If you get those sounds recorded let me know. I'm very fascinated by all the different noises they make.I'd like to get a collection of quail noises on video some day, though it might stress out some quail. I think everyone has heard the "Co-turn-NIX" crowing, and it's easy to find it on youtube, but I think there's a lot of other sounds that are less well-known. Here's what I've heard so far:
Crowing: I've seen it said that female quail can crow, but I don't think I've ever seen any quail keepers on this forum report this. Sounds about as close to Coturnix as chicken rooster crowing sounds to Cockadoodledoo, which is to say, quail crowing sounds more like Err-err-ERRRR. Males will stand tall and their whole heads will shake with their crowing. As far as I can tell, males will crow to call the rest of the covey.
Growling: Only roos will make this noise, and it seems to be a sound of displeasure. It sounds like a rusty 'rrrRRR'.
Egg song: Hens will typically make this sound after laying, and it sounds like a cartoon bomb dropping with laser gun shots. A descending whistle with a 'pew pew pew' sound after it.
Locating call: Hens will make a cricketing 'ree ree ree' sound to call to the covey - I've seen hens make this sound in response to roos crowing or when they're away from the covey. I've also seen them make this sound when I approach the cage - no idea if they're calling *to* me or warning the rest of the covey. Typically it's one of the more...dominant? hens who calls in that case.
Peeping: Typically a sound made by chicks and rarely by adult birds. It's pretty much what you expect - a high-pitched "peep-peep-peep" sound. We had three adult birds who would do a louder, screamier version of this and it seemed to enrage the other birds - especially the roos, who would chase them and scalp them.
Some calls I've personally never seen described elsewhere:
Chatting: I've only really heard this from our male, Sugar, and typically while he's alone with us humans or with one hen. It's quiet and chirpy - I'll make this noise back at him and it sounds like "pi-chi' and 'chi-chiriri'. It doesn't seem to be a frightened or angry noise - not sure what this noise is for.
Threat noises: Seems to be different between males and females. My husband had accidentally put Jason in with Sugar and they would make this noise shortly before getting into a fight. I don't have a strong memory of this noise, but iirc was a constant, almost ululating noise like "bi-bi-bi-bi-bi." Pudding, our hen, made a similar noise when she was attacking Sugar, but it was...chirpier?
