Boomvalken Falco subbuteo en Nijlganzen Alopochen aegyptiacus, strijdend om oud buizerdnest?

The rapidly increasing Dutch population of Egyptian Geese is known to exploit old and new raptor nests for breeding, thus often clashing with the providers and other users of these nests. Here, one such conflict is described, i.e. a pair of Eurasian Hobbies and a pair of Egyptian Geese both being interested in an old nest of a Common Buzzard situated in a poplar lane in farmland in the province of Gelderland. A series of attempts on 5 May 2003 (between 8.46 and 9.24 hrs, summer time) by the Egyptian Geese to land in the nesting tree was frustrated by the diving and calling Hobby pair, which apparently for the moment deterred the geese from inspecting the nest.
