【 摘 要 】

Ridges on the internal side of the upper bill tip (i.e., ?filing ridges?) of parrots and some cockatoos form patterns that are characteristic of genera and, therefore, can be used for the classification of parrots and cockatoos.These patterns are also individually variable and, thus, could be used to fingerprint individual parrots.The objectives of our project were to evaluate the degree of individual variability and to develop a method and algorithm for registering and comparing the patterns of ridges by using a rigid registration technique. Within the data sets, we have been able to successfully identify each anonymized specimen using this method.For 22 of the 27 anonymized specimens, we found a degree of magnitude (the total error taken as the sum of distances between corresponding points) to be on the scale of 101 or greater between the match with the correct specimen and the match with all other members of the data set via a squared residual error assessment.For the remaining specimens, instances occurred in which the difference was smaller for two birds, but the correct bird was identified, nonetheless, while accurately ruling out over 90% of the incorrect bird matches.
