This is the rainbow finch.

The Gouldian finch (Chloebia gouldiae), also known as the Lady Gouldian finch, Gould’s finch or the rainbow finch, is a colorful bird species that belongs to the Passeriformes order. It is an exclusive bird species of Australia.

The Gouldian finch is famous and prized primarily for its spectacular plumage. Interestingly, both male and female birds are all brightly colored, while it’s only male birds in many other species.

As their name suggests, rainbow finches can be of any color like a rainbow. They appear naturally in red, blue, green, yellow, etc. Additionally, selective breeding can create some striking color mutations such as “dilute” and silver, diversifying the appearance of these birds.

A rainbow finch is typically measured at 4.7 – 5.9 inches in length and 0.49 – 0.53 oz in weight. The fact that they are small birds can not prevent them from winning the spotlight. The Gouldian finches existing in the wild normally have a red, yellow or black head; and these birds are commonly differentiated in name by this feature. In their native habitat, most of the Gouldian finches have a black head. The number of birds has a red head is quite small and even smaller with orange head, about 1% only.
