We monitored return rates of 114 breeding Henslow's Sparrows (Ammodramus henslowii) on mowed and unmowed areas on a reclaimed surface mine during seven breeding seasons. We observed 15 returns (13%) among 10 individuals (9%), all on unmowed areas. No individuals banded on mowed areas were observed in subsequent years on the same areas. Return rates increased slightly when hatching year birds were excluded. No individuals banded during their hatching year were subsequently seen again. Three of 10 returning individuals were observed during multiple years. These observations support previous findings that reclaimed surface mines provide adequate nesting habitat for Henslow's Sparrows. Early-season mowing as a management strategy should be used with care.
