What might happen over time if two bird species competed for the same seed resource and one preferred larger seeds while the other species preferred smaller ones?

Question

Over time, the bird species with beaks better adapted to collecting the larger seeds will be more successful at reproducing, passing down their genetic advantage for larger beaks to their offspring. Similarly, the bird species with beaks better adapted to collecting smaller seeds will also pass down their genetic advantage to their offspring. This can lead to a shift in beak sizes in each species, as they adapt to their preferred seed size. Eventually, this can result in the two species occupying different niches, where they do not compete as directly for the same resources.
