During a waterbird count in one of the lakes bordering Flevoland (Ketelmeer) on 10 November 2004, an immature White-tailed Eagle (2nd or 3rd calender-year) was seen in full pursuit of a juvenile male Northern Goshawk; the latter carrying a prey (possibly a Coot Fulica atra). The flight of the eagle was dexterous and fast; the bird easily outmaneuvered the Goshawk for 3-4 minutes, even being able of gaining height and momentum to dive-bomb. Eventually, the Goshawk dropped its prey, which was retrieved by the eagle from the water with a single swoop. During plucking, it was noticed that the eagle carried a red ring on its right leg, but it was impossible to see whether it was coded or not.
