I‘ve found an old archive film of RSPB reserve The Lodge from way back in 1961 on YouTube, which was the year that the RSPB bought that reserve as there headquarters. I can’t provide a link as I’ve got YouTube as an app on my Apple iPad. But if you do a search on YouTube, typing in, A Place For Birds, you should find that old film that I suppose was made by the RSPB Film Unit way back in 1961. One thing I did notice in that old film you could hear lots and lots of Turtle Doves.
Here's the vid Ian, thanks for letting us know
Will have a look when in bed instead of reading!
