This video from the Galapagos is called Blue-Footed Booby Mating Dance.
From the Seattle Post-Intelligencer in the USA:
Birders are flocking to Skagit County, where a blue-footed booby was reportedly sighted — and photographed — in recent days.
It was the first sighting in Washington state since 1935 for a species native to the west coast of Mexico and the Galapagos Islands.
“The photos are pretty conclusive,” said Bill Tweit, fishery manager for the Washington Department of Fish and Wildlife.
“Anglers fishing between Anacortes and the San Juan Islands should keep an eye out for a goose-size seabird. … It’s an immature bird, so its feet are white rather than blue.”
