Q&A – Which bird LR keyword list is best for me?
If you want to use UK bird names when keyboarding you should choose Birds of the World version 2.11C, 2.11E, or 2.11F. The main differences between these keyword lists are that in version 2.11E you will in addition get US names added as keywords to your bird images, and in version 2.11F also Norwegian names.
If you prefer to use US names when keywording, the answer is very simple: choose version 2.11D.
