I can understand someone one who bought their mallard ducklings doing this but with all the people who come on here with ones they have found and have no clue where it came from should call a wildlife rehabber, don't just take a pair of scissors to it. Tame or not.The "mallards" in the case I am referring to originated at Tractor Supply. I am NOT providing a criminal suggestion because the birds came from a department store in the first place (not "the wild") It is unfortunate you decided I was "encouraging anyone to be able to just take a mallard from the wild and mark it themselves" by taking my comment completely out of context (the thread it addressed). The suggestion was provided IN THIS THREAD ONLY merely to relieve someone's apprehension. The concept of fraudulently marking wild birds that are property of the United States was never expressed or implied...on my end.
