We have a mature beech tree in our small garden, and for as long as I can remember, the grass would have been littered by now with shells dropped by squirrels and parakeets.
None this year, and I’ve noticed the same in our nearby large park, where there are a lot of mature beech trees - usually filled in early autumn with a lot of noisy parakeets scoffing them.
Similar elsewhere, or just a local thing?
What's one health habit you've started that's actually made a difference?
