First of all, find the Ermine by watching a scrum of kids chasing something around.
Position yourself in a place where you can watch the action, but where you are in no way hidden from the Ermine.
Next, pay no attention to your camera settings, or if you do make sure it is set on a slow shutter speed. Spot, one shot focus setting is desirable as well, to make sure that your auto focus does not track said Ermine.
Marvel at just how quick Ermine are, especially when chased by a group of kids. Marvel also at the Ermine's penchant for never pausing for more than a fraction of a second.
Trash the unusable photos upon getting back to the computer, and never, ever share them like this.

Thank you for the tips on how not to photograph an ermine. Even with your “not to” instructions and examples, the shots were not tooooo bad.
Somewhere between pretty good and amazing, considering the circumstances…
Not bad really! I have the same problem with chipmunks around here.
Suurrrre they weren’t Emma. Thanks.
Thanks Mark, but they won’t be appearing in National Geographic anytime soon.
I haven’t seen a chipmunk in so long Casey, I’m not sure what they look like anymore. Lemmings on the other hand…
