Sand martins down by the Ribble

Hi there everyone, I spent an enjoyable couple of hours yesterday down on the banks of the River Ribble just outside Preston, I had noticed driving past earlier in the week that Sand Martins were burrowing into the steep sandy banks, so armed with camera set out to get some photos, a few of which are below, and more on my blogsite http://walksnwildlife.blogspot.com/
