I am interested in bird watching as a hobby. An "unfortunate" but intrinsic aspect of it is that since bird species varies between continents, some knowledge is less applicable. When I bought my first book about bird songs in English I did not realize that, it mostly mentioned American species that are not present in Europe. I did not learn much applicable knowledge from it. Another example, in the /r/birding subreddit people are mainly discussing about American birds. Obviously, this is natural and nothing to really complain about. But it often requires to "read between the lines" to understand the location context in a discussion, especially when you are new.
