&gt; Bernard Forsythe's report of last year's uncommonly low (nonexist
Hi John & All,

     I am wondering if an array of these AudioMoths could determine the 
sound source  location by triangulation. If so, then this would perhaps 
enable detection of species at risk activity locations so logging could 
be diverted elsewhere during the breeding season.

An essential component of the Listening Together project is to reach out to community organizations such as yours so I would be glad to come and meet with your group to discuss how bioacoustics might be useful to the group now and in the future. The Listening Together project area includes most of the Valley and the South Shore up to about Bridgewater.

It is strictly prohibited, including pishing, in the North American Breeding Bird Survey, while it is an integral component of other survey methods such as nocturnal owl monitoring routes. My purpose is to offer another alternative, one that, in the long-term, will provide more in-depth and reliable results. We haven't yet developed a survey protocol for owls using AudioMoths, but it would be fun to work on one.

I bought this one to put in forests to determine which birds are nesting in an area.  I'll be interested in hearing more about how you will be putting your units to work.
