in an upstroke the birds wings move upwards
They mimicked the flight of birds.
Bats could fly by using their wings by flapping them up and down. When they flap their wings up it is called the upstroke and when they flap it down it is called the downstroke.

To stabilize their flight.
A flight pattern is the direction of which or how a flock of birds fly.
flight refers to a group of flying birds, ie a flight of swallows
The birds quickly took flight.
The study of birds in flight helped many engineers to make wing designs of an aircraft. The aerodynamics involved in the flight of the bird impressed the engineers. Studying birds in flight hepled aircraft designers to get the Airbus A-380 airborne.
Mostly for flight.
