Yellow Thornbill

The yellow thornbill (Acanthiza nana), formerly known as the little thornbill, is a tiny passerine bird endemic to the eastern coast of Australia. While currently listed as Least Concern by the IUCN, the general consensus is that the population is decreasing. Although similar to the striated thornbill and brown thornbill in both size and shape, the yellow colour of the yellow thornbill is more prominent. There is no sexual dimorphism, so that males and females look alike.
