“…Related to the consumption of mammals, a single individual represents a large contribution in biomass much higher than that provided by the invertebrates (Herse 2016), for this research it is reported as a new item within the diet of A. cunicularia to the "fat-tailed opossum mouse" (Thylamis sp. ), which had not been previously reported.…”

“…These grooming sessions were performed when they left burrowing (7-12 hours) and upon returning (16-17 hours), which would be due to a strategy to eliminate the ectoparasites taking advantage of the hours of higher temperature (Herse 2016), it has also been reported that they perform dust baths for this purpose, which were not recorded in this study. In the case of the grooming in the afternoon would be done to order the feathers and keep the heat at night.…”

“…Athene cunicularia have a generalist food habit, feeding on a wide range of prey that includes arthropods such as insects and arachnids, and vertebrates like small mammals, birds and reptiles, invertebrates being predominant (Nabte et al 2004;Vieira and Teixeira 2008;Roque-Vazquez et al 2017). Although there are numerous works related to the diet of this species in North America and semi-arid habitats in Latin America (e.g., Tommaso et al 2009;Carevic 2011;Limonggi 2014), little is known about their trophic habits of the species in Peru, and more specifically in the ecosystem of Lomas (Medina et al 2013) and even less of their behavior incorporating the use of trap cameras (Herse 2016;Riding and Belthoff 2018).…”

Abstract. Luque-Fernández CR. 2019. Diet and behavior of the burrowing owl (Athene cunicularia) in Atiquipa, an ecosystem of Lomas in the south of Peru. Biodiversitas 20: 137-143. The study of trophic and behavioral habits is a fundamental aspect in the knowledge of the natural history of species, especially for those that present a wide range of distribution and that have to adapt to the habitats and available resources that can find to survive. The diet and behavior of Athene cunicularia were studied in a peculiar ecosystem such as the lomas formation, on the arid coast of southern Peru. The analysis of regurgitated pellets from a family group of Athene cunicularia was used and complemented with the monitoring of behavior through the use of trap cameras and direct observations. The results show that the diet during the months of study was based on a high proportion of invertebrate beetles (Tenebrionidae) and scorpions, also finding remains of vertebrates, including rodents, birds and highlighting the presence of a species of marsupial mouse. On the study of behavior, marked and recurrent activities are established during the day for this species, where grooming sessions are frequently reported, as well as interaction with a possible predator of this owl species. These results contribute to the understanding of the trophic relationship and its role in the studied lomas ecosystem, which is added to the importance of this species in the conservation of diversity in desert ecosystems.

The wintering phase of the Western Burrowing Owl (Athene cunicularia hypugaea) life cycle has received little attention in the literature. Small numbers of Burrowing Owls have been observed and recorded since 2008 in the winter season in Cesar Chavez Park, a 90-acre peninsula that forms part of the waterfront of the City of Berkeley. The relative ease of observation in this setting allows study of their arrival and departure dates, selection of micro-habitats, tolerance of human presence, behavior in inclement weather, and response to avian and canine predator threats. Viewed over a decade, fewer owls arrived, arrived later, left earlier, and spent less time in residence. Most owls settled in shoreline rip-rap or in tall vegetation; only one fourth settled in short grass. Owls chose exposure to rain for as long as two days. Owls varied widely in tolerance to human proximity. Owls successfully dealt with avian predators, but displayed stress and in some cases became casualties of loose Canis lupus familiaris. Recommendations for habitat management follow.
