Acknowledgments

Many people provided published or unpublished information on eagles that we included in this species account. We could not have done this work without them and we have acknowledged them in the body of the document with the information they provided. Mary Jean Cowing and Courtney Frost provided essential assistance with literature reviews and references in the original (2002) version of this account and their past contributions greatly improved the current version. This is not a short document and its preparation required extensive time; we would, therefore, like to acknowledge the support of our families who endured our many hours working on this species account.
