Wildlife
Kayaking is an outdoor activity. Yes, kids, you'll have to put down your game controllers and go outside. Out there is what us older folks call nature. Nature can actually be quite beautiful and interesting, and you don't have to worry about your screen resolution and refresh rate - both are infinity. So here is a short list of flora and fauna ( plants and animals ) that you might see in freshwater environments:
Birds
Fishes
Turtles, Frogs & Snakes
Mammals
Bugs
Plants
Salt Water
All of the birds listed above can also be found in saltwater environs. The list of saltwater fishes is too long to even start. Insects and amphibians have poor tolerance for saltwater and are not found there, but many other types make up for that. Likewise, seals and dolphins may be found in our bays and inlets.
This is by no means an exhaustive listing, just a few representative types that you are likely to see on almost any trip. I'm going to be lazy here, and filch a lot of material from Wikipedia. I'm keeping this all informal and unscientific; I'm not even going to bother with Latin names. However, if there is something you want to know more about, I will place Wikipedia links.
These are all long-legged, long-necked wading birds typically seen near the water's edge. They will tolerate your approach to a point, and then fly away - one of the advantages of being a bird.
Snowy Egret
The Snowy Egret is very easy to spot, because it makes no attempt at camouflage, and stands out in any environment. They make up for this by being rather wary, although I have seen individuals beg for food from fishermen, a learned behavior that is not common. The Snowy Egret is very common; it would be difficult to go out kayaking and not spot at least one.

This is one of my favorite birds to see when I am out paddling. You're not going to get very close though, a good reason to bring along the binoculars. The Kingfisher is a songbird that thinks it's a hawk. They are actually related to Hummingbirds. You might think that makes them not very aquatic, but I have seen them dive into the water, surface, and take off again, so I guess they put some effort into evolving. ( The Cormorant might want to take notes. ) Kingfishers usually sit in branches near the shoreline, and fly very low and fast over the water.

Golden Shiner
There are many different types of minnows in North America, but the one you are most likely to encounter kayaking is the Golden Shiner, and there is a good reason for this: If you are out after dark and you have a light, they will jump at it and can end up in the boat.
