20. Forest, at map ref TL 479038, is a large and well established rookery. A few members volunteered to count the nests which proved to be a rather difficult task because of the density. Numbers varied from 120 to 140 - certainly there are over 100 nests here. These nests are mainly in Ash and Oak with one or two in Hornbeam. One bird not heard so much was the Wren. One wonders if Wrens have suffered from the cold winter of 1979. Wood Sorrel, Hornbeam, Primroses, Ash in flower and Oak breaking bud were noticeable as signs of Spring, a late one in 1979. A Comma and a Peacock butterfly were seen by one group in the afternoon. At the end of a very rewarding meeting 22 species had been seen or heard. This number in a warmer Spring could quite easily have reached over 30. M. T.
