European Sousliks are small ground squirrels with a uniform grey-brown, slightly spotted coat.
The eyes are quite large, the ears are small.
The legs are equipped with sharp claws which allow European Ground Squirrels to dig galleries in the ground.
European Ground Squirrels live in colonies in individual burrows. They hibernate between October and March after collecting provisions.
There is usually a litter of three to eight young in April-May.
Colonies have squirrels on the lookout standing on their back feet. They warn of dangers by whistling like marmots.
The species is in decline due to changes in land use and in particular the reduction of grazed meadows.
There is a less widespread related species, the Speckled Ground Squirrel (Spermophilus suslicus). It differs by numerous small, conspicuous creamy-white spots on its back.

Here is a squirrel on the lookout which may alert the colony by seeing a paparazzi approaching with his camera.
However, I don't remember hearing any hissing.

The ancient Greek city of Histria was long abandoned by its inhabitants. This is not entirely true because we have been able to see that it is currently inhabited by a small colony of European Sousliks.
