Eating owl pellets by non-predator vertebrates is a rare and difficult-to-prove food chain relationship. In this paper, I reported the first record of a Spur-thighed Tortoise (Testudo graeca) eating a Eurasian Eagle-Owl (Bubo bubo) pellet with remains of a right Wood Pigeon (Columba palumbus) wing. Scavenging of food remains around owl nests by young tortoises may possibly explain the few cases of tortoise-eating Eurasian Eagle-Owls.
