Recaptures were ≤ 320 m from original banding locations, which is consistent with the supposition that Florida Grasshopper Sparrows are sedentary. This population of the endangered Florida Subspecies appears to be longer-lived than Grasshopper Sparrow populations in other parts Of the species' range and may have different demographic patterns. Long-term studies are Needed to confirmthis. 收起
