Gordon Kirk, while organiser of the BTO Bird Atlas fieldwork in Gloucestershire, issued a regular newsletter, which he called the “Gloucestershire Tetradder”. Now that the national Atlas, like the “Birds of Gloucestershire”, of which Gordon was one of the co-authors, is completed and published, he intends to continue producing the newsletter with the same title – even if we are no longer surveying atlas tetrads. Here is the latest version. Please send any comments direct to Gordon.
