This dominant mutation was developed around 2013 by G. Kerle in Australia. The bird in its SF form has a bright yellow face, white forehead, and seagreen body color (pictured first). It’s for this reason that SFs are sometimes called “whitecap seafoams”. The DF form, however, has a mostly lime green and light aqua body color, giving them the name “whitecap greens” (pictured second). These birds are known to be very healthy and reproduce particularly quickly thanks to the skill of their original breeders.
