Pelican near Santa Cruz Island

A brown pelican skims along the glassy ocean just after dawn one morning, with the hills of Santa Cruz Island in the background.  The lack of wind in the early morning must make fish beneath the surface easier to see.  Only brown pelicans execute a wheeling turn, follwed by a vertical dive into the ocean with beak and body stretched into an arrow.  Pelicans would probably benefit from polarized sunglasses, to cut glare from the ocean surface.
