Alberta Fish and Wildlife are investigating an incident near Spruce Grove, Alta., after a video posted to social media appears to show a man intentionally hurting a black-headed gull.

The video was posted on Eric Jalbert’s Instagram and Facebook and has since been viewed thousands of times. Jalbert said the video was sent to him on Snapchat from the man. Jalbert said he doesn’t know why the man sent it to him because he doesn’t know who he is.

“This is someone from a province that you might live in, and that someone is doing this to these poor little birds and I got right flustered,” Jalbert said.

“That was an execution, man. You just drilled it into the ground like it was a rag doll, so I do feel bad for the family, but at the same time you have to do what’s right sometimes and if that means getting a little bit of flack from that end of it, oh well, that sucks.” Tweet This

Jalbert said he wanted to share the video to prevent others from doing something like that, and to also hold those who took the video accountable.
