The wildlife photographer who took a photo of a bird passing a cigarette to its chick shared it with an urgent message.
“If you smoke, please don’t leave your butts behind,” Karen Mason wrote on Facebook.
The picture of the black skimmer bird feeding its chick a cigarette filter was taken on a Florida beach in the United States.
It has drawn an emotional response from many.
In another photo, the chick is seen carrying the cigarette filter in its mouth.

Ms Mason said both photos were captured at St Pete Beach, on Florida's mid-west coast.
“This skimmer chick was offered a cigarette butt by it’s parent,” Ms Mason said.
“It’s time we cleaned up our beaches and stopped treating them like one giant ashtray.”
Many on social media labelled the scene a distressing sight.

"If you smoke, please don't leave your butts behind - birds can mistake the filters for food."
Cigarette butts are the most commonly discarded piece of waste globally, according to the World Health Organisation.
There are around 6 trillion cigarettes manufactured annually.
In Australia, close to seven billion cigarette buds are discarded each year, again making them the most littered item, according to Waste Management Australia.
The butts are made up of a type of plastic fibres (cellulose acetate) and can take years to break down.
