Loons are famous for their hauntingly eerie call. The sexes have similar plumage, but the males are larger than the females. They are similar to cormorants and penguins. All of these birds have webbed feet, float low in the water, and chase fish by swimming underwater. The fact that a loon often abruptly dives for fish resulted in the birds being referred to as divers in the Old World. To aid their swimming and diving, their legs are located far back on their body. This results in their having great difficulty walking and this clumsy behavior resulted in the birds being termed loons in the New World. Grebes also have their legs located far back on their body and they too walk ungainly.
