Birds are perhaps the most colorful group of animals, bringing a splash of color to the natural world around us every day.

And as far as we know, blue feathers have been fairly uncommon through time: Of the 61 lineages of living birds, only 10 have species with E. brachyptera ’s most probable coloration.

Blue bird can turn into 3 birds. The first thing that came to my mind when I saw this was: is each of the new birds 1/3 the mass or are all the new birds the same mass as the original.
