Abstract:

Bortolotti recently proposed measurement of culmen length and hallux claw length as field characteristics suitable for identifying sex of Golden Eagles (Aquila chrysaetos). Unfortunately, these characteristics have not traditionally been collected on Golden Eagles, and extracting information on population or fledgling sex ratios from extant data sets is therefore difficult. Two characteristics commonly measured and reported in unpublished and published literature are body weight and/or footpad length. A technique using such measurements as a tool for a posterior identification of eagle sex could prove useful, and our purpose here is to present a multivariate method by which measurement or knowledge of these variables can be used to sex individual Golden Eagles.
