How can you tell the difference between a dark eyed clear, INO and double factor spangle budgie?
Here are some of the common differences between these 3 mutations with pictures to help you identify each mutation. Look at the eye color, feet color and the color of a mature males cere for the best indications of which mutation your budgie is.
Dark Eyed Clears, INOs and double factor spangles generally have different colored eyes.
Dark eyed clears will have all black eyes with no iris rings. INOs will have red or ruby eyes with white iris rings, and with a double factor spangle you will expect black eyes with a white iris at maturity.
The only exception to this rule is if the ino or double factor spangle is either masking or split for recessive pied, which can cause the loss of the iris rings. Here are some examples of dark eyed clear, INO and double factor spangle eye colors:
Black With No Iris
Red/Ruby With White Iris
Black With White Iris
Dark eyed clears should have light pink legs and feet., as do INOs.Double factor spangles on the other hand often have a mottled mix of colors including pink, grey and blue
There are some budgies who are masking another mutation, or who are poorly marked which do not hold to these to averages however. Make sure to look at the other details in addition when trying to determining the real mutation.
In adult males, double factor spangles stand out unless another mutation effects it. A male double factor spangle will have a normal deep blue cere at maturity, where as both male dark eyed clears and INOs will have a deep pink/purple at maturity.
Exception: When a double factor spangle is masking recessive pied or fallow, an adult male will have a pink/purple cere rather than blue.
