JC's Birdwatching and Natural History Links is a Home Page made up entirely of links to other interesting sites. Unlike many such hubs of WWW materials, this particular site's concentration is not limited to information concerning North America. It also includes comprehensive data from Switzerland, Scotland, England, Wales and other countries. All of the birdwatching FAQs are available here too, as well as a link to the Usenet newsgroup rec.birds.
