Despite living in a street almost completely full of units/flats/apartments, there's a thriving population of flying things around, helped no doubt by a seldom-broken canopy of trees lining the footpaths, and no overhead wiring. Also, one positive about living in a street full of flats is there almost complete lack of cats/dogs wandering the neighbourhood - probably another reason for the flourishing birdlife.
My parents' place in the outer suburbs is close to the bush and has a great selection of birds. They have a bird feeder and a birdbath, though it would be more accurate to call it a bird/ [link|http://www.alkirna.com.au/images/brush-tailed%20possum.jpg|possum]/[link|http://www.geocities.com/liveattentively/antechinus.jpg|antechinus]/cat feeder.
They receive regular visits from [link|http://www.birds-nest.com/birds/cockatoo.gif|Sulphur-crested Cockatoos], [link|http://teachingtreasures.com.au/Photo%20Gallery/magpie.htm|Magpies], [link|http://www.geocities.com/liveattentively/currawong.jpg|Currawongs], [link|http://homepages.ihug.com.au/~don/images/Birds/Butcher%20Bird1,%20large.jpg|Butcher Birds], [link|http://www.micktravels.com/australia/great_barrier_reef/120-kookaburra.jpg|Kookaburras], and [link|http://www.abc.net.au/science/news/img/lorikeet.jpg|Rainbow Lorikeets]. The Lorikeets are the coolest as they're more than happy to sit and eat out of your hand.
Uninteresting fact: I've only ever seen 1 Cockatoo that didn't hold its food in its left foot whilst eating.
