Bruine Kiekendieven Circus aeruginosus nemen douche

After a spell of rainfall (8 mm in 1 hr) on 21 August 2004, 4 juvenile Marsh Harriers were observed sitting in a stubble field, head turned into the wind and wing- spreading for at least half the observation period. Wings were stretched over the back, interspersed with preening and tail spreading. The 4 birds took flight 21 times, totaling 3.50 min (in 15 min). Some agonistic behaviour was noticed (approach with outstretched talons) but nevertheless most birds stayed within 5 meter of one another.
