When I first started birding all I kept was a life list, but the enthusiasm of other listers rubbed off on me and now I find myself keeping an ABA life list, state lists, and year lists. I haven't gone so far as to keep county lists and am still not interested in them, but since eBird calculates them for me I may someday start to keep track. I've kept backyard lists in the past, usually when I'm off somewhere for a field job or field work. I don't really keep a list for my current apartment.
I keep a Bigby list- all the birds I find by walking/running/biking from home for the year, and I suppose starting next year I'll start a cumulative Bigby life list. I know at least a few others around here keep this list as well.
I've recently started keeping a list of all the birds I see/hear while running in a marathon- starting with the Mississippi Coast Marathon last weekend, with 32 species including Brown-headed Nuthatch. I once kept a list of all the bird species I heard a Northern Mockingbird imitate: that was when I worked down in Florida, I heard the mockingbird in our front yard imitate interesting birds like King Rail and Burrowing Owl, so I started keeping track.
So... what lists besides life and year lists do you all keep? Anybody have any unique or unusual lists?
I have state lists for Minnesota and Nebraska.
My life list says the state the lifers were found in, so I do not keep a list for my home state. I could calculate it any time.
Must admit to being an inveterate list keeper myself. Garden ( Yard ), local patch, Wirral, UK, year and life lists, plus national one's as well. My shortest list is my Afghani one with three Eurasian Griffons, seen from a plane over Afghanistan! Does this make me a really sad bastard ( I don't keep a TV list though!)
