The variability of breeding densities of the Nightjar Caprimulgus europaeus in various habitats in Poland is poorly known. For this reason, an attempt was made to assess the density and abundance of this species in the active military training area Nowa Dęba (Sandomierz Basin, S Poland), dominated by dry heathlands, xerophilic grasslands, sand dunes and pine tree groves. In mid June 2019, the night count of Nightjars was performed on two transects of the total length of 24.61 km. A total of 46.5–50.5 Nightjar territories were counted, with the density of 26.3–28.5 territories per 10 km2 of the area. The size of Nightjar population at the studied site was estimated at 78–84 pairs. A comparison with the published Polish data indicates that Nightjar breeding densities recorded in this study are among the highest in the country. This study also provides evidence for the species preference for midforest open areas (burns, windbreaks, military training grounds) over forested habitats. The results indicate that ca. 0.8% of the country population of the Nightjar breeds in the study area.
