It is a resident bird of open areas, staying near nesting sites in winter. Its population is strongly influenced by food availability, weather conditions and several anthropogenic activities. One of the most important factors of these in recent decades has been road mortality. In this work, we processed data of roadkilled individuals and field observation records in the Csanádihát region in south-eastern Hungary from the period 1995–2022. In Battonya, we have been recording roadkill individuals since 1995, while observations of Barn Owl individuals from Kevermes have been available since 2005. The species is a regular, but scarce breeder in the area, so both the number of roadkilled individuals and the number of field observations were relatively low. Nevertheless, we had the opportunity to examine how the number of individuals of the species that were killed in the traffic varied over time and within years. According to our data, more birds collided during the winter, and also between July and November. This can be explained mostly by the seasonal lack of food and the fledging time of inexperienced juveniles. The temporal distribution of field observations were different from the dynamics of the roadkills, as the species was mainly observed during the breeding season. The exact population size of the area can be difficultly estimated, as it breeds mainly in attics of stable, granary and church buildings. The breeding population of Kevermes was estimated at 3–4 pairs and did not change significantly in the studied period. Over the same 28-year period, using the same methods to the two other most common nesting owl species of the region, we found that the within-year roadkill dynamics of the Little Owl (Athene noctua) and the Northern Long-eared Owl (Asio otus) differed from that of the Western Barn Owls, which may be due to the different feeding habits of the species. We can conclude that the number of roadkilled birds was proportional to the local population of the species.

Its European population is the strongest in the Mediterranean, but it also breeds in Central Europe. It still nests in small numbers in the Carpathian Basin, but has become extinct as a breeder in Hungary, where it was never a common species. In the present study, we summarised the occurrences of the species in the Carpathian Basin published in the literature. In the late 19 th and early 20th centuries, a large amount of observational data on the spring migration of the species was collected, which allowed us to describe the migration phenology of that time. The Common Rock Thrush bred in small numbers in mountainous areas of Hungary, in natural habitats and in mines, vineyards and orchards. The collapse of the population occurred in the 1970s, but thereafter a few pairs bred in Hungary until the 2010s. Very few published records were found in Slovakia and Romania, which does not give a true picture of its former distribution there. However, its population has also declined drastically in Romania and it has become extinct as nesting species in Slovakia. The exact cause of the decline cannot be determined and several explanations have been proposed in recent decades. It is likely that the Carpathian Basin population, which is considered to be an edge-population, has been more exposed to negative changes, such as climate change, chemical inputs or changes in wintering grounds. A century earlier, the median date of the first spring returns was mid-April, but sometimes it was observed as early as late March. Nowadays, vagrant individuals have been observed again several times in Hungary, which gives us some hope for the future.
