@ahltorp@mastodon.nu Well true of course but I double checked it and apparently even in asocial species they present the same behaviour already in their first year after being born. So they can literally not even observe any other of their pika mates do it. Meaning it is indeed innate. It still is mind boggling. It is not just a seasonal harvest that would have seemed intuitive but they deliberately choose plants with different toxicities according to how long they will ferment. Independent of season.
