After part of the iconic Santa Cruz Wharf collapsed into the ocean amid powerful waves on Monday, feathered culprits have been found to factor into the pier’s damage: seagulls.

A part of the Santa Cruz Wharf collapsed Monday afternoon during a high-surf warning, with authorities confirming two people had to be pulled from the water.

Three people were rescued from the wharf. The powerful surf also fatally trapped a man under debris on a beach in Santa Cruz, the authorities said.
