I was at a hotel a while back and behind my room was a field full of cows. I was looking out the window at them and noticed that one of them was licking a crow that was sat on the ground. The crow didn't seem to mind being licked (and it was a whole tongue lick, not just the tip, it was pretty much lifting the entire crow off the ground with each pass), and then after a while it flew off. I wasn't high, this was at 9 in the morning.

What's the weirdest interaction between two different species of animal you've ever seen from a hotel window? Or from, anywhere I suppose, in the interest of not making this thread to niche...
