The NHL’s first Stadium Series game this season will feature the San Jose Sharks playing host to the Los Angeles at Levi’s Stadium this Saturday. The league has set up a webcam at the San Francisco 49ers’ home stadium to document the rink building process in preparation for the game and, on Wednesday, that camera feed got a surprise visitor in the form of a curious (and terrifying) little birdie.

I’d like to imagine whoever was in charge of monitoring that feed had to change their underpants after this little guy crashed the party in dramatic fashion.
