Frequent prescribed burning of longleaf pine sandhill is necessary for maintaining Bachmans sparrow (Peucaea aestivalis) habitat. Late-breeding season burns (after June) and fire size are thought to influence survival and site fidelity of Bachmans sparrows. To assess habitat selection and effects of breeding season fire size (139-204 ha) on movements and survival of Bachmans sparrows, I radio-tagged 31 Bachmans sparrows in northern Florida during 2010-2011. Survival rate was 0.9660.037. Mature open longleaf pine stands were selected for home ranges above other habitat types, including sapling stands, regeneration areas, and oak hammocks. Fire size did not appear to negatively affect movements of Bachmans sparrows vacating burned areas except when suitable habitat was not available near their home range. Post-burn Bachmans sparrows were located in saw timber stands 90% of the time. Managers should consider fire size in relation to availability of suitable habitat and maintain frequent burning of old growth forests.
