I am not a Twitcher these days, but I do like to know what is about where and still like to see birds new to me or that I have not seen before in my home county. Newcomers to an area, or overseas visitors will, however, find such services invaluable not just for seeing rarities but in appreciating how birds move through an area and what sites are likely to hold good numbers or variety of birds.
These days there are choices from inertial systems such as pagers and smartphone alerts that keep you abreast of birding news as it happens, to birdlines and digests, which you can consult when you are free to do some birding and want to know what’s about.
Many individual states and counties maintain sightings websites and facebook pages… see the appropriate geographical pages for them.
Mailing lists and paging services also appear on their relevant geographical page.
