Budgerigar Colours and Mutations​

The Budgerigar once called the undulated parakeet was only available in the one colour combination of green, yellow and black.

Now we have vibrant colours, pattern combinations and varieties that have transformed the wild budgerigar into budgerigars of outstanding beauty, they are easy to manage, will breed in most conditions and make wonderful pets.

The Budgerigar has been known by several names which include the Undulated Parakeet, Grass Parakeet and Zebra Parrot. The name Budgerigar means "good food", the Australian aboriginal translation for good was "boodgeree" and the end part "gai"meant food or to eat.

These birds were introduced to England in 1840 By John Gould an English ornithhologist and today's English budgerigars originated from these first imports.

Budgerigar Colours and Mutations in easy stages.

This is the easy part because we have only two colours in budgerigars,green ones and blue ones.

This is true as they are refered to as blues series or green series birds.

Start removing,seperating or adding the two colours blue and green and this allows other colours to appear.

All budgies fall into one of two basic varieties. Either they have a yellow pigment or they lack a yellow pigment base and are therefore white based.Normally this is easy to tell because the base colour is visible in the mask and between the head and wing markings.(Except the yellow faces).

Light Green



Picture is courtesy of Shobi

LIGHT GREEN - Body colour..bright grass green-cheek patches violet-spots black-eyes black with white iris-tail dark blue - legs and feet blue/grey mottled.

Green is dominant to blue and no other budgie can carry green in a hidden form,the greens can carry many hidden colours.

If we now take the yellow away from green that leaves us blue. In white-based budgies there is no yellow base pigment,so the blue structure of he body feathers results in bright blue coloration.

The Blues



Thanks Corina for the use of your picture

SKY BLUE - body colour deep sky blue - cheek patch violet - eyes black with white iris ring - tail dark blue - legs and feet blue/grey mottled - spots black.

Blue is recessive to green and can be carried in a split form in a green series bird.

The Dark Factor.

With each colour and variety of budgerigar there are three shades,light medium and dark,each

controlled by the dark factor.

This is not a colour but a genetic factor which changes the depth of shade of each colour series.
