through May during all years. The variable recruitment rates 

 to autumn, early winter, and spring for fawns (Tables 4.1, 

 4.2, and 4.3) resulted in considerable variation in the 

 proportion of fawns in the population during any season or 

 year. 



Fawn: female ratios at birth pulse averaged 127:100 

 and ranged from 99 to 148 fawns: 100 females during 1975-1986. 

 There was an average of 74 fawns: 100 females during autumn, 

 but ratios varied considerably from 31 to 120 fawns: 100 

 females. During early winter, the average ratio dropped to 65 

 fawns: 100 females, within a range of 29-116 fawns: 100 females 

 (Fig. 4.8). In spring, the average was 39 fawns: 100 adult 

 deer and the range was 5 to 82 fawns: 100 adults. Conversion 

 of these data to fawn: 100 female ratios, based on estimated 

 numbers of males in spring populations, yielded an average of 

 50 fawns: 100 females with a range of 6 to 103 fawns: 100 

 females .
