17th Aug photos

A few photos from Walthamstow Marshes on the 17th. Just about managed to catch the back end of the Marsh Harrier as it soared low and north; it would've been easy to get much better pictures as the bird came by surprisingly closely, but in those brief situations, a decision has to be made between (hopefully) nice photos or a conclusive ID, and with a large raptor moving through at some speed, the latter was the more sensible option.
