The correct answer to this would be:
“inability of many medium ground finches to feed on large,
hard seeds”
The medium ground finches feed on seeds. However, the birds
have two variations in the bill shape: some birds have wide, deep bills while others
have thinner bills. The large-billed birds feed more proficiently on large,
hard seeds, while the smaller billed birds feed more proficiently on small,
soft seeds. The reduction in number started in 1977, when a drought period
altered vegetation on the island. Due to this event, the number of seeds
declined dramatically; the decline in small, soft seeds was larger than the
decline in large, hard seeds. The large-billed birds were able to endure better
than the small-billed birds thus resulting in decline in number.
I think the answer is: orogenisis
