The birds not only look like clowns, they act like them too. They're not really made for life on solid ground - they don't walk very well, and often crash land. They're not the most efficient fliers either - often having trouble taking-off from water, and needing to rapidly beat their wings to stay aloft (whereas most seabirds can soar). But, under the water they're formidable fishers, often returning to land with bunches of little fish stuffed into their bills.
