255S is a remarkable advanced coloured bird, being all grey in the scapulars and wing-coverts as 3CY michahellis. Note the fire-patterned sub-terminal band in the third tertial and the brownish wash on the inner median and greater coverts. The bill is obviously sub-adult, the legs are rather whitish yellow and the iris is very pale as well, slightly pigmented.
