GEOGRAPHICAL VARIATION IN SIZE OF WHITE-BROWED BABBLERS IN WESTERN AUSTRALIA

WA Museum Records and Supplements | Updated 1 decade ago

Abstract: Australian babblers are mainly birds of dry country habitats, such as acacia scrub although they may also occupy eucalypt woodland (Blakers et al. 1984). In Western Australia, the White-browed Babbler Pomatostomus superciliosus (Vigors and Horsfield) occurs north to the Tropic of Capricorn but is not found on the Swan coastal sandplain or in the dry sclerophyll forest of the South-West (Ford 1971). However, populations of White-browed Babblers are found in the wet sclerophyll forest of the South-West, especially where the understorey contains thickets of Acacia or Trymalium.
