Description General Info
Description
Ranging from 17 cm to 21 cm in length the white-browed babbler is the smallest of the Australian babblers. It is a medium-sized terrestrial bird with a long and decurved bill. The wings are short and rounded in shape adjoining to a plump, full body which is similar, but slightly smaller than the chestnut-crowned or Hall's babbler. The tail is long and graduated ending with a rounded tip. The gregarious nature of this species means that the tail is often fanned or raised or any mix of the two. There are many variations to colour, however the adult babbler generally varies from a dark grey-brown to solid dark brown with distinguished white supercilium and dark brown eye stripe. The underside is usually lighter in colour, varying from light grey or white to light brown, sometimes lighter for females, but generally sexes are similar. Juveniles often have more pronounced dark plumage with a chestnut or cinnamon motif, especially on the underside. Breeding adult males may sometimes have a more pronounced brown ‘cap’ compared to females or juveniles.

Feeding Habits
White-browed Babbler consumes insects, spiders, amphibians, crustaceans, reptiles, fruits, seeds, and nuts, primarily foraging on the ground. Adults use a base log or branch near their nest for feeding and seldom stray far, while unpaired juveniles are more explorative.
Habitat
White-browed Babbler is primarily found in the southern regions of Australia, where it occupies a variety of habitats including dry sclerophyll woodlands, shrublands, and semi-arid grasslands. These birds seek dense understories, such as those provided by shrubs or spinifex, for nesting and protection. Their habitat preferences span across a range of ecological vegetation classes, from arid desert landscapes with mulga and acacia to open forests with eucalyptus. Adaptability is evidenced by their presence in areas with human infrastructure. White-browed Babbler is commonly associated with dense underbrush dominated by Acacia and Banksia in native forests and woodlands, and is also found in mallee ecosystems and shrubby heathlands. Occasionally, white-browed Babbler inhabits roadside vegetation, agricultural land, and even golf courses.

Distribution Area
Populations of white-browed babbler live throughout the southern mainland of Australia. Generally they are located south of the tropic of Capricorn from the east to west coast of Australia. The populations that exist in the central areas of Australia tend to be more isolated than those nearer to the coastline.
Species Status
Commonwealth status: Not listed State of Victoria: least concern State of South Australia: least concern State of Western Australia: least concern Given the large range of the species the IUCN has deemed that the population of white-browed babblers in Australia does not approach the thresholds for vulnerable under the range size criterion. The size and density has generally been in decline since the 1970s although the rate at which this is occurring suggests that there is little need for concern for the species. Given that the persistence of the species is of little concern there are no conservation efforts tailored specifically for it, however there is significant decline of other species in the ecosystems which the white-browed babbler inhabits. Many of these studies suggest that remnant vegetation is integral to the health of these ecosystems, and that their removal can cause higher levels of competition in an area. This leads to interspecies competition for remnant vegetation and the species that rely on them decline in number. Others suggest that the generalist style of feeding is best suited to these degraded landscapes, and therefore the white-browed babbler is least susceptible to degraded conditions.
