I was out with the family on Sunday at Hardwick Hall in Sedgfield, County Durham. As we strolled around the park I noticed this fella trying to look nonchalant.

The Crow, pest bird or agent of mother nature?

 They are not usually a pest that causes damage to building through their droppings, they more often than not cause physical damage.
I visited a building last year that had thousands of pounds worth of damage caused by Crows pecking the shiny aluminium insulation from the pipes. I have a photograph of the handy work of the pest. I will post it later this week.
Also when I worked for Rentokil Pest Control I visited a office in Newcastle City Centre that had a Crow pecking the insulation out from around the low level windows.
