Ecology and Annual Cycles of Buntings (Emberizidae, Aves) in Northwestern Siberia as a Reflection of Adaptations to Subarctic and Arctic Conditions

The features of the annual cycles and ecology of buntings from the Lower Ob region and Yamal Peninsula have been compared in this paper. Annual cycles have much in common in buntings. The differences in the programs of the annual cycle are generally observed in the post-breeding period. These differences concern the timing of the onset of the postjuvenile molt and its completeness, the type of molt control (photoperiodic or endogenic type), the duration of molts, the degree of the combination of postnuptial molt with nesting, and the combination of the state of migration and molting.
