Glorious In His Coat Of Radiant Multi-Colored Plumage, Gouldian Finch Looks Like A Shiny Feathered Kaleidoscope

After mating, the female will lay a clutch of about 4-8 eggs and then brood them. Both parents will take turn to brood in the daytime, but when the night falls, the female will stay on those eggs. When the eggs hatch, both parents take care of the chicks.

Maybe you do not know that rainbow finches from Northern Australia can somehow control the gender of their youngs. The incompatibility in the gene sequences of the black and red-headed bird results in a high mortality rate of their female offspring (up to 80%).

The female bird found a way to overcome this issue by over-producing sons, the ratio can be as high as four males to one female. This incredible little bird is the first proven instance of biasing the gender of their youngs to tackle genetic weaknesses.
