Thirteen-Striped Ground Squirrel |
||||||
 |
||||||
 |
||||||
| Ground squirrels, like this common species from the midwestern United States, are social animals. They live in colonies of burrows connected by a network of tunnels. While the burrows improve the quality of the land by bringing up soil from lower levels, they can be quite destructive to agricultural irrigation systems. | ||||||
