The most probable explanation for the observed decline in small-beaked finches and the increase in large-beaked finches is:
**Available food changed and the small-beaked birds could not readily adapt.**
This response suggests that a change in the food supply favored larger beaks, likely because larger seeds became more prevalent or accessible, while the small-beaked birds were unable to adapt to the new conditions and thus declined in number.
