And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

A female falcon was equipped with a satellite tracking system in South Africa before migrating to Finland. Image shows tracker data. In just 42 days, she flew over 10.000 km, at an incredible average of 230 km per day and nearly in a straight line.
That's an average of 6mph. So that's flying maybe 8 hours per day. The only incredible thing is reliably finding food over such a wide range of ecosystems.
You're right. And 17.9 mph is probably a realistic cruising speed. Point is, if you work hard at something nonstop for 42 days, you'll probably get there -- if you have enough food.
These migrating birds are amazing. They possess built in navigation systems that can sense direction like a built in compass, detect magnetic fields, and possess vision so acute that we cannot comprehend it. Their bodies are the epitome of aerodynamic perfection and all the aircraft that man has produced are just crude copies of the magnificent, God designed structure of these CREATED, not evolved, creatures.
Incredible, and very cool!
ReplyDeleteI bet a lot of people wish they could fly out of S Africa now.

ReplyDeleteKill joy
ReplyDeleteWith or without a coconut?
ReplyDeleteThe Winner !!!
DeleteThat would be 5.9 mph if the bird flew 24 hours per day. If it flew 8 hours per day the average speed would be 17.9 mph.

DeleteHawks and falcons are masters at riding thermals to gain altitude, then gliding long distances.

ReplyDeleteNot straight line if you take a 3-d view.
