The best thing about this particular tool is its ability to personalize your eBirding experience. By subscribing to a state needs alert, you'll get personalized emails showing recent records of birds you 'need' in a state. Once you report the species, it will no longer appear on your particular alert. This tool is obviously most useful in your home birding state, but also for surrounding states where you might do a lot of birding. You can subscribe to as many alerts as you like, or just view them online.
