalote as Australia's smallest bird species. These petite birds travel in small flocks and live in almost any wooded area, though they love eucalyptus forests the most.
