Hi all,
Further to the discussion about native species being moved about within
Australia, you only need to go to Perth to see the impact this can have.
Laughing Kookaburra and Rainbow Lorikeet have been introduced there and I
believe are wreaking ecological havoc. Certainly the many thousands of
hollow-nesting lorikeet not native to the area must be impacting on the
numbers of Western Rosella and Red-capped Parrot, while Kookaburras steal
nestlings where they can, and also eat lizards and snakes which would not
have evolved alongside such predators, so this could have serious impacts on
bird nesting and reptile populations. While it doesn't seem like Yellow
Wattlebirds could have a serious impact on the area, who knows - it could be
the next Cane Toad or Crown-of-thorns Starfish?
Regards,
Chris
