Barn Owl vs Peregrine Falcon vs Greylag Goose | Super Powered Owls | BBC

what does it take for Lily to get airborne to find out lloyd and Rose have enlisted the help of bird expert Professor Graham Martin and high-speed cameraman mark Payne Gil for a bird to take to the air it has to overcome two forces gravity the invisible pole that keeps us grounded and drag which is the resistance we experience as we move through the air birds use their wings to create lift and thrust but how do they do it birds wings are the shape of an airfoil air traveling over the top of the wing has to travel faster than air traveling beneath this creates a difference in air pressure which generates lift to gain forward momentum birds flap their wings this makes the air flowing over them spiral off the trailing edge these vortices thrust the bird forwards and upwards these are the basic principles of all flight but what's so unique about the white owls fly we fight quite a few different types of bird varying sizes yeah but the one thing I notice about the Owls is they always appear to be a lot slower than their lines from the other birds well all birds got different wing shapes and they can fly at different speeds it's just like aircraft so if you look at the wing size of a barn owl it's actually got a very big wing and so they can fly very slow very controlled to really understand the Barnell slow flight Lloyd's putting Lily to the test against two of his other birds mazie the greylag goose a long-distance endurance flyer and moses the peregrine falcon one of the fastest birds on earth the Peregrine takes the lead it's long and pointed wings are quite flag designed for speed and maneuverability which it needs to hunt the goose is next weighing three kilograms it's relatively short and narrow wings work hard to get it airborne the bar now has the largest wings in relation to its body and its airfoil is very curved which generates a huge amount of lift so the barn owl can fly slower and with fewer wing beats than most other birds you
