Resumen:
Burrowing owls (Athene cunicularia) are known to include snakes and other reptiles in their diet (König et al. 1999. Owls: a guide to the owls of the world. Yale Univ. Press, New Haven, Connecticut, 462 pp.). On 25 October 2008, on Provincial Road 7, 20 km E Paso Cordova, Departamento El Cuy, Rio Negro Province, Argentina (39.1818ºS, 67.4053ºW, datum: WGS84; elev. 405 m), a set of regurgitated A. cunicularia pellets was collected near an active owl burrow. Laboratory study revealed remains of four snakes in the pellets, all identified as Leptotyphlops. The damage inflicted to the heads of the specimens made identification to species level difficult, but the coloration, morphometrics, and scale patterns of the individuals were consistent with L. australis (Cei 1986. Reptiles del Centro, Centro-Oeste y Sur de la Argentina, Mus. Reg. Sci. Nat. Torino, Mon. 4, 527 pp.). This represents the first record of predation on L. australis by the A. cunicularia.
