There have been a lot of Eared Grebe reports lately in the Seattle area. I've seen a lot of molting Horned Grebes the last couple weeks.

"The two species can be tricky to separate in March and early April as they undergo molt into breeding garb. At that time blotchy plumage and irregular head shapes often cause confusion."

Bill shape seems not to change much.
