A Kestrel pair nested in the church of Anloo in 1995, raising successfully five young (out of six). The church also accommodated at least 20 pairs of Swifts. The female Kestrel used a buttress as observation post, from which she swooped down on the entrance of a Swift nest just after arrival of an adult Swift at its nest. She grabbed into the nest and, after some struggling, took out the Swift and flew away with her prey. On 10 July, the Kestrel nest contained the remains of nine adult Swifts, probably all of them taken in the same way. Because weather conditions were perfect, it is thought that the Swifts were in good condition and could only be taken by surprise just after they had entered the entrance of their nest.
