Mumsnet mavens! What do you know about ravens?

[kicker]

Or rather crows who are destroying DS's new goal net (again) Is there anything I can do to get them to stop?

Are they finding a food source like little bugs on the goal net?

You can buy kite-type larger birds eg raptor shaped as crow scarers. They are on a long flexible pole (like the flags at Glastonbury).

Good luck as they are very intelligent birds.

Would dvds hanging up help scare them off? They like to perch which might be the problem
