11.10.2026 / Sunday / 12.00–13.30 Park Dolinka Służewska / meeting in the park behind SDK / free admission Jackdaws, unlike most corvids, are cavity nesters. They nest in natural tree hollows, crevices in buildings, chimneys and specially prepared nest boxes. During the walk we will see such boxes and take a closer look at the jackdaws living in Dolinka. We will learn about their habits and find out how their numbers change throughout the year. Co-organizer: Warszawska Grupa OTOP.
