This report is an updated version (including improved illustrations) of the original key. It is the first in a series to be issued by the British Columbia Conservation Officer Service, Ministry of Environment. Over the years, Conservation Officers have had the unique opportunity to gain first-hand experience in developing and refining techniques related to enforcement duties. A goal of this series is to make available, to a wider audience, the results of those experiences.
This particular report is the result of a workshop given by Wayne Campbell to the Convention on International Trade in Endangered Species of Wildlife Fauna and Flora (CITES) in Vancouiver 1987. Participants to the conference were from enforcement agencies throughout North American and all agreed that correct identification of birds of prey was critical for their work, especially during investigations. They also wanted simple keys, easy to understand, that could quickly and accurately be used by enforcement officers. The present keys have been developed to meet that end. Future reports will appear from time-to-time as new enforcement techniques are developed and other training techniques and information becomes available.
