Representatives of the animal kingdom are also of the Southern type, some species occur only in this region, others have limited distribution. In 1997, the Reserve Tisata and its adjacent buffer zone and protected area "Moravska" were officially declared Important Bird Area called, "gorge". Because of its international importance for conservation of birds Tisata is the most representative of the five places in Bulgaria, announced the conservation of species typical of Mediterranean biogeographical region - Spanish Wheatear (Oenanthe hispanica), rock partridge (Alectoris graeca), large olive Mockingbird (hippolais olivetorum), small black-headed warbler (Sylvia melanocephala), rock nuthatches (Sitta neumayer), Shrike (Lanius nubicus) and Black-headed Bunting (Emberiza melanocephala).
