Notes, Notings, and Common Refrains

I've seen mixed mobs of birds go after a buzzard or sparrowhawk but as soon as they've driven off the top predator then the mob will turn on the next perceived danger such as ravens/crows, or back to territorial competition with their rival species, so their co-operation was always strictly limited.

Humans are capable of being both the most selfish and most altruistic animals ime.
