Ground Squirrel Reproduction
When ground squirrels emerge from hibernation the first thing on their mind is sex. Is it surprising that the males emerge a few weeks earlier than the females? They just can't wait. This is their big chance because the females only produce one litter per year. (I've heard from a few biologists that they sometimes mate again if they lose their litter, but I can't find that in writing.)
Now is the time to prepare for the new wave of destructive diggers. After 6 weeks of growing up in their burrow, the litters will emerge from their nests. The young look like miniature lighter colored versions of the adults. They stay near the nest until about 6 months of age. Then young ground squirrels will move into old abandoned burrows or scatter off to new territory. Ground squirrels have been known to travel up to 5 miles to start a new colony.
After they find the best location for their burrow, most ground squirrels will then get ready for hibernation. Then they get to repeat the cycle all over again. Let's just hope that it isn't repeating on your land. Oh, and I forgot to mention that ground squirrels live up to 6 years in the wild.
