Those members which have beaks that will allow them to eat worms found in deep earth easily will be better adapted and thus their population will be more fit.

Now what do you think? What kinds of beak will be more helpful if someone wants to eat something found in deep earth? 

Longer beaks? or wider beaks? or brighter beaks?
