Occasionally a jackdaw gets robbed as they are rewarded for depositing litter. Today a jackdaw got jumped by another just as they collected their reward. I've seen theft, but this is the first scuffle I've noticed. I guess this is the bird version of getting mugged at the ATM.

The fight starts at 0:46 and lasts for 4 seconds. Nobody was hurt :) You see both birds fly away a moment later.

They knocked in a bit of debris that triggered a dispense during the fight, but were too busy to notice so another bird got it.
