palm squirrels interesting stuff. the indian palm squirrel was imported into australia so it could be introduced free-ranging to the grounds of both taronga zoo in sydney and the perth zoo. today they can still be found wild in perth all within a few kilometer radius of the original zoo release site. they are subject to an eradication program, i believe, only outside of this area (anyone know anything more about this?). the sydney colony died out as did the american grey squirrels that used to roam the parklands of melbourne. palm squirrels create a very loud whistling or chirping sound that i had always assumed was made by birds. it wasn't until i saw it for myself that i eventually lost a bet with an indian man and had to concede that the very irritating noise i could hear was in fact from one of the squirrels that scurried, gecko like, up the building walls of virtually every city i have ever visited in sri lanka and india. they are nonetheless quite an attractive little creature - though probably not what you first expect when you think of a squirrel. unlike european species they tend to stay on four legs (they dont sit up - acorn in hand) and are quite small - therefore baring more resemblence to striped rats with bushy tails!
