Further to the post below, sorting through some boxed stuff, I have thirteen reports available in total, 1978 and 1982 to 1993. Still available at no cost to anybody who would be interested in them. A mass of interesting info on the birds of our area in those years
I can offer for free (other than postage if needed) to anybody wanting them, Leigh Ornithological Society annual reports for 1978, 1982, 1988, 1989, 1990, 1991, 1992 and 1993. These are A4 size reports, each around 30 to 50 pages of species summaries for the LOS recording area, covering a big chunk of NW Greater Manchester (Wigan-Leigh-Bolton-Bury) plus small areas in St Helens and north Cheshire.
