“…This trend is much more evident during the non-breeding season than in the breeding season. 7 Spatial differences in the composition of diet have been described for many owl species such as the Magellanic horned Owl (Bubo magellanicus), 2 the Eurasian Eagle Owl (Bubo bubo), 83 the Tawny Owl (Strix aluco) 3 and the Barn Owl, 3,4 and bird of prey a. o. These differences are explained by a widespread premise, that many raptors (Falconiformes and Strigiformes) are highly opportunistic in the prey they eat.…”

“…1 The diet preferences of raptors with a broad range of distribution, shows spatial differences based on prey availability as a consequence of diverse environmental conditions and human activity within their hunting territories. [2][3][4][5][6] Korpimäki and Marti 7 explained that many raptors (Falconiformes and Strigiformes) are highly opportunistic in the prey they consume, and their diet thus reflects the distribution pattern of their prey. The winter diet of many raptors' species is wellstudied and shows several spatial differences in contrast with the breeding diet.…”

Owl diets undergo qualitative changes across the different regions of their area of distribution. During the four winters (from 2014–15 to 2017–18), Long-eared Owls’ pellets were collected at three winterroosts located at the southern part of Pannonian Plain, in the Serbian province of Vojvodina. In 8070 prey items from pellets, we identified 16 mammal and 32 bird species. The Common Vole was the dominant prey species with a proportion in a range from 27.4% to 71.6%. The Muridae family formed a supplementary part of the diet: Mus sp., wood mouse and harvest mouse, during all winters. Birds were also a major supplementary prey during winter 2014–15, comprising 10.6%. A comparison of our results with the diet of Long-eared Owls wintering at the northern Pannonian plain (southwestern Slovakia) indicated an increase the proportion of some species in the southern part. How different land uses in agriculture and environmental conditions may be reflected in the food supply are discussed in relation to the diet composition of Long-eared Owls and an environment whose is richer provides both growing diversity in the diet of these owls and an expansion of their food niche. Our study described the Long-eared Owl as opportunistic predators expanding their food niche in the presence of diversified prey.

“…During the breeding period, the two adults were observed feeding the nestlings with rodents and rabbits. The Magellanic Horned Owl has been described to primarily consume certain species of small mammals (Jaksic et al 1997, Iriarte et al 1990, Muñoz-Pedreros et al 2016.…”

The ability of a species to successfully adapt to urban areas is controlled by certain ecological limiting factors. Many owl species have a negative response to urbanization, while there are others that seem to tolerate, or even thrive, in urban environments. Here, we re- port a nest of the Magellanic Horned Owl (Bubo magellanicus) in a building balcony in a suburban area in the commune of Lo Barnechea, Santiago, Chile. The nest was found in the first week of August 2018, at first bearing a single egg. After 92 days of monitoring, two nestlings successfully abandoned the nest. The use of human-made structures by the Magellanic Horned Owl had not been previously recorded; con- sequently, this record evidences new nesting opportunities for this owl in urban areas, revealing a change in its reproductive behavior.

“…This last value is at odds with the latitudinal trend proposed by Jaksić et al (1986), in terms that diversity of prey in the owl's overall diet decreased steadily towards southern latitudes. Recently, Muñoz-Pedreros et al (2017) re-analyzed this purportedly latitudinal variations in diet of this owl species including a greater number of localities (N = 5) but no clear latitudinal pattern was detected. Most likely, results from all studies above may reflect the local availability and/or spectrum of prey at the time when diets were evaluated.…”
