I've received the following from the CSIRO at Yarralumla. Can anyone shed
light on this problem or suggest a solution? |
We have an interesting problem at our work, and wondered if your members had any light to shed on this bird behaviour.
We work at the CSIRO precinct in Yarralumla, and there are plenty of birds around, including a large group of choughs.
These have started taking rocks in their beaks and using them to hit the windscreens and windows of parked cars, especially cars parked in one particular spot.
We have already had one windscreen broken and chips on others.
We would be interested to know just what is the aim or cause of this behaviour.
