This is a slow motion video from a Topvogel falconry show in Diessen, Netherlands of a Harris' hawk demonstrating its ability to navigate narrow gaps by flying between two people standing head to head (who look like two lovebirds themselves, HIYO!). Thank God that wasn't the Weasley family''s owl Errol, or those two would have probably lost their eyes. Birds: they are amazing. Except squirrels. "Squirrels aren't birds." WELL THEY HANG OUT IN TREES ENOUGH. I bet they were just misclassified. "You really are stupid, you know that?" Yes, that is probably the only thing I ever learned in school.
Keep going for the video.
Thanks to Speakton, who agrees Fox McCloud could probably fly his plane through a gap twice that tight.
