Well that was fun! In the event, my Zoom broadcast on the wildlife of the Yare Valley attracted an audience of seventy, including joiners from all over the UK and as far away as Spain! With a Q&A session at the end, the presentation lasted well over ninety minutes: I had quite a sore throat by the time we wrapped up at 9.10pm.
A number of people were keen to get hold of a copy of my book 'Birds of the Yare Valley': it is, of course, available on Amazon and at various reserves around the County, but if you e-mail me at firstname.lastname@example.org, you can buy one (signed even!) for just a tenner - that's £2 less than online!
