One hundred and twenty white-tailed deer (Odocoileus virginianus) fawns were captured in Lavaca and Gonzales Counties in 1971 through 1973. The fawns were 1 to 18 days of age and weighed 1.8 to 6.8 kg. They were observed during May and June in Lavaca County and June and July in Gonzales County. The mean home range of Lavaca County fawns was 32.5, 31.7, and 32.9 ha in 1971, 1972 and 1973, respectively. In Gonzales County, the mean home range was 34.3, 37.9, and 16.9 ha, respectively. Mortality rates were 25, 50, and 35 percent in Lavaca County, and 90, 35, and 10 percent in Gonzales County in 1971, 1972, and 1973 respectively; combined fawn loss was 47 percent. Predation accounted for 50 percent of mortality. Disease and starvation accounted for 34 percent. Sixteen percent of the deaths were undetermined. Significant correlations were noted between a declining deer population on poor range and fawn survival. Also, areas that were consistently overpopulated but had not suffered extreme droughts experienced moderate levels of fawn mortality each year.
