i think its swifts im not quite sure but i have never seen a swallow close to the floor
Swifts and swallows both migrate to sub-saharan Africa. However, swallows return earlier because the small, flying insects they eat are abundant during earlier spring. Swifts return later because they follow seasonal rains up towards their breeding grounds. However, the migration times of both birds will vary due to weather and food variability.
they can fly lol
The bird that can fly in the sky but can't walk on the ground is the swift. Swifts have very short legs and are adapted for life in the air, so they are not able to walk or stand on the ground like other birds.
They fly to Africa
Swallows.
Swallows are insectivorous feeding on the many tiny insects which fly through the atmosphere. They feed exclusively on the wing not on the ground.
Swallows eat insects. They catch them as they fly.
Helicopters fly somewhat close to the ground. They fly near the troposphere. They fly at a lower altitude than planes.
sparks fly
As long as they live/work ofcourse.
