(Leucistic) whitecheeked honeyeater

Caught this one


and it should look like this

Nice shots

What's the reason for the different look ?

I looked up the big word in brackets - whiteness caused by an overall lack of pigments. I'm guessing that its parents both had the same recessive gene for it?
Super sharp images and educational too - can't be bad

Thanks David for the explanation, also note the eyes and legs dont change colour as in albinism, piebald is also a form of leucism.
Hope that helps you out Stuey?
