“…Our research shows that long-eared owl occurrence is strongly positively correlated with the area of primary foraging habitat—grassland. The original habitat of long-eared owls was forest steppes ( Mikkola 1983 ; Barashkova et al 2013 ), which in Europe have been replaced by farming landscapes, which provide suitable hunting habitats ( Getz 1961 ; Mikkola 1983 ; Holt 1997 ; Henrioux 2000 ) and nesting sites ( Mikkola 1983 ; Henrioux 2002 ; Lövy and Riegert 2013 ). The present work also indicates that grassland fragmentation has little negative impact on nest site selection in long-eared owls.…”

“…Wooded areas, however, are probably an unsatisfactory hunting habitat for this species ( Getz 1961 ; Mikkola 1983 ; Henrioux 2000 ). Moreover, telemetric studies have shown that foraging birds avoid urban greenery like parks, which in their structure ( Lövy and Riegert 2013 )—thinly distributed trees and plenty of grassland—to some extent resemble forest steppes, the natural biotopes of long-eared owls ( Mikkola 1983 ; Barashkova et al 2013 ). It may be difficult for owls to hunt in parks because of disturbance by humans and their dogs ( Hathcock 2010 ; Cavalli et al 2016 ).…”

“…Long-eared owl Asio otus is widely distributed in the northern hemisphere and has a large population size ( BirdLife International 2016 ). The original habitats of this species are forest steppes ( Mikkola 1983 ; Barashkova et al 2013 ), from which population expanded into farming landscapes, sparse woodlands, and human-dominated habitats ( Henrioux 2000 , 2002 ; Martínez and Zuberogoitia 2004 ; Aschwanden et al 2005 ), including towns, cities, and their suburbs ( Zhang et al 2009 ; Göçer 2016 ; Milchev and Ivanov 2016 ). In Poland, first records of long-eared owl nesting in towns and cities come from the 19th century and presently it is a widespread breeding and wintering bird in urban environments of the country ( Tomiałojć and Stawarczyk 2003 ; Dziemian et al 2012 ; Turzanska and Turowicz 2014 ).…”

Noise, an obvious effect of urbanization, has a negative impact on animal vocalizations and the hunting efficiency of acoustic predators. However, the influence of noise pollution on the spatial distribution of populations remains understudied. The aim was to assess the factors shaping the distribution pattern of an acoustic predator (long-eared owl Asio otus) in an urban–farmland matrix. We hypothesized that the probability of an acoustic predator occurring decreases with growing nocturnal noise emission. This owl survey was conducted in Kraków (S Poland) on 79 randomly selected sample plots (1 km × 1 km). Six habitat variables (area of parks, woodlands, grassland, arable land, habitat diversity index, and noise pollution) were identified and correlated with the probability of the species’ occurrence. Proximity to pedestrian routes and roads, habitat fragmentation, and noise intensity was also defined at nest sites and random sites. Long-eared owls occurred on 37% of the sample plots. Occupied plots had a greater area of grassland and arable land as well as a lower level of noise pollution than the unoccupied ones. A multivariate model revealed that area of grassland and nocturnal noise emission was significantly correlated with the probability of long-eared owls occurring and that the high probability of occurrence recorded on plots with large areas of grassland was reduced by noise pollution. The noise intensity recorded at nest sites was also significantly lower than at random sites. This study suggests that apart from habitat factors, the distribution of acoustic predators in an urban matrix is driven by noise pollution. This highlights the importance of proper landscape management, that is, maintaining large grassland areas and preventing noise from increasing within them.

РезюмеПриведены данные по встречам хищных птиц в Восточно-Казахстанском мелкосопочнике и Северном Прибал-хашье, собранные главным образом во время полевых исследований в мае-июне и сентябре 2013 г., а также в марте и в мае 2012 г. Всего отмечено 15 видов соколообразных: степной орёл (Aquila nipalensis), беркут (Aquila chrysaetos), могильник (Aquila heliaca), орёл-карлик (Hieraaetus pennatus), змееяд (Circaetus gallicus), курганник (Buteo rufinus), черноухий коршун (Milvus migrans lineatus), степной лунь (Circus macrourus), лу-говой лунь (Circus pygargus), болотный лунь (Circus aeruginosus), ястреб-перепелятник (Accipiter nisus), ба-лобан (Falco cherrug), степной дербник (Falco columbarius pallidus), степная и обыкновенная пустельги (Falco naumanni, F. tinnunculus) и четыре вида совообразных: филин (Bubo bubo), болотная сова (Asio flammeus), домовый сыч (Athene noctua) и сплюшка (Otus scops). Для некоторых видов описаны особенности гнездования (данные о расположении гнёзд, размножении).
