He who perches high up can see far and wide. These two sea gulls and a lot more make it a habit of perching on the light bulbs. Then they swoop down to snatch the delicious morsel left behond by beach goers.
My kind of Chinese have a saying that our deceased ancestors sit (buried) high up the mountains, they can view far and wide, and will help us avoid disasters and they also see opportunities. So it is very important to choose a good spot for their final resting place.
This is for you Gordon in Adelaide. May be up there, the sea gulls can see across the Tasman sea and see what goodies you have for them.
