In alternate plumage this striking bird's lower neck, chest, and sides are bright chestnut. Three groups of yellow plumes adorn the sides of the head. Its head and throat are black. This grebe favors areas with much open water surrounded with emergent vegetation.
The horned grebe is a rare breeder east of the Cascades. Malheur National Wildlife Reserve averages four to five pairs per summer. It is also rare along the coast in summer and is an uncommon spring and fall transient on lakes, reservoirs, and large rivers west of the Cascades and uncommon to common east of the Cascades. In winter, it is common along the coast in estuaries and near-shore ocean.
