Derek: The site is good for established species. The ranges are more up to date, including rarities such a Green Violetear and expanding species such as Ringed Kingfisher. Sibley's web site has dots for Green Violetears in places I had never imagined this species had been seen. On the other hand the web site does not show Green Jays in areas of northern South Texas where they have been seen for the past several years. Still, a web site can be updated at much less cost than coming out with a new edition of a field guide. The site did not have information for one-time rarities such as Masked Tityra http://www.greglasley.net/maskedti.html, seen in mid February, 1990, and Social Flycatcher, see in mid January, 2005, http://home.earthlink.net/~pomarine/id39.html . Sibley didn't list the tityra in the 2000 edition of his North American field guide. With those details in mind, don't necessarily expect to find the latest rarest bird on Sibley's web site. It is a useful adjunct to paper field guides. It would not be surprising to see "smart phone" users accessing this site in the field.
Thank you for alerting folks to another useful tool, Sir! Onward!
