I once had the opportunity to watch two crows attacking a swarm of sparrows.
I've never seen birds hunting birds before so it made me watch the whole scene for 3-5min and I was baffled how the crows systematically 1) induced chaos trying to isolate a sparrow from the swarm then 2) killed it and 3) while one crow was busy eating it the other crow kept the infuriated swarm at distance. After a while 4) the crows changed jobs.
