On 26 September 2013, on the Wadden Sea Island of Schiermonnikoog, a resting (presumably male) Peregrine Falcon was recorded that approached a Kestrel in low-­level flight across a distance of 200-­300 m. After a short skirmish the Peregrine grabbed a prey from the air and returned to its sitting post where it seemed to devour the prey. However, when checking the site, a young Common Vole Microtus arvalis was found below the sitting post, still warm, with a small ventral wound and weighing 8.3 g. Apparently, the Peregrine had kleptoparasitized a freshly caught prey from the Kestrel.
