The Slavonian Grebe is one of five grebes regularly seen in Northumberland. There is a sixth (the Pied-billed Grebe) but that is very rare indeed. In its summer plumage, the Slavonian Grebe is quite spectacular, with a black head and a large wedge of golden feathers sweeping back behind its eyes. In its winter plumage it is relatively plain, being just black and white, although it still has piercing red eyes. This one is a moulting from winter to summer, so is a bit on the messy side.
