Monomonday: Rock

Two rocks, that is, and a bird. My plan was to blip the massive foundation pillars of St.John's Bridge. Looked like they were made of cement though, and that did not seem like a legitimate rock. 
So I turned my focus to the various size rocks on the shore. The river is very low, rocks that are usually underwater are now high and dry.Then the birds came and started foto bombing... In the end I had a hard time choosing a favorite, so there are several extras.
