Crows are intelligent birds and learn quickly – even from each other. In Sweden, they are used to collect cigarette butts and bring them to a machine that automatically rewards them with peanuts. (lemmy.ca)

I haven't read the whole thing yet but I couldn't find anything about the effect picking up this toxic shit has on the birds' health. I can't imagine this is healthy for them.

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.
