Ponden South Overflow (c) DCB 2008
In answer to Marks opening photograph at Riddlesden. A bit of a difference here... a concrete retaining wall being used as a nesting bank! Many of the row of circular weep holes half way up the wall are occupied and birds can be regularly seen entering and leaving.

The row of Weep (nesting) Holes can be seen more clearly.

This morning c25 Sand Martins could be seen avidly feeding / gathering aerial food in the lee of the bankside trees and wood. The wind was a SW F6/7 and the birds were having no difficulty whatsoever.
