Animal Sounds

These are the sounds animals "make" in various languages. Can you produce them? Why are some of them similar and others different?
Note: A colon following a vowel indicates a longer duration, and a capital N indicates a nasalized pronunciation. Transcriptions of some sounds were simplified.
