1 Answer

Answer :

(3) Birds Explanation: Darwin's finches are a group of about 15 species of passerine birds. They often are classified as the subfamily Geospizinae or tribe Geospizini. They were first collected by Charles Darwin on the Galapagos Islands during the second voyage of the Beagle. All are found only on the Galapagos Islands. The birds vary in size from 10 to 20 cm and weigh between 8 and 38 grams. The smallest are the warbler-finches and the largest is the Vegetarian Finch. The most important differences between species are in the size and shape of their beaks, and the beaks are highly adapted to different food sources. The birds are all dull-coloured.
