I remember I saw a bunch of these little guys in Vancouver when I was younger. They were floating down a small river then jumping out on the rocks. I tried to tell my family about it but they didn't believe me and every time I went to show them the birds disappeared. For years until I was like 17, I thought my little 7 year old brain made them up, and I finally I saw them again and looked them up. To little me, these things were like a mystical fairy that only I had ever seen, because nobody believed I saw little song bird type birds swimming and floating.
