I've gotten quite a few responses on where to buy a duck stamp. I went online and found that the official duck stamp site reads that I can buy a stamp, but the link isn't working. So I found this site that carries the stamp. You might also contact your local post office to see if they are carrying the stamps (not all of them do). I think when I get back home, I might do an entry on how to purchase a duck stamp.
Thank you to all the birders who are willing to buy a duck stamp. The top reason I thank you is that you are helping to buy wetlands for a host of bird species. The other reason is that you are helping to break down the stereotype that birders are cheap and want others to pay for conservation--we need to get rid of that, almost as badly as we need to get rid of the notion that birders aren't cool.
