This decline also is occurring in areas with apparently ample habitat such as the Rolling Plains of Texas, USA. The goal of our study was to examine the efficacy of translocating wild-trapped bobwhites into recently depopulated areas in the eastern Rolling Plains as a method of restoring population size. Our objectives were to document survival (spring-summer and annual), reproductive efforts, and site fidelity of translocated bobwhites and compare relative abundance of bobwhites between release and control sites to evaluate the efficacy of translocation. We translocated 409 wild bobwhites (n ¼ 186 radio-marked F) to 2 sites in Shackelford and Stephens counties, Texas, during March 2013 and 2014. Spring-summer (Mar–Sep) survival ranged between 0.32 and 0.38 (n ¼ 186 bobwhites), and annual survival ranged between 0.19 and 0.23 (n ¼ 186 bobwhites) during 2013–2015.
