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.
Birds need lot of energy because flying uses a lot of energy.
they store up on energy when their not migrating, so that they can burn off that energy so the moral is birds are extrordinary
Birds need a lot of energy because they have high metabolic rates and require energy to sustain their constant physical activity, maintain body temperature, and power their efficient respiratory system for flight. Additionally, the lightweight nature of their bodies means they need to constantly expend energy to stay airborne.
They eat smaller birds for energy...
No
Birds need a lot of food for energy.
Living things including birds get energy from food and water.
probably do to alot of flying
worms
If birds are going to fly for long periods of time to distant locations during migration, then they will burn a lot of energy.
worms and caterpillars get their energy from eating plants (leafs or other fruits and veggies). This is because plants get their energy from the sun. So, when worms and caterpillars eat this they also get energy.
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.
