So in this question we'll be talking about flight adaptations in birds.
00:14
Now over the aeons, birds have evolved not only wings but many other adaptations.
00:27
Not only wings, but many other adaptations, such as flight muscles.
00:55
They have well -developed muscles that control the action of flight muscle and muscles are stated and large, and strong on wings.
01:30
So they helps in taking them a flight.
01:37
The second adaptation will be talking about that they have pneumatic or hollow bones.
01:46
They have pneumatic or hollow bones, which makes them lighter to decrease buoyancy and make diving easier.
02:23
Make diving easier.
02:29
The next adaptation we'll be talking about is their avian integuments.
02:38
Avian integuments is thin, elastic and loosely attached to the body, loosely attached to the body, which gives them freedom of movement, which gives them freedom of movement and and the digestive system is also adapted for flight because they have very high rate of metabolism.
03:52
Very high rate of metabolism, which means they are making greater energy.
04:06
Rectum is very small.
04:11
Rectum is very small because of the very low or because of low or because of low or minimum undigested waste, low undigested waste...
