Darwin's Finches

The finches on the islands were different. Their beaks had different shapes. Beak shape was an adaptation. It helped the different finches get their food.

For example:

Green warbler‑finches have thin, sharp beaks. They use them to spear insects.


Medium ground finches have short, stubby beaks. They use them to eat seeds on the ground.


Common cactus finches have broad, curved beaks. They use them to nibble on plants.
