Several years ago I was visiting one of my favourite spring birding locations. I stopped at the base of a small waterfall where the water pooled and formed a stream that connected to some other body of water (Hudson River I beleive). Imagine my surprize when I see a bunch of really pretty fish all excited and I suppose mating. I took video of the event and posted it on you tube and got still to post on iNaturalist. I am providing the link and I hope you guys enjoy it. You just never know what you can find.
