It's so dark and gloomy outside its hard to show their true colors in pictures.
Do you have any dusky birds? I think if she was dusky you'd see it popping up in others as well, since the chocolate sure did, lol.
Lol, that's funny, silver (as in two copies of blue dilution on an extended black base) is not a new color, and that male is definitely not based on Extended black, so I have no clue what 'silver' they are referring to. I don't think that female is extended black either because I see eyestripes and I think a faint speculum. Interesting.
