I've added a page to this blog, called 'Beddington birds'. Not surprisingly this is a list of the bird species recorded at the world famous sewage farm, with my own personal list highlighted in red. There are four birders who have seen over 200 species there, which is no mean feat for a London sewage farm. You will find some top class rarities among them - Glaucous-winged Gull and Killdeer being the stand-outs. However, there is still no record of Slavonian Grebe or Nightjar. One or two others, that were easily seen when I first trod the paths, are now gone - Grey Partridge and Willow Tit - maybe to never return.
Patch watching is, of course, more than a list. Blogger pages become too difficult to manipulate if they have too much data loaded onto them, otherwise I would bombard you with further Beddington info.
