Amboo: 60 Seconds at a Playground in July
If it’s natural, then it’s a cicada for sure (by the way, this word in my dialect means “spit” 😉 ). Where’d you record it exactly? If you know the precise area, you can track down the song of that particular variety
I did a lot of research several years ago because I needed the sound of a specific Japanese cicada for one of my songs, that’s when I learned (and promptly forgot) a lot of surpriseing things on cicadas, which are actually amazing insects, down to the way they produce their sound (totally different from crickets and grasshoppers).
There’s a shocking number of varieties, each with its own peculiar call (and even the same variety sings slightly differently in different regions of the same country – they have dialects and accents, too O__O )
Anyway, that was years ago, so I don’t have any link handy anymore, but here’s one http://www.insectsingers.com/100th_meridian_cicadas/index.html if you want to give it a try (I will, eventually)
I believe your variety is this one http://www.youtube.com/watch?v=HqewMIh8JEA but there is no information with the video…
Very nice as usual – question: what’s that buzzing noise? Is that some sort of interference or is it some variety of cicada? The dialect is different from the ones I’ve heard so far…
