Are penguins the only bird that swim under water?

    Certainly not; dozens of kinds of birds swim underwater.

    Penguins are able to swim underwater because they possess unusual avian features like short body feathers, solid bones and relatively short, muscular wings, which in turn make them more suited to moving through water than for moving through the air.  They are not, however, the only birds with these adaptations.

    Many seabirds such as cormorants, guillemots, auks, shearwaters and diving petrels possess these same features. 

    Some birds, like the loon, use their feet to push themselves through the water, and others, like the pelican and the tern, rely on momentum generated from a high dive into the water.
