Resource: Animal Sound Database

[forestfey]

My search wasn't able to dig out something comparable, so...

http://macaulaylibrary.org/

...it's a VERY comprehensive, rather academical database. Since they have migrated, they apparently still haven't figured out some of the... UI problems, though. How sad...
That might a little bit annoying if you're looking for something specific from the start-page, but the advanced search tool provides a whole array of options even a taxonomist couldn't complain about. Just make sure you actually press the "binocular" search button at the bottom.

Be warned, though: Since it's some sort of zoological record or catalogue, most of the sound-files seem to have an according, spoken "index-preface".
If cutting that out is too much work, you should probably look in another database (like I did before I remembered there was something like this). But with those other DBs, you probably can't be so sure that it's really the species you're looking for, compared to MacaulayLibrary?
(if that accuracy is needed at all)
