Which outcome limits migration distances for birds dependent on soaring?

💡 Explanation

Birds need consistent thermals to cross vast distances; thermal lift relies on differential heating of air masses. Insufficient thermal updraft availability reduces their aerodynamic soaring capacity because reduced atmospheric convection decreases buoyant force, therefore limiting travel distance rather than predator impact or communication.
