Ruffed grouse nutrition and foraging in the southern Appalachians
MetadataShow full item record
Intake rate of leaves was an asymptotic function of bite size when the density of bites did not limit intake. Intake rate of leaves decreased at plants densities < 322 plants/m2. The maximum intake rate of leaves was 25% of the intake rate of aspen buds observed in wild grouse (Huempfuer and Tester 1988). Intake rate of raisins was an asymptotic function of bite size and was 20 times greater than the intake rate of leaves. Ruffed grouse in the Southeast must forage for> 100 min/day under ideal conditions to satisfy energy requirements.
