Another AQA question! Think what birds do... they Fly (1) and Eat (2)
flying and hatching eggs
eating foods
Birds have higher body temperatures then most mammals and because of this use a lot of energy. Maintaining body temperatures and flight are to things that birds do that require energy.
Birds get there energy for eating, they digest the food that gives them energy. They can fly by having hallow bones, they use there energy as efficiently as possible so they can fly for long periods of time.
Yes. They use energy extremely quickly.
Wind mills, sail boats, kites, birds.
The sun gives more energy. Absolutely. Especially because birds use energy that came from the sun and was stored in their food. All plants and animals rely on the sun for energy, either directly or indirectly.
Birds need lot of energy because flying uses a lot of energy.
Birds are endothermic. Reptiles are ectothermic and are referred to as "cold-blooded."
It depends on the owl. Most owls and birds don't think much of flying. flying isn't for fun, its for life. most birds just glide and flap their wings, but that's for hibernating and seeing other birds, getting away from predators and for food. Birds don't want to use up their energy. for example, if predators were chasing you and you try to get away, but oh no! no energy left to get away! wouldn't you wish you hadn't used up your energy earlier? flying may be exiting for us.. but to them it usual, so they don't do it for fun, but for living.
they store up on energy when their not migrating, so that they can burn off that energy so the moral is birds are extrordinary
They eat smaller birds for energy...

No
