Reliability of Established Aging and Sexing Methods in Ruffed Grouse

Published methods for aging and sexing ruffed grouse (Bonasa umbellus) have not been tested on a large sample of birds from the Southeast. We evaluated several methods in a hunter-donated sample of 268 birds from eastern Tennessee. Age and sex determined by individual techniques were compared to necropsy findings. Results of aging techniques ranged from 3.3% to 39% error. Sexing error ranged from 1.3% to 24%. Results were generally not as accurate as those reported from the northern United States due largely to juveniles with adult traits and females with male traits. Use of most...


Evaluation of a Ruffed Grouse Reintroduction in Tennessee

Thirty-six ruffed grouse (Bonasa umbellus) trapped in eastern Tennessee were released in western Tennessee during fall and winter 1985-86. Birds were monitored by radio telemetry and/or observation through spring 1986. Drumming surveys were conducted in the spring of 1986 and 1987. Thirteen drumming logs were located. Two activity centers were delineated in 1986, and 4 in 1987. Characteristics of drumming logs and surrounding habitat are comparable with those reported in the literature.
