High-diving seabirds known as blue-footed boobies have suddenly expanded their range.

The Arizona Daily Star says a blue-footed booby appeared at Patagonia Lake State Park last month in the first documented sighting of the species in southeast Arizona.

Normally, the birds are found in California but no further north than the Salton Sea. Lately though, the birds have been seen as far north as the San Francisco Bay Area.
