Bird feeder ID please

The feeder is just under a foot in size and in the feeder are the remains of a fat ball. I initially thought the bird was a pidgeon (snapped by O/H) but the colours look wrong as they appear to be brown. Starlings have left here and it looks too large for a starling. Seems quite a bulky bird too. Just seed in the fat balls don't think there are any mealworm. 

Any thoughts gratefully received.
