Eared Grebe - Podiceps nigricollisEared Grebes are a fairly common grebe in the state, more so than the similar Horned Grebe.  They are a very gregarious bird, often breeding in very large colonies, and often migrating together in huge flocks.  The "ear" of the Eared Grebe is a tuft of gold feathers behind the eye that appears during breeding season (see bottom photo).  The photo on the right is of a bird in breeding plumage.  Neck color is a distinguishing mark used to differentiate summer plumage Eared Grebes and Horned Grebes.
