A test of an osteologically based age determination technique in the DoublecrestedCormorant Phalacrocorax auritus

Double-crested Cormorant (Phalacrocorax auritus) Science Article 15


The ability to determine the age of birds accurately from their skeletons would be useful not only for population biology and wildlife management research but for avian palaeontological and archaeological analyses as well. While accurate osteologically based age determination techniques are available for some amphibians and reptiles (Peabody 1961, Reid 1981), fishes (e.g. Bagenal 1974, Summerfelt & Hall 1987) and mammals (e.g. Morris 1972, Grue & Jensen 1979, Lieberman 1994), none is well established for birds.
