Furry Boots City
(as in "Fur aboots are ye fae?") Was up in Aberdeen at the weekend visiting Lisa. The Aberdeen University campus and the adjoining River Don and Donmouth Nature Reserve seem like good places to bird. Casual obs included 24 Waxwings near Queen Mother library; two or three drumming Great Spotted Woodpeckers in Seaton Park; Goosander, Red-breasted Merganser and Goldeneye on the river; Turnstone, Redshank, Dunlin and Sanderling near the (locked) hide in Donmouth Nature Reserve. The Chaffinches this far north are just gearing up for song now, while those in London have been singing for several weeks.I looked for the famous Nik-Naks stealing Herring Gull (or was it Doritos?) but no sign. http://news.bbc.co.uk/1/hi/scotland/north_east/6907994.stm Maybe it has a new job cleaning up human rubbish around the city
