Bird Nesting Boxes

Bird nesting boxes have been fixed to walls around the Holkham Walled Garden. There are six at the moment although I only found one on Monday having been hopelessly distracted by all the flowers that are blossoming.
To find the one in the photograph, turn left at the gates and stop at the first entrance into the 'Arena of Plants' and look up to the left near the Garrya elliptica.  Jason Hewitt, one of the gardening team, has seen some activity around it so please leave a comment if you notice any lodgers.
