Document Summary
Ptt data were less accurate than vhf, but these errors were not large enough to account for the large differences in estimates of territory size between the 2 data sets: the larger estimates of territory size derived from ptt data resulted from a combination of more frequent locations, greater number of locations, acquisition of ptt locations when it was impractical to obtain vhf locations, and location error associated with ptt locations. This risk can be minimized by using adjustable harnesses and collars to custom fit each bird, and by adding a weak link that would allow the device to detach if entangled: nest success and survival appeared to improve as transmitters became heavier, and there didn"t seem to be much effect of a transmitter"s weight on a bird in general. The ability to accurately assign adult white tailed deer to specific year age classes is important in making management decisions and interpreting managements and research results.
