Prior to version 3.5, Birder's Diary was sold in two different forms - North American version and World version. The only difference was whether you had access to the World taxonomic list from within Birder's Diary. The functionality was the same. Each license granted use of the full range of features found within Birder's Diary.
Since version 3.5, Birder's Diary has taken on more of an a la carte approach to licensing. What does this mean? It means you purchase the user license you want (Basic or Advanced functionality) and the individual taxonomic lists that you need for your interests (e.g. Birds of NA, Birds of the World, Butterflies, Mammals, Reptiles, Trees of NA, etc.).
To use v3.5 and above of Birder's Diary beyond the 30-day trial period, you must purchase
- Either a Basic or an Advanced User License (not both)
- At least one taxonomic list of your choice (you can purchase and install an unlimited number of taxonomic lists)
Each license is sold and priced separately.
