A species of birds lives in a particular niche. As their population increases, many of these birds migrate to new niches with different food sources.

In niches where hard seeds and nuts are the main food sources, the birds with stronger beaks succeed and grow in population. In niches where small insects and larvae are the main food sources, the birds with longer, narrow beaks succeed and grow in population.
