The Western Grebe has a wide range of courtship displays, as simple as head bobbing, and as complex as
the famous water-walking "rush". These birds, and the closely-related Clark's Grebe, were on show in late spring
of 2014 at the Bear River Migratory Bird Refuge in northern Utah. Western Grebes have their red eyes surrounded by black, Clark's by white. Western Grebes also have a more delicate and slightly upturned bill. Both species (they were the same species until the 1980s) are represented in this video.
