The population of Little Owl decreased over much of Europe including Poland, where it's status has not yet been elucidated in full. We compiled data from 13 censuses carried out from 1982-2005 at a 12 km2 study plot situated in an agricultural area in the north-western outskirts of warsaw in Central Poland. We observed a significant decline in the Little Owl population, leading to its disappearance from the study site. The population dynamics was not correlated with the weather factors analysed (snow cover and thickness, air temperature for December-March period, precipitation for March, May and June), which indicates that climate change was not a direct cause of the decline. There were no substantial changes in the land use structure at the study area. We conclude that the reduction in nesting sites and decreased food availability are the potential factors of the Little Owl decline.

A change of land use is often cited as a causal factor in the decline of many species of farmland birds. Populations of the Little Owl (Athene noctua Scop., 1769) have notably decreased throughout Europe in the last 60 years, including the Czech Republic. The aims of this study were to estimate the recent population trend of the Little Owl and to analyze the importance of altitude and grassland habitat within Little Owl territories. The population trend of the Little Owl in the Czech Republic has still decreasing tendency. The population density dropped from 0.33 breeding pairs (bps) 10 km[^-2] to 0.12 bps 10 km[^-2] in the first (1993-1995) and second (1998-1999) monitoring program, respectively. The decline is apparent also from results from last Little Owl monitoring program which were carried out in 2005.2006 on 35 study plots (4607 km[^2]). The average population density was estimated at 0.1 bps 10 km[^-2]. A distinct feature of these recent populations is that they occur in the places with relatively high local density (core areas) in comparison to the surroundings, which are unoccupied. At present, the Little Owl rarely breeds in natural tree cavities, but rather the majority of nesting sites are situated in human artifacts, especially within agricultural objects. Areas in which the Little Owl occurs have a significantly larger proportion of grasslands and are situated at lower altitudes. We suggest that the changes in agricultural landscape associated with disappearance of traditional farming management of grassland habitats, forceful pasturage and regular mowing were the main factors in this long-term population decline. The recent decrease of Little Owls could be also the consequence of the existence of small isolated populations in which mortality is not balanced by immigration from surrounding areas.

Little Owl is a rapidly declining farmland species across Central Europe, however its population status is poorly known in Hungary. The main aim of this study was to determine the distribution and population density of Little Owl in Hortobagy National Park (northeastern Hungary), which is characterized by a high proportion of grassland habitats. During March and April of 2011–2012, the Little Owl occurrence was surveyed using tape-recorded stimulation in 245 sampling points in an area of 489 km². In total, we recorded 245 calling males with relative positive occurrence of 75.5% in an individual sampling point. The average nearest neighbour distance of two calling males was 553.6 meters (min. = 70 m, max. = 3100 m). The average population density of Little Owls was 5.01 calling males/10 km², however this could reach up to 85.97 calling males/10 km² in 3.06 km² locally. Residential buildings and farms were the main expected breeding places in our study area. High density of the Little Owl in the study area is probably influenced by traditional pastoral management, extensive agriculture and high proportion of grasslands. The particualar role could be atributed to presence of short-sward pastures around human settlements, considered to be crucial for the species survival in Central Europe. Further monitoring of the Little Owl is necessary to assess its current population status across various parts of its distribution range.

Rozwój cywilizacji człowieka prowadzi stopniowo do niszczenia i przekształcania siedlisk przyrodniczych. Wraz z nasilaniem się tego procesu wiele gatunków zwierząt wycofało się z otoczenia człowieka, a inne adaptowały się do zmienionych lub całkowicie „sztucznych" warunków. Aspekt miasta jako środowiska życia fauny jest w wymiarze procesu ewolucji zjawiskiem bardzo „młodym". Specyficzna biologia sów związana z nocną aktywnością sprawia, że są one na terenie miast nieco słabiej poznane niż inne gatunki ptaków. Według dostępnych źródeł początki gnieżdżenia się sów w miastach na ziemiach polskich sięgają średniowiecza. Większość danych z XIX wieku pochodzi ze Śląska oraz terenów zaboru rosyjskiego. Publikacje wydane po II wojnie światowej są liczniejsze i dotyczą głównie większych miast w Polsce. Znaczną część literatury stanowią opracowania atlasowe miast. Dotychczasowe badania nad sowami w miastach koncentrowały się głównie na opracowaniach faunistycznych i analizie składu pokarmu. Znakomita część opublikowanych prac dotyczy wybiórczości pokarmowej i różnych czynników (temperatura, opady, pokrywa śniegowa, występowanie w centrum miasta lub na obrzeżach), które modyfikują aktywność łowiecką i w efekcie dietę tych ptaków. Inne zagadnienia są potraktowane marginalnie lub nigdy nie były przedmiotem badań w miastach. Dotyczy to przede wszystkim sukcesu lęgowego, wielkości i charakterystyki zajmowanego terytorium, jego zmian w trakcie całego sezonu, dyspersji polęgowej, fenologii, badań toksykologicznych, pasożytów, wpływu hałasu, zanieczyszczeń oraz różnorakich odmienności etologicznych populacji sów żyjących w miastach. Innym, bardzo ważnym zagadnieniem jest czynna ochrona gatunków sów występujących w miastach, takich jak: płomykówka Tyto alba, pójdźka Athene noctua, puszczyk Strix aluco czy uszatka Asio otus. Dalsze badania pozwolą na lepsze poznanie wymagań i zagrożeń miejskich populacji sów oraz pozwolą zoptymalizować praktyczne formy ich ochrony.

The development of human civilization gradually leads to the destruction and conversion of flora and fauna habitats. With the escalation of this process, many species have withdrawn from the human environment but others have adapted to converted or completely artificial conditions. The aspect of cities as an environment for fauna is a "young" phenomenon in terms of evolution. Owls as birds with specific biology associated with nocturnal activity are less investigated compared to other species of birds. According to available sources, the origin of owls nesting in the Polish cities date back to the Middle Ages. Most of the data from the nineteenth century came from Silesia and areas invaded by Russia. More papers were published after World War II and they concern mostly larger cities in Poland. A significant part of the literature is represented by atlases of cities and towns. The previous research on owls in the cities focused mainly on the fauna and food composition. The majority of published works concerns food selectivity and various factors such as temperature, precipitation, snow cover, occurrence in city centres or on their outskirts, which affect the preying activity and consequently the diet of these birds. Other issues are neglected or have never been studied in the cities. This applies in particular to breeding success, the size and characteristics of the occupied territory, its changes during the season, the post-breeding dispersal, phenology, toxicological studies, parasites, the effect of noise, pollution and ethological differences of the population of owls living in cities. Another very important issue is active protection of species in cities such as the barn owl Tyto alba, little owl Athene noctua, tawny owl Strix aluco and long-eared owl Asio otus. Further research will allow a better understanding of the requirements and risks to urban populations of owls and will optimize the practical forms of their protection.
