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.

What observations did Darwin make about finches in the Galapagos island?
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
What observations did Charles Darwin make about finches in Galapagos island?

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 island did Charles Darwin make his most important observations?
Charles Darwin made his most important observations on the Galapagos Islands, specifically on islands such as Santiago, Santa Cruz, and Isabela. These observations influenced his theory of evolution by natural selection.
Who discovered Galapagos Island?
Charles Darwin made observations on the galapagos islands
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
Describe the observations that Darwin made about the species on the Galapagos island?
During his visit to the Galapagos Islands, Charles Darwin observed distinct variations in species, particularly among finches and tortoises, that seemed closely related yet adapted to different environments on the islands. He noted differences in beak shapes among the finches, which correlated with their specific diets and the types of food available on each island. Additionally, the tortoises exhibited variations in shell shape depending on the vegetation of their respective islands. These observations contributed to his formulation of the theory of natural selection, illustrating how species adapt over time to their unique habitats.
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 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.
