“The dashing Horned Grebe is a sight in summer with its gray-black head and back, brick red neck, and blazing yellow-orange “horns” on its head. Look for these small grebes on migration as they travel to their breeding lakes in the far north. In winter, they transition to a much more subdued gray and white, with a neat black cap and white cheek that helps separate them from the similar Eared Grebe. In winter, Horned Grebes gather in flocks and dive for fish and other small prey in lakes and bays.”
