as long as fawns survived. Both Wood (1987) and Hirth (1977) 

 reported larger average and maximum group sizes for white- 

 tailed deer in prairie habitat and open river bottom habitat, 

 respectively, than we observed for mule deer. The perception 

 that mule deer are more gregarious than white-tailed deer may 

 reflect the fact that many reported studies of mule deer were 

 in relatively open habitat and/or were conducted during 

 periods of poor fawn survival.
