Breaking news from Chris at Where Light Meets Dark alerts us to another blue bird in Australia. This time the blue bird is an Australian white ibis, which is ordinarily white. In this case, in addition to the photographs, a blue feather has been recovered.

The other two types of blue birds were a little corellas and one or more house sparrows.

All of these have turned up blue in and around Sydney between June 2008 and June 2009.
