A term used by birdwatchers to describe any bird species that they are observing for the first time. This usually means that the observer saw the bird, but some birders will count species that they only heard and did not see as a lifer. Mostly used in the context of birdwatching, but can also be applied to other outdoor hobbies, such as herping.
Beth: Woah, is that a Yellow-bellied Sapsucker over there high up in that oak tree?
Mike: Sure looks like it! The lack of red on the back of the neck and black border around the throat are distinctive for that species.
Beth: Hooray! That's a lifer for me!
