After the opportunities to watch and photograph Red-throated Divers at close hand in 2009 and 2011 and a Great Northern Diver in 2011 in Dover Harbour it was good news when "Chiddy" found a Black-throated Diver in Granville Dock this weekend. As usual getting pictures on the water when the sun is bright provided a challenge and one that I didn't completely rise to. Exposure in these conditions is difficult, the white flanks of the bird often looking quite over exposed. There will be many pictures of this bird around, as a late of hardware has been pointed at it at reasonable close range. below are are few of my pictures from today.
