Two male Canadian geese caused a bus to halt after fighting over the female.
David Morris, 51, captured the angry birds bust-up, which lasted 15-minutes, on camera whilst walking home in Stalybridge, Greater Manchester.
Several people stopped in amazement to watch the two birds tear each other apart.
David told the Daily Mirror newspaper:
"The birds were really going for it, they weren't holding anything back. It looked pretty vicious to be honest.
"They were so involved with each other that they were completely oblivious to the fact they were fighting in the road.
"Once the bus appeared and couldn't get past, I thought it was really funny and rushed to get my phone out to record it."
