Survival patterns of coyotes (Canis latrans) in southern Texas were studied from 1974 to 1982. Three estimates of annual survival rates of adult (≥1.5-year-old) coyotes ranged from 0.68 to 0.70. A mean annual survival rate of 0.42 for juveniles from 0.5 to 1.5 years of age was estimated by the product-limit method. Juvenile survival was lower (P < 0.01) than adults during the cool season (Nov-Feb). Fifty-seven percent of 35 mortalities of radio-collared coyotes were attributed to human-related factors (shooting, trapping, road fatalities). A greater proportion of juvenile females egressed from marking sites than juvenile males or either sex of adults. Comparison of autumn and spring population age ratios implicated an age bias in sampling.
