• The geographic distribution of the Long-legged Buzzard ( Buteo rufinus ) in Europe has expanded during the last decades. The aim of our study is to (1) gather a comprehensive dataset regarding the presence of the Long-legged Buzzard in Romania, including all the available historical (i.e., before the year 2000) and recent observations (i.e., between 2001-2023), to (2) map Long-legged Buzzards' observations, and to (3) show the occurrences of the species according to phenological periods of the year, in the different regions of Romania. Historical occurrence data are available from 1891. Using this data, we mapped the distribution of the Long-legged Buzzards between 1891 and 2000, and found that the species was present during this period in the similar regions of Romania as the ones from where recent observations were undertaken, i.e., between 2001 to 2023. However, after the year 2000 considerably more observations are available, indicating a potential expansion of the species and/or an increased sampling effort. Furthermore, contrary to the previous assumptions, our data revealed that the species is present in recent time in each phenological period of the year, that is, pre-breeding, breeding, post-breeding, wintering, in all regions. Overall, our comprehensive dataset may be the foundation of future works aiming to reveal details about the potential expansion rate, and the temporal and spatial distributions of the species over the last century.
