when you see a bird soaring through the sky. with barely any movement at all you might wonder how it got so high. and so fast and how it got off the ground. first, we will talk about their build most birds were built gracefully. and they also have hollow bones making them extremely light. now we will talk about what they have to overcome every time they take off. for starters you might have already guessed it would be gravity and another would be a drag. if you are in some sort of water source move your hand under the water really quickly. the water in front is producing drag so you cant move fast also like the bird flaps it creates thrust. which is the air going over and under the bird's wings. creating it to move forward.

so I have read this part before but I never told you about it this is quite interesting. called rooster earplugs the rooster lets out a cockle doodle do that has 140 decibels. of sound that's loud enough to defend. you that is why the rooster does it in a high place and away from the hens. so he doesn't deafen them also the rooster has these built-in earplugs that totally block up his ear ducts. also he has a lot of hair or something like that in there so it would have to get through that. see even in this stupid animal God has put in these amazing adaptions or something like that other than adaptions.
