Anuran consumption pattern by Athene cunicularia: implications for the archaeological record of the Pampean region

The Burrowing Owl (Athene cunicularia) belongs to the family Strigidae and is widely distributed throughout the plains of South America. This species is seasonal opportunist and consumes a wide range of vertebrates and arthropods. This work evaluates the seasonal diet of the burrowing owl. Besides,...

description The Burrowing Owl (Athene cunicularia) belongs to the family Strigidae and is widely distributed throughout the plains of South America. This species is seasonal opportunist and consumes a wide range of vertebrates and arthropods. This work evaluates the seasonal diet of the burrowing owl. Besides, we provide a taphonomic characterization of the anuran bone prey remains that will help to identify the predator in fossil contexts. The study was conducted in a peri-urban sector in Olavarría city, Buenos Aires Province. Pellets and uneaten remains scattered around four owl burrows were weekly collected. Our results show that, among vertebrates, rodents were the main prey in winter, and anurans in summer. Burrowing owls produced little to moderate modifications on amphibian bone remains. The more frequent modifications of bone surface due to the digestive effects were polishing, thinning, and splitting.

La Lechucita de las Vizcacheras (Athene cunicularia) es un ave Strigiforme muy conspicua en las planicies de Sudamérica. Se caracteriza por ser una especie estacionalmente oportunista que consume una amplia diversidad de vertebrados y artrópodos. En este trabajo se evalúa la variabilidad estacional en la dieta de este predador y se brinda una caracterización tafonómica de los restos ingeridos y de carcasas de anuros que ayudará a identificar al predador en contextos fósiles. Los trabajos de campo se llevaron a cabo en un sector periurbano de la ciudad de Olavarría, provincia de Buenos Aires. Se recolectaron semanalmente las egagrópilas y restos no ingeridos hallados en asociación a cuatro nidos de lechucita. Los resultados obtenidos muestran que, entre los vertebrados, las presas principales en invierno fueron los roedores y en verano los anuros. Esta especie de Strigiforme produce modificaciones leves a moderadas sobre los especímenes óseos de anfibios. Entre los efectos digestivos identificados predominan el pulido, el adelgazamiento y astillamiento. A Coruja Vizcachera (Athene cunicularia) é um pássaro estrepitoso muito visível nas planícies da América do Sul. É caracterizada como uma espécie sazonalmente oportunista que consome uma grande diversidade de vertebrados e artrópodes. Este artigo avalia a variabilidade sazonal na dieta deste predador e fornece uma caracterização taphonômica dos restos ingeridos e das carcaças anuros que ajudará a identificar o predador em contextos fósseis. O trabalho de campo foi realizado em uma área periurbana da cidade de Olavarría, província de Buenos Aires. Os pellets e restos não consumidos encontrados em associação com quatro ninhos de corujas foram coletados semanalmente. Os resultados obtidos mostram que, entre os vertebrados, as principais presas no inverno eram os roedores e no verão os anuros. Esta espécie de Strigiforme produz modificações leves a moderadas nos espécimes de ossos anfíbios. Entre os efeitos digestivos identificados, predominam o polimento, o desbaste e a lascagem.
