One of the reasons I hope life is found on other planets is that it would void the anthropic principle, or at least make it irrelevant when it comes to life. If life is found elsewhere, then our existence is not an extremely lucky event needing an entire universe of planets failing to have life to explain it. We would have to look deeper for an explanation than chance which basically says there is no explanation.
Anyway, I found this yesterday about crows killing another crow:

There were also crow funerals but this looked odder to me.
