Jackie French, the author of The Secret World of Wombats, gives great advice for maintaining a wildlife-friendly garden in her SMH article.

We have an orange tree and a lemon tree, which attracts gangs of cockatoos on their end of the day forage, and possums at night. The cockatoos strew the lawn with half-eaten oranges — they're too good for lemons — discarded after holding the orange in their claw, peeling off the top of the skin with their beaks, and then ripping into the contents like drunks at a cocktail party. After its fill, the cockatoo flies off with a satisfied screech and a squawk... and a new replacement instantly appears in flash of white wings, sparing the tree no relief. At night, the possums race up and down the roof and launch themselves off the roof onto the orange tree.

So there is a lot of noise day and night. But I'll take the din of wildlife over the drone of traffic, any day.

Lovely excerpt and good advice. Tks.

Build a 9 x 5 pond in your backyard and watch the raccoons come. :~(

Install new air conditioning duc work so the possums will have a place to nest. :~(

Buy fancy squirrel-proof birdfeeders and attract hundreds of squirrels to figure out how to dump it out. :~(

Even so, I prefer wildlife sounds over traffic anyday. :~)
