Two of my labmates study chipmunks. Recently they have been working with an engineer to develop a small tag that they can attach to a chipmunk to record the chipmunk’s movements. This, if it works, will let them “see” what the chipmunk is doing without actually watching–and bothering–the chipmunk, which would be great: one of the difficulties of behavioral ecology is that, for animals as for subatomic particles, observing the thing often affects the very nature of that thing.
Part of developing this tag is being able to check how well it works. Unfortunately, our lab doesn’t have any chipmunks just hanging around on which to test the tag. So instead, for an unofficial, exploratory test run, we recruited one of my domestic mice.
