Very little information is available for Peucaea botterii texana (Texas Botteri’s Sparrow) and nothing is known about its nesting ecology, in part due to its cryptic behavior and nesting strategies. Our goal was to examine the nesting ecology of Texas Botteri’s Sparrows and compare reproductive success between exotic and native grass- lands. We searched for and monitored nests in 2004 and 2005 on the King Ranch in southern Texas. We found no relationship in reproductive effort, nest characteristics, and plant species richness around the nest between grassland types. Vegetation surrounding Texas Botteri's Sparrow nests was significantly taller and denser in native grasslands than in exotic grasslands. Further research on nesting ecology for the Texas Botteri’s Sparrow is necessary to determine its habitat needs and its role as an indicator of grassland quality.
