There is an ‘arms race’ going on in suburbia that has nothing to do with automatic weapons, at least not yet.
Instead it appears birds are evolving to outsmart our attempts to keep them out of our bins in what scientists are describing as an ‘interspecies innovation arms race’.
A study has found cockatoos in Sydney learnt how to open rubbish bins but have also transferred that knowledge among their populations.
First they learnt how to open the bins, and then when residents tried to foil their raids with bricks on top of the bin, they started pushing them off. It was behaviour first noticed in only three suburbs in 2018, but had spread to 44 suburbs by 2019. Freaky.
Apparently they still can’t overcome a stick in the hinge, but give them time.
Do you have problems keeping birds out of your bins? What do you do?
