and loblolly pine plantations of Arkansas were built on the ground. Most nests (70%) were built at the base of bluestem clumps, although nests were found at the base of small trees, forbs, and other grass species. Bachman's sparrow nests are dome-shaped with an opening typically oriented to the north. However, there is some variation in nest shape and on the Arkansas study site above, only 7% of nests were not either partially or completely domed. Bachman's sparrow nest shape may vary geographically, as nests found farther north in their historic range were infrequently domed. Clutch size varies from three to five. Average clutch size on a site in Arkansas was 3.9, while in a longleaf pine community in South Carolina mean clutch size was 3.6. Both of these studies found significant (p≤0.02) decreases in clutch size as the breeding season progressed. On a dry prairie site in Florida (n=9) average clutch size was 3.44 and on another (n=5) it was 3.6. In shortleaf and loblolly pine plantations of Arkansas, females laid an average of 11.6 eggs (n=20) over the course of the breeding season. In shortleaf and loblolly pine plantations in Arkansas, females incubated eggs for 13 to 14 days. The average nestling period was 9 days, and the average period between fledging and independence was 25 days. Both parents care for the young during these periods. A review suggests that Bachman's sparrows probably breed the year after hatching. Bachman's sparrows exhibit some fidelity to breeding sites. Over a two-year period in shortleaf and loblolly pine plantations of central Arkansas, 6 of 34 adults returned to areas where they had a territory in a previous year. This varied across years, with a 29% return rate of adult birds banded in 1983 and none of the adults banded in 1984 returning to the site in 1985. No juveniles (n=60) returned to the site. Nesting success Values of nest success reported for Bachman's sparrows vary. Daily nest survival rate of Bachman's sparrow ranged from 0.89 to 0.96 across sites and years in the dry prairie of central Florida. On average 3.13 birds were fledged per successful Bachman's sparrow nest. Estimates of productivity ranged from 1.21 to 4.16 offspring per pair per year across sites and years. In a South Carolina longleaf pine community, daily survival rate of Bachman's sparrow nests in 1995 was 0.952, which was significantly (p=0.04) higher than the
