Red Bird Feathers

Very interesting, thanks.This gets me to think of African Grey parrots. I love those as mine seems to be more intelligent than a lot of humans I've met.The "popular for humans" species have red tails (both male and female) and other species have grey tails (the not-so-popular species). As far as I've read, nobody has ever been able to get the species with the red tails to interbreed with any of the grey tail species. They don't really like each other. Wonder if anyone has ever sequenced those different DNA's.At least now we are starting to figure out where the red feathers come from around where the bony tails used to be.Edited by Pressie, : No reason given.Edited by Pressie, : I wrote tails as "tales". Duh!
