Please don't feed the PELICANS!
It's obvious that some people have been feeding the pelicans up on the deck of the pier at the cleaning station. All that does is to attract more pelicans (pelican-poop) to the fish cleaning station, which is essentially a food processing area. There are signs at that location for that reason.
Some people may ask - "What's the difference between feeding them on the pier and feeding them (by throwing the carcasses over the rail) as they gather in the water below the cleaning station?" The answer lies in -- where the poop goes. When they're in the water, they poop in the water. That's where it belongs and where it would go, naturally, not on the cleaning table!
