If you want to do some scoring on 1cy and 2cy birds in your local park, riverside or else, and you need a form to score these data on, you may be interested in this checklist:

If it doesn't work: click this http://www.gull-research.org/miscellane ... 009-1).mht
Originally, its an excel. We just copied 100's of these prints, and used them in the field. You need 1 form for 1 individual.
Hope it will work for you as well, we have used it for 100's and 100's of michahellis, graellsii & argenteus. If you have problems with the abbreviations, or want to know more about the categories used, please leave a reply here, so other people may benefit from it as well.
