Comparison of Inventory Methods for Wild Turkeys in South Texas

Line transect, mark-recapture, and 200-m strips counted from a truck were compared as methods of estimating numbers of Rio Grande wild turkeys (Meleagris gallopavo) on a 5,700-ha south Texas study area. Line transect produced the highest population estimate (N = 561, SE = 78), followed by 200-m truck strip (N = 312, SE = 53), and mark-recapture (N = 278, SE = 28). Compliance with underlying assumptions was assessed for each method. The line transect method was judged most promising for further evaluation.
