Blue...m/f? Definitely a rooster and the only I'm sure of the sex....but color? Mainly buff, with silver 'undercoat' and tips of wings, tail. Another....nearly the same color, but the buff and silver are both lighter, and head feathers seem to be coming in silver. Biggest mystery, colorwise, and I think hen. The brownish tint on her back is actually nearly red, in spots seems nearly striped, like a cuckoo but much lighter. So pretty, even with the crossbeak. Also have never seen this color before....mainly black with neon green tips....oh, wait...that's just paint. But....hen?
