Opmerkelijk gedrag van Wespendieven Pernis apivorus
De Takkeling , Volume 5 - Issue 2 p. 5- 6
On 1 June 1996, two Honey Buzzards cruised low over woodland, during which the second bird (presumably the male) several times stooped at the first bird, resembling the display of Marsh Harriers Circus aeruginosus. Shortly afterwards, the female re-appeared and leisurely circled the reedbeds at a height of 5 m. Two days later, the nest was located close to this site; it was already profusely lined with green leaves. Egg-laying started on 4 June. Hovering Honey Buzzards were seen twice at low heights, with hanging tail and shallow, weak wingbeats, both times followed by a shallow dive. The wings were not raised, giving a completely different impression than the well-known wing-clapping behaviour.
