My copy of the new BTO Bird Atlas 2007-11 arrived yesterday. Its big and beautiful with over 700 pages and thousands of maps with information about the populations of our British birds. Evidently about 40,000 volunteers contributed their bird records over the five year period. Sue, Irene, Sally and myself all contributed (a tiny tiny tiny fraction of 1% perhaps!) but the end result is really good. Here we can find all the data needed to chart the decline of many of our species and also wonder at the huge population increases in some of our “new” species eg little egret.
I turned first to grey partridge. Not so long ago this species nested in fields opposite my house. I haven’t seen a grey partridge anywhere since April 2010 near Sandwich. And now I know why.
Now we have got to do something about it.
The book is expensive but definitely worth looking at – at the library perhaps.
