There are several features of the program that are very useful. It has multiple means of searching for a bird whether you know the bird or not. It is possible to search by wing shape, flight pattern, tail shape, range, common or uncommon.
Once a bird is identified there is quite a lot of information available about the bird. (Not as good as some of the best field guides, but good nonetheless.) There are illustrations, pictures, range, facts, identity info, bird song, similar birds and the ability (if in a Wi Fi zone) to connect directly to Flickr or Birdpedia for more information.
I really haven't begun to explore all of the Apps that are available to enhance the birdwatching experience but I know there are some out there. On the basic iPod there is a Notebook feature that is standard. This tool also complements the daily record keeping
iBird may not be for every one but I am growing quite fond of mine. This program is also available for iPhones and iPads.
Birds pictured here today are the Glaucous Gull, the Ring-billed Gull, the Domestic Duck and the Common Redpoll.
