Regional population inferences for the American woodcock

Woodcock (Philohela minor) bandings and recoveries from 1967 to 1977 were analyzed from two large banding reference areas corresponding to existing Eastern and Central harvest units. We examined temporal, age-specific, sex-specific, and geographic variation in both survival and recovery rates, using recently developed stochastic models. Survival rate estimates for females were higher than those

Examination of woodcock nest sites in central Pennsylvania

Evidence is given to support Iow selectivity in choice of nest sites by woodcock (Philohela minor). Habitat characteristics measured at 30 woodcock nest sites were compared with non-nest control sites in Huntingdon County, central Pennsylvania. Mean nest density per year was 1/4.8 ha within the 54-ha study area. Of 14 characteristics measured, higher shrub-stem density at nests was the only variab
