Unwelcome visitor #2

In their place (ie: not in my garden!) I really enjoy watching Grey Herons: they are almost prehistoric in appearance and have subtle plumage details that make them great photographic subjects. Where they are not so welcome is lurking by the side of our small pond waiting to nab one of our ten year-old Koi! Generally speaking, since our garden is fairly small and the pond is right under my office window, Herons tend to stay away. This morning, however, I surprised this individual by turning on the office lights, causing him to flap up onto the roof! (The 'blobs' are raindrops on the window: it's pouring down!)
