I recently aquired 4 Canada Geese and it is very difficult for me to keep them hidden. The guy never gave me a copy of his form to sell them so I am kinda screwed and it was a craigslist ad so good luck on me finding the guy again. After much research, I finally found this for for "Sale and Disposal" of migratory waterfowl permit form. The first part of it tells you what it takes legally to keep Canada Geese (as well as other migrants). I will have to check if mine have a toe clip or tatoo, they certainly aren't pinioned or banded. I thought this might be helpful to other people in my situation. The link is: http://www.fws.gov/forms/3-200-9.pdf
