Havik Accipiter gentilis vergrijpt zich aan jonge Torenvalk Falco tinnunculus in nestkast

A male Goshawk grabbed a nestling Kestrel from a nestbox (width of entrance 20x40 cm) in the province of Friesland, and took the bird to its own nest (Photo). Two days later, both remaining Kestrel nestlings had disappeared, presumably also following Goshawk predation. Up till now. Goshawk predation of nestling raptors seemed to be focused on small raptor species with open nests only (Accipiter nisus, Falco subbuteo, F. tinnunculus), but this case illustrates that nestlings in nestboxes are not safe either.
