Similar, but Different

A couple more inhabitants of Echo Lake were observed during our brief stop.

The Colorado Chipmunk (Tamias quadrivittatus):

and the Golden-mantled Ground Squirrel (Spermophilus lateralis):

I hope I got the ID’s right on these two mammals! As you can see, there clearly is a difference in the stripe patterns. Also, the Colorado Chipmunk has a somewhat elongated, pointed head as compared to the ground squirrel’s. And the Colorado Chipmunk, although a bit farther away, appeared to be significantly smaller than the ground squirrel. But both were fun to watch!
