What are some ways that mammals differ from birds?
To start off, birds flap their wings to propel themselves forward whereas airplanes propel themselves forward using a propeller that spins around. Airplanes use wires (both electrical and cables) to maneuver. Birds twist their wings to maneuver. Airplanes also have lights to show their orientation and location. Birds on the other hand have no lights because they really don't need them! Airplanes are made out of metal which doesn't repair itself it it gets broken or injured like a bird does. Airplanes need aviation fuel to run where birds just get their energy from seeds, bugs..etc. hope that helped
