Because they eat different stuff. Just like rabbits and cats have different teeth.
Charles Darwin observed various species of finches in the Galapagos Islands, particularly the different beak shapes that correlated with specific food types. One such observation was the finches' beak adaptations to different diets, such as the ground finch whose larger beak was suited for cracking seeds, while the tree finch had a thinner beak for catching insects.
do all finches have the same beak.
The shape of a finch's beak is different according to what food it eats.
adaption of the finches to different environment
natural selection
Darwin observed that the finches on the Galapagos Islands had unique beak shapes and sizes that were adaptations to different diets. These variations in beak structure led him to hypothesize that the finches had evolved into different species to better exploit available food sources on the different islands.
The shape of the Galapagos finches' beaks is adapted to the type of food available in their environment. Different beak shapes allow the finches to efficiently exploit different food sources such as seeds, insects, or cactus flowers. This adaptation helps the finches survive and thrive in their specific habitat.
he saw that in the different places and things the finches ate made their beak a different size and shape to adapt to their surroundings

He realized the the finches had been able to adapt to their natural surroundings to survive.
Finches developed many different adaptations. For example, one type of finch had a short strong beak meant for cracking seeds, while another had a long narrow beak for gathering food from the inside of flowers, and cacti, therefore making each species more adapted to its specific environment and more able to gather food then they would on another island with a different main food source.
