it depends on which way the sun rises and sets in the morning and evening.
you do this because it makes life easier for birds to raise their chicks and keeps them warm.
No. They can only travel in one direction. If a bird overshoots its nest,
it has to go around again and try to hit it on the next pass.
parrot,owl
beacause
Hummingbirds feed on the nectar of flowers so they fly forward and backward to insert (then extract) their long beaks, without landing on the flowers.
There is no such thing as a dinosaur that flys. The difference between a pteradoctyl and a bird is: Birds have feathers and pteradoctyl's don't. The difference between a oviraptor and a bird is: Oviraptor have hands and birds have wings.
Birds fly, fish swim
No,not all birds that have wings and feathers can fly. An ostrich & peacock can't fly and they both have feathers and wings. Birds like the ones I named have small wings that's why they can't fly. All their muscles are in their legs.
When birds fly south for winter each year, this is known as "migration." The birds fly south to live in a warmer climate, and in the spring they fly north again when the weather changes.
Yes.

Because the longer side of the "V" has more birds.
yes!
It is not only birds that fly. Bats fly and they are not birds.
Most birds can fly. Not all.
To say that birds use wings and feathers to fly, so all birds can fly, would be false. Not all birds can fly. An ostrich is an example of a bird that cannot fly.
The birds that can fly because it is easier for them to find food.
all birds fly xept penguins
No such thing, lol
