Kleptoparasitisme en verstoppen van prooien door roofvogels

A case of kleptoparasitism between Eurasian Kestrel Falco tinnunculus and Eurasian Hobby F. subbuteo was recorded near Sohar in northern Oman on 28 October 2000. The Hobby captured a prey and was immediately pestered by a Kestrel. The Hobby disappeared in a shed, followed by the Kestrel; some time later the Hobby reemerged without prey, apparently leaving the Kestrel (and the prey) behind. Another instance involved a Eurasian Sparrowhawk Accipter nisus robbing a young Kestrel off its vole in Meijendel in The Netherlands. Caching by an adult Kestrel was witnessed in the evening twilight in Friesland; the first catch of a vole was hidden in a ditch, after which hunting was resumed. The second catch, shortly afterwards, was eaten right away.
