Grey-crowned Babbler

The breast color is usually used as the distinguishing morphological character between the subspecies, with a creamy white breast grading to mid-grey in P. t. temporalis and a mid to deep rufous brown breast in P. t. rubeculus. Other differences relate to brow coloration, facial bands through the eye, tail length and overall size. A zone of intergradation occurs between the two subspecies in north-central Queensland.
