In case anyone else was skimming through to find over what time period this occurred.
- jabiko 3y agoThanks. It's always a bit annoying when someone throws around percentages of changes without giving the time frame.
- Symbiote 3y agoThe authors of the paper give the percentage right next to the time (as quoted), it's the submitter who has invented a new title.
- DrBazza 3y agoWhen I was a kid growing up in the London suburbs in the 70s and 80s I could remember flocks of all types of birds especially starlings and blackbirds being common place, and then, reading this article, it reminded me that I stopped seeing flocks. Even now, living outside London, I rarely see flocks of birds, and if I do, nowhere near as large as I remember, and I don't think its observer bias either.
