Weight and lift are two forces that affect a bird's flight. Two other forces are drag and thrust.
Wings and feathers
Birds use the four forces of flight kind of like an airplane does. Lift pulls them up and weight pulls them down. Thrust pulls them up and drag pulls them down.

To overcome drag. The four forces always acting on an airplane in flight are: Lift, thrust, gravity, and drag.
drag
The drag is caused by friction with the air or water.
Birds are groups of animals equipped for flight.
To stabilize their flight.
Drag- APEX :)
the four forces of flight are lift,drag,weight/gravity and thrust.I have no clue how to describe them.........i hope that helps!
