Firstly, they aren't true finches. They were collected by Darwin on his second voyage. The main observations are there beak shapes and sizes. Depending on their location in the islands, the finch's diets vary and then because of their varying diets they have varying beaks which have adapted to their food sources. The variances in the finches and their beaks despite all living in the same island chain spurred Darwin's theory of evolution.
Since Darwin's time there have been many expeditions to the Galapagos Islands and new discoveries have been made such as the Large Cactus Finch males have two different beak types. Those with the shorter beaks have one distinct song and those with longer beaks have a different distinct song. They both feed on the same type of cacti, but in different ways due to their beak types. It's thought it's so the birds can all still feed when the food is scarce.

Who discovered Galapagos Island?
Charles Darwin made observations on the galapagos islands
Why and what made the Grant's want to study the finches in the Galapagos?
The Grant's lived on an island and started to want to study the finches in the Galapagos. They thought they were very interesting animals and wanted to know more.

On the voyage on the Beagle Charles Darwin made many observations of what?
On the galapagos island
What did the variation in the Galapagos finches seem to be well-suited to?
The variations in the Galapagos finches made them well-suited to different types of food.each finch had its own adaption per island on an island where there were only had berry's they hard short strong beaks on islands where mostly flowers bloomed the beaks were long and narrow so they could eat pollen
When during the voyage on the beagle where did Charles Darwin make many of his observations?
The bulk of Charles Darwin's observations were made on the Galapagos Islands. He had journeyed there seeking evidence that wildlife was connected to a much older center of creation. His studies of different variations of finches there, led to his Theory of Evolution.
What island group off the coast of South America was made famous by Charles Darwin?
Galapagos island was made famous by Charles Darwin because of the discovery of the Galapagos tortoise.
What are the Galapagos Island famous for?
Galapagos islands are famous for the Darvin's finches (which give evidences for the evolution of organisms mainly Darvin's theory of natural selection and survival of the fittest)Darvin, the naturalist, who made the Galapagos islands famous ...........in the world.
What unusual information did Darwin collect about the Galapagos finches?
Every type of bird was a finch, but the genetics of each bird varied upon which island he was on. So he made the theory of evolution explaining how the original finches evolved into having different beaks, colors, eyes, and sizes. Again each of those varied depending on the island.
What evidence of evolution did darwin present to the world?
Charles Darwin visited Galapagos Island during his famous voyage around the world. He did research on finches and the Galapagos Giant Tortoises during his stay there. He found that these animals have developed themselves according to their habitat. The tortoises living in the surroundings where food was available at low height had round carapace while those who lived in the surroundings where food available at high height had saddle back carapace. Similar with the finches, It was sound that there was difference in the same species of animals at all the seven islands at Galapagos. This observations made by Charles Darwin lead him to came up with the Theory of evolution.
