Bird S$%^e

Took delivery of brand new XC60 last week - got attacked by cherry picking stone sh1tting birds at wifes work today :mad:

I got to work on it with warn soapy but the bonnet is looking pretty nasty. Image below. Any suggestions? If I run a finger over the affected area it feels smooth - its seems to have affected the actual paintwork/laquer.

Here is an image...
