I took this in Wyoming last week. I've heard of this happening but have never seen it. This was just a test video used to set the camera up for and longer shot. When I reviewed it and saw what I got was I supprised. Enjoy
Interesting! I've seen this before, but it was because the nectar solution had been in the sun too long and had spoiled - kind of fermenting and producing an alcolhol-like substance. The hummers became drunk and were flying.....well... .drunk! Bees too.
I wonder if this is what is going on here?
I remember hornets doing the same thing after eating fallen pears that had spoiled in the sun. They were stumbling all over the ground and could not fly.
Interesting video. Wjhen I was younger I remember my Mum telling us stories of cows getting drunk from eating all the apples. I guess this is similar to what Sandy mentioned about the Hornets.
