Viewer Luyen Dao sent in this video of a beaver waving at her son Ryan during a trip to the Oregon Zoo.

Dao was a bit surprised to find the video had started going viral.

Interesting that a video like that has gotten quite a bit of attention, she told KGW. I hope it helps the zoo, it's a great place and we loved visiting Oregon this last summer.
