Sperwer Accipiter nisus zichtjager na zonsondergang
De Takkeling , Volume 26 - Issue 3 p. 201- 203
A Starling roost in the city of Breda was frequently visited by a (not necessarily the same) female Sparrowhawk between late September and mid-November 2017, until the roost was deserted following the shedding of leaves of Carpinus betula (the trees in which the roost was situated). Hunting Sparrowhawks visited the roost between 8 and 47 minutes after sunset (on average 19 min, sd=13.7, n=6). Camouflage hunting was recorded once, the Sparrowhawk weaving its way in butterfly-fashion underneath the trees, with fast ups and downs ending in a steep upward swoop into the foliage of a tree. The outcome remained unknown.
