Sun is coming out. We may get some brood yet. Male NBG showing spots on nape typical of nesting males of the subspecies. The female HpBG I think most likely to spawn is constantly barred which differs from NBG and all CNBG I have seen. The HpBG's also a red tint that sets them apart from the other subspecies. Final difference is vertical fin color, NBG is aquamarine while HpBG is gray. If CNBG's were present, then they would be yellowish to red with white trim.
