On 9/1/2012, I digiscoped some Forster's Terns visiting Riverlands Migratory Bird Sanctuary in Alton, Missouri. I thought they were all Forster's, until Bill Rudden pointed out that I might want to look again and see if there was a Common Tern amongst the bunch. And guess what? There was. Have fun finding the Common Tern. My wife Chrissy McClarren helped create this quiz. Thanks Bill!
