Woodpeckers in the garden

Hi all,

I live on an estate that backs on to Parkhall Country park. There are one or two other streets between my house and the country park, and also an 'A' road, but it's less than a tenth of a mile away.

I want to attract more birds in my garden - woodpeckers being one of them. I've seen a few of you guys put images up of woodpeckers in your gardens, so of course it's possible. Any tips - will they generally venture away from the forests, across roads?

I'm still very new to the bird world... ;)
