Nothing to report today due to cool and showery conditions. The afternoon was almost a write-off. Iris was up late this morning due to cool temperatures and was confined largely to the main breeding grounds in Fermyn Woods - the dense sallow jungles. These jungles are surprisingly low and open, with much open ground (rank Deschampsia and Calamagrostis - Grasshopper Warbler country) and sallows in the 2-5m range + scattered young oaks etc. I am convinced that iris is a creature of scrubland, not forest, and not necessarily even of woodland.
