Just Bola then KO with fists or arrows. They eat meat and they also tame very quickly but their torpor drain is quick too, so have a few narcotics or narcoberries at hand to force feed it! Also make sure there are no other dimorphs nearby because they will kill you. These fellas are good for attacking all sorts of Dino's since they are small, fast, have good attack and are hard to hit.
There is one way to knockout and take this flying menace: slingshots. Before you start hunting this dino down, practice your aim. Clubs also work, but it proves a quite difficult weapon on this dinosaur.
