For it shall be that, as wandering birds, As a scattered nest, So shall the daughters of Moab be At the fords of Arnon.
Ibn Ezra on Isaiah

Rashi on Isaiah
driven from the nest like young birds driven from their nest, who roam and wander, so shall the villages of Moab wander to the fords of the Arnon.
