Back in June, we presented video of a man calling himself "Jungle Bird" who invaded Webb Simpson's U.S. Open trophy ceremony with a series of squawks. Jungle Bird showed up again today in Dublin, when he invaded the field to perform a ceremonial jig with a football.

When last we saw "Jungle Bird," he was caw-cawing his way through the trophy presentation at the U.S. Open. The deforestation activist has now made his way to Royal Lytham & St. Annes for the 2012 British Open Open Championship.

The roosterlike fellow who invaded last night's U.S. Open trophy ceremony and earned a scolding from champion Webb Simpson has been identified as a kooky deforestation activist named "Jungle Bird."
