Identification of Peregrine Falcons Using a Computerized Classification System of Toe-Scale Pattern Analysis
Individual Peregrine Falcons (Falco peregrinus) may be identified by visually comparing their toe-scale patterns. However, these comparisons are tedious when dealing with large numbers of birds. We developed a computerized classification system to facilitate the identification process. The classific...
