Most likely because they are the color purple.
The females and immature males are dull brown with dark-brown streaks, but the mature males have a purple "cape" over their head, throat, and the upper part of their backs. So, yes, you can see purple finches that are not purple. Male purple finches are more of a rosy,red color, with a white belly.They have been described as a sparrow dipped in raspberry juice.
Charles Darwin discover the finches in Galapagos in 1831. He noticed that the finches beaks were different compared to the finch's in Ecuador.
All known species of Darwin's Finches are found on the Galápagos islands. With the exception of one, the Cocos Finch, which is found on the Cocos Island. Darwin's finches are not actually true finches. Darwin knew they weren't finches, but an ornithologist called Percy Lowe, later in 1936 incorrectly called them "Darwin's Finches" in a book, a term which unfortunately stuck.
Spring, they move north, leaving the wintering grounds by April. They began the southward movement by late September.
Well.. from my experiences with finches - they like holly tree's, and rhododendrons.
Peter and Rosemary Grant chose to study the Finches in the Galapagos because they were hybrid.
baby purple finches look like fluffy clouds with beaks
yes
That would be a charm of finches.
No. They are seed eaters, and great song birds. Perfectly harmless.
Different finches like different seed. Thistle attractspine siskins and goldfinches, and sunflower attracts goldfinches, pine siskins, purple finches, house finches, and other birds like nuthatches, cardinals, titmice, chickadees, grosbeaks.

Male finches are called cocks

The evolution of numerous species, such as Darwin's finches from a single ancestor is called adaptive radiation.
