We estimated summer-fall (15 Jun-20 Oct) survival for 32 adult and 96 fledged young American woodcock (Scolopax minor) radiotagged in eastern Maine during 1982-84 using single-interval, multiple-interval, and nonparametric (product-limit) methods. Single-interval survival estimates were 0.90, 0.88, 0.57, and 0.73 for adult males, adult females, young males, and young females, respectively. Multiple-interval survival estimates (0.93, 0.88, 0.63, and 0.71) and product-limit estimates were similar (0.92, 0.90, 0.60, and 0.69). Within each age class, male and female period survival was not significantly different for any method. However, point estimates of survival for young females exceeded those of young males by 0.08-0.16. Regardless of sex, adults exhibited higher summer-fall survival (range = 0.89-0.92) than young woodcock (range = 0.64-0.68). Age-specific variation in survival was caused by different predation rates that may be related to age-specific differences in mobility. The survival rates sustained by young woodcock during our study were similar to 4-month rates derived from annual survival estimates that assume constant mortality throughout the year. The high summer-fall survival estimates exhibited by adult woodcock suggest that most of their annual mortality occurs during another season.
