Baby Woodpecker Query

Last autumn I had what I can only describe as a baby woodpecker or mini woodpecker, it would hang upside down on the peanut feeder and make the peck peck peck sound the woodpecker makes.  However this bird was about the size of a starling, and was a pale brown, dark brown black and white, the colour on top of head was black.  Does anyone know what kind of woodpecker this may be or if it is some other bird that behaves in a similar way?

I haven't been able to match its colouring by searching the web, the wing feathers were not speckled but more like the colouring of a sparrow.
