Darwin Finches facts

While investigating facts about Darwin's Finches and Darwin's Finches Video, I found out little known, but curios details like:

Darwin's finches, a classic example of evolution, are being rapidly killed due to an infectious parasite that damages their beaks, preventing them from producing mating calls and as a result, reproducing. The larvae also infest the nests and feed on the blood and tissue of the nestlings.

how and why species multiply the radiation of darwin's finches?

Darwin's Finches, a small group of Finches that were blown onto the Galapagos Islands by a big storm. They found themselves with an abundance of food & no predator's, hence reproducing rapidly causing food supplies to dwindle. The population was threatened, until natural selection intervened.

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across. Here are 11 of the best facts about Darwin Finches I managed to collect.

1. Darwin proposed its well known theory of evolution by watching and examining finches on Galapagos Islands. 14 species of Galapagos finches have common ancestor that has arrived on Galapagos million years ago. One type of finch evolved into 14 different types of birds as a result of adaptation to different types of food and habitats (all 14 species of Galapagos finches inhabit different types of habitats/islands). 14 species of Galapagos finches differ in shape and size of their beak, body size and behavior.

2. The 13 species of finches on the Galapagos Islands are often referred to as Darwin's finches.

3. Darwin’s Finches are being attached by maggots and larger fly larvae that take up temporary residence in a chick’s nostril and dine until morning where they then squirm back into the entwined twigs where they wait until night comes again.

4. Charles Darwin's finches are a historical myth. Darwin didn't even know they were finches, and never mentioned them in Origin of the Species.

5. The Vampire Ground Finch, a bird found in the Galapagos that drinks the blood of boobies (also bird) that occupy its island. It's also one of Darwin's finches.

6. Darwin didn't actually notice the differences between the finches (he did notice other things) until he got back to England where an ornithologist at a museum to which he gave things he got from the Galápagos noticed them.

7. The Vampire Finch - one of Darwin’s Finches with the largest and most pointed beak. It’s name is derived from its habit of occasionally drinking blood from another bird — the blue footed booby.

8. Darwin's theory was NOT initially based on Galapagos finches, but mockingbirds

9. The finches on the Galapagos Islands (Discovered by Charles Darwin in the 1830's) are suffering from a parasitic fly introduced to the islands by humans.
