- Abstract
Jerdon’s Babbler <italic>Chrysomma altirostre</italic> is a threatened Oriental grassland specialist passerine heavily affected by habitat loss. Its now-relictual range spans from Pakistan to Myanmar covering three poorly-studied subspecies. Our study of subspecific differentiation revealed limited range-wide mitochondrial divergences, suggesting that mountain ranges and other geographic barriers may not have been insurmountable obstacles to inter-subspecific Pleistocene connectivity of this highly specialized grassland bird. For the westernmost subspecies <italic>scindicum</italic>, we report on phenotypic differentiation consistent with Gloger’s Rule, and ecomorphological adaptations to arid environments requiring increased mobility.
