Article summary

In 2013 the postbreeding passage of Honey Buzzards in Wallonia has reached a magnitude rarely seen before. While the passage usually occurs in the east of Wallonia, observers at sites across the region reported passages of hundreds of birds in just a few hours. There were also large groups that crossed Flanders; again a most unusual event.
