Biology
The Barbary ground squirrel is a colonial animal and lives in family groups in burrows in dry grassland, bushy and rocky areas including disturbed agricultural land, or in dens among rocks. It needs access to water but is not found in irrigated fields. It tends to come out to feed early in the morning and again in the evening, retreating into its burrow during the heat of the day. It feeds on plant material and a major part of its diet is the fruit and seeds of the argan
