Didn’t see any longspurs, but I did see some “striped gophers”, or Thirteen-lined Ground Squirrels. It sports a mighty robust name for such a tiny little beast. Even its scientific name is a mouthful: Spermophilus tridecemlineatus.
Ground squirrel on sentinel duty. The little burrowers are very vigilant against invaders, and post a guy to watch for interlopers. The guard stands erect, stretched to his full nine inch height, carefully watching the landscape. If something suspicious should appear, he alerts his brethren and all quickly disappear below ground.
Thirteen-lined Ground Squirrel range map. Ohio is truly a crossroads state, and we’ve got, or at least had, a strong prairie influence from the west. During the much warmer and drier Xerothermic Period of about 5,000 years ago, prairies expanded eastward, as did some of the characteristic prairie animals. This is the only Spermophilus ground squirrel that made it this far east; go to the western U.S. and there are twenty other species.
This map is of that ferocious digger, the American Badger, which probably digs out many a ground squirrel from their burrows. Note how once again Ohio is the eastern terminus for this prairie animal.
Some birds expanded eastward along with the mammals. This map depicts the range of the Bell’s Vireo, and once again the Buckeye State has the easternmost breeders. Nearly all records of nesters and territorial birds come from the former prairie regions of Ohio.
One more example – there are scads of others – of an eastward range expansion – the Lark Sparrow. Long-term shifts in temperature resulting in much more arid conditions, or much wetter periods, are a natural phenomenon, and the critters and plants migrate accordingly. Species like the Thirteen-lined Ground Squirrel are fascinating relicts of Ohio’s prairie past.
