The birds were not ID'd during the show, I'm not sure about this one. Saker falcon is the closest I could find from species listed for Pairi Daiza, but it also does not completely seem to fit. Can anyone confirm or correct?
@amur leopard To me when checking images the lanners seem to have more pronounced stripes and a reddish area on the head, while the sakers look more like this bird.
Saker, or less likely, hybrid of saker x prairie or saker x gyrfalcon, but with strong saker blood in it anyway.
Lanners are completely different from sakers. A lanner looks like just a peregrine falcon with a reddish cap.
