examine the impact of patch fragmentation and size on occupancy. They found that occupancy was very strongly correlated to percent of habitat within 3 kilometers. This sensitivity to habitat in the surrounding landscape may be related to dispersal but is not yet understood. Territory and density Territory size of Bachman's sparrows varies. In Missouri glades, reports of average Bachman's sparrow breeding territory range from 1.5 acres (0.62 ha, n=13) to 7 acres (2.9 ha, n=7). In loblolly and shortleaf pine plantations of central Arkansas, mean home range size (n=25) during the breeding season was 6 acres (2.5 ha). In on a south-central Florida site with saw palmetto and scrub palmetto (Sabal etonia) interspersed amongst threeawn (Aristida spp.), Bachman's sparrow territories (n=6) averaged 12.5 acres (5.1 ha). In winter (November–January), the average home range size of 8 Bachman's sparrows was 1.6 acres (0.65 ha) in the dry prairie of central Florida. Bachman's sparrow density during the breeding season has been estimated in several habitats. On clearcuts of various ages with relatively abundant loblolly pine in eastern Texas, maximum Bachman sparrow density was 1.9/10 ha. In South Carolina, Bachman's sparrow densities ranged from 0 to 0.48/ha across sites of different ages and management regimes. In Georgia, Bachman sparrow densities ranged from 0 to 0.92 birds/ha on sites ranging from an open field to middle-aged and mature forests composed primarily of loblolly pine. In a south-central Florida community composed of saw palmetto, scrub palmetto, and threeawn, Bachman's sparrow density averaged 1 male/33 ha. In dry prairie of central Florida, Bachman's sparrow densities varied from 0.92 to 3.24 territories/10 ha across sites and years. Bachman's sparrow densities calculated from breeding bird censuses in longleaf pine forests was >15 territories/40 ha, while densities from winter bird population studies were from 6 to 10 individuals/40 ha. Food habits Bachman's sparrows forage on the ground for plant seeds and arthropods. In a predominately loblolly and shortleaf pine habitat of eastern Texas, all Bachman's sparrow foraging observations were on the ground and a literature review states that Bachman's sparrows rarely forage in shrubs. Reviews and an investigation of the Bachman sparrow's diet in eastern Texas summarize the species that comprise the Bachman's sparrow's diet. A variety of grass seeds such as panicgrasses, bristlegrasses (Setaria sp.), crowngrasses (Paspalum spp.), and threeawns are eaten by Bachman's sparrows as well as seeds of several other taxa, including blueberries (Vaccinium spp.), pines,
