This is a random Friday Fun. It's not especially funny, although some will probably think this makes me seem very funny, putting me in the same bracket as collectors of birdsong CDs. Too bad. It just so happened that I was searching for some old files on my computer and came across these - I'd completely forgotten I'd made them. But in the few days before we left Uganda in the summer of 2005, I took my rudimentary digital recorder out into the garden and just let it listen.
