This little Canada Goose was quite the character. It and five of its siblings were following mom and dad around St. Vrain State Park, Colorado recently. While the others were behaved, this one decided it wanted to practice the hissing that adult geese do when threatened. From one sibling to the next it would go up, open its mouth and stick out its tongue, and try to make the sound. Adults can be kind of mean and aggressive and if they hiss at you, you better give them some distance. Coming from this little one though, it was pretty comical.
