If there even is such a thing.
There isn't, is there?
Depends on the quality of your encyclopedia. I'm pretty good across a broad swath of eastern North America, in terms of ability to identify birds by diagnostic song and call, as well as a number of mammals, insects, and amphibians. I know people, however, who make me feel like a complete buffoon because they know so much more than I do, e.g., contact call notes of birds in migration overhead in addition to song identification. Where I might be able to identify 150 different sounds, they might know 300.
Nobody knows every sound every animal might make in a given situation, so the best "encyclopedia" in my analogy is something like Wikipedia 10 years ago.
