ABSTRACT

Resumen La lechuza de los arenales Athene cunicularia (Aves: Strigidae) se distribuye desde Canadá hasta Tierra del Fuego en América. Ocupa una gran variedad de hábitats naturales, ambientes urbanorurales y agroecosistemas. En el Perú residen tres subespecies A. c. nanodes, (Berlepsch y Stolzmann, 1892), A. c. juninensis (Berlepsch y Stolzmann, 1902) y A. c. cunicularia (Moliln, 1782). El presente trabajo, constituye una revisión de la bibliografía complementada con datos propios, con la finalidad de identificar el estado actual del conocimiento de la biología y estado de conservación de A. cunicularia con especial énfasis en las poblaciones que habitan en el Perú.


Abstract The Burrowing Owl, Athene cunicularia, is distributed from Canada to Tierra del Fuego in America. It occupies a wide variety of natural habitats, urban-rural environments, and agro-ecosystems. Three subspecies reside in Peru: A. c. nanodes (Berlepsch and Stolzmann, 1892), A. c. juninensis (Berlepsch & Stolzmann, 1902) and A. c. cunicularia (Molina, 1782). The present work constitutes a bibliography review, supplemented with our own data, to identify the current state of knowledge about the biology and conservation status of A. cunicularia; with special emphasis on the populations that inhabit Peru.

ABSTRACT

Estudiamos la dieta del búho terrestre Athene cunicularia punensis en cuatro territorios dentro del archipiélago de Jambelí, provincia de El Oro, suroeste de Ecuador, entre noviembre de 2015 y abril de 2016, mediante la recolección y análisis de 182 egagrópilas. Los artrópodos constituyeron el principal grupo-presa en frecuencia de aparición (86.5%), seguido por los mamíferos (12%) y las aves (1.5%). En cuanto a biomasa consumida, los mamíferos (Mus musculus y Rattus rattus) aportaron 58.5%, los artrópodos 33.2% y las aves 8.2%. No encontramos diferencias significativas de la dieta entre las cuatro parejas estudiadas. En este trabajo se confirmó el rol de Athene cunicularia como un importante depredador de plagas como roedores introducidos y artrópodos potencialmente dañinos.


The diet of Burrowing Owl (Athene cunicularia punensis) was studied in four territories in the Jambelí archipelago, El Oro, southwestern Ecuador, from November 2015 to April 2016, collecting 182 pellets. Arthropods were the main prey group in frequency of occurrence (86.5%), followed by mammals (12%) and birds (1.5%), but mammals (Mus musculus and Rattus rattus) contributed 58.5% of the biomass, arthropods 33.2% and birds 8.2%. No significant differences were found in the diet among the four pairs studied. Our study confirmed the important role of Athene cunicularia as predator of pests like introduced rodents and potentially harmful arthropods.

ABSTRACT

The aim of this study was to report the burrowing owl Athene cunicularia as a new host for the filarid nematode Pelecitus sp. in southeastern Brazil for the first time, as well as reporting the occurrence of this nematode species in the body cavity, near the cervical air sac and lung region. This study contributes towards knowledge of parasitism in Brazilian wild birds and an anatomical region of the host as an infection site for Pelecitus sp.


O objetivo do estudo foi relatar, pela primeira vez, a coruja buraqueira Athene cunicularia como um novo hospedeiro para o nematóide filarídeo Pelecitus sp. do Sudeste do Brasil, bem como a ocorrência desta espécie de nematóides na cavidade corporal, próximos à região dos sacos aéreos cervicais e pulmões. Este estudo contribui para o conhecimento do parasitismo em aves silvestres brasileiras e uma região anatômica do hospedeiro como sítio de infecção para Pelecitus sp.
