If you're a birder, you'll know what a life list is. It's basically a list of all the bird species one has observed and positively ID'd in one's lifetime. This blog is a record of my "critter" life list (mostly of birds), including photos I've taken over the years, some of the actual lifer if I was lucky enough to get the shot.
