I know there are lots of people that like to feed birds. They save old bread and give it to pigeons or ducks, and we have a bird feeder for lorikeets in our backyard.
Some people take a different approach. They favour feeding seagulls with McDonalds scraps. Their method is to eat their dinner in a car park by the water, then toss what's left out the window. The birds pick through the wrappings pecking off what they can, and then the rubbish is left behind to blow into the harbour.
An alternative method is to have a "picnic in the park", and then leave the rubbish behind. I've circled a neat pile of it in the middle of this sports oval - that would have been a feed for 3 or 4 people. Note the proximity to the rubbish bins.
I figure this is usually done by teenagers or young adults who have always had mummy around to pick up after them. Or their mummy doesn't give a bugger either, and they have copied her slack and lazy ways.
On another note, I've put in the usual number of reports this week - two vandalised playgrounds, a few Energy Australia kiosks with graffiti on them and the odd RTA traffic light cabinet. Energy Australia have been doing a good job of getting to their kiosks quickly and cleaning them.
