Every spring evening, thousands of frogs pipe up with their mating calls in a 3 acre wetland near where I live. At their peak, the din is deafening. I've imagined that it would take 1000 watts of audio power into huge speakers to emulate their volume. This was recorded with an Audio-Technica AT822 mic and a Denon DTR80p DAT recorder. Sorry but a .wav file is too long to upload at the transfer speed available from here.

I wasn't aware that they had found that pollution was the reason. The last I read, the most likely culprit was a fungus disease. Of course, pollution can create the stress to allow a fungus to take root.
As far as pollution on the west coast of North America, I've read that, counter intuitive as it seems, pollution from China reaches across the Pacific. You're probably right that it isn't the same level with prevailing westerly winds from all that ocean though.
My comments were meant as a joke, that there were so many frogs there they must have migrated from everywhere else to reach such numbers.

I don't think the frog volume has been as great in more recent years, but it's still pretty loud. We're close to the West Coast so probably don't get quite the pollution level that you find farther to the east in the US.

Boy, you weren't kidding about those frogs. :-) There must be a million of them. Great capture, can really sense the depth of the sound.
I guess the ecologists concerned about disappearing amphibians haven't discovered your wetland yet. They didn't disappear, they just migrated. ;-)
