Birder's Diary is a software program that allows birders and naturalists to maintain detailed records of their sightings.

You can print checklists; automatically maintain life list counts for any region on Earth; recall and report on trends; and much, much more! Birder's Diary is more than a tool just for birders. Checklists exist for mammals, butterflies, trees, and many, many more. More are being added all the time!
