Geoff, do you have additional photos of the White-spec?  I may be wrong but they look like different individuals.  Your bird looks more like a 'cognitus' phase individual in which the grey on the head is lacking and lateral crown stripes are not pure black.  It also looks as if the finer detail of the eye-ring and loral pattern are different.  However, given that they were in the same location, this is perhaps unlikely.
