The cause of death of a little penguin washed up at Manly Cove is yet to be determined.Manly resident Angela Van Boxtel said she found the dead penguin on Saturday morning.
“It was so sad because just earlier, I had been at the wharf watching a little penguin swimming around,” Ms Van Boxtel said.
“I’m worried this dead penguin was the same one.
“When I spoke to the penguin wardens, they were concerned it could be part of a breeding pair.”
Ms Van Boxtel handed the penguin over to Manly Sea Life Sanctuary and it had no obvious injuries.
“My concern is that it swallowed a piece of plastic,” she said.
“There’s more and more plastic in Manly every year. It’s on the sand and floating in the water, it's disgusting.”
A Manly Sea Life Sanctuary spokeswoman confirmed the little penguin was brought in to the sanctuary.
“The little penguin was then transferred to Taronga Wildlife Hospital where a necropsy will be performed. The results will be released by National Parks.”
