Well, that video will certainly catch you off guard! The NHL and the San Francisco 49ers will be putting on a Stadium Series game at Levi's Stadium this weekend, as the San Jose Sharks play host to the Los Angeles Kings. The stadium is being converted into hockey use as we speak, and the NFL and Sharks have been creating time lapse videos.
Up above, the video features a random bird deciding to make an appearance on the camera. The folks at For The Win described it as a bird that will "haunt your dreams". I don't know if that's necessarily the case, but it will certainly catch you off guard.
Below is a Vine by the San Jose Sharks showing the status of the facility three days before the game. The puck drops at 7 p.m. PT. This bird will probably never go away.
