These photos were taken a few days apart, but they work well as a mini-set. The first two are of a bold rat picking up bird seed from a rock at the edge of Falmer Pond. The remainder are of a second, more furtive rat, further along the fringe of the pond.
Camera note: all photos taken with the Canon 7D Mark II and EF 100-400mm f/4.5-5.6L IS II USM lens.
