Black-tailed Prairie Dog
Only recently did I recognize how similar looking are Richardson's Ground Squirrels and Black-tailed Prairie Dogs. I probably did not perceive it earlier because of the size differences, the former measuring 11 inches and weighing 6-26 oz, and the latter 13-17 inches and 21-53 oz, respectively, according to the Kaufman Field Guide.
FLICKR friend Erika's comment about the similarity prompted me to post the above Prairie Dog for comparison to the Ground Squirrel posted to the right. The comparison, except for size, would be even more similar if the Richardson's were not a youngster.
