I know they're both identical colors, but some people say it's just a spelling preference, and others say Grulla is feminine and Grullo is masculine. It's meant to be Grulla = female. Grullo = male. And it's pronounced Grew-ya and grew-yo.
Also, what color are Grulla foals? Silvery grulla foals are usually born a VERY light buff/cream color, and not a light gray color. There are exceptions, but in general, this is true. True silvery grullas may have blue-gray eyes according to some sources, but this is generally true only in the foal's early life.
