Where is this? Don't know.

What exactly is going on? Doesn't matter.

All we do know about this video is that it's the cute video of the week. These geese are in a marching band.

Sure, they're not playing instruments or marching in line that well, but it doesn't matter. It's close enough.  

So, just enjoy it for the cuteness that it is bestowing upon you.
