>> James Hi David and all, They probably *could*, but do you realize how difficult it is to have any kind of logging suspended in a forest due to the confirmed presence of nesting migratory birds - even Species at Risk -- even though the Migratory Birds Covention Act exists? A group of us went through all of this at Corbett-Dalhousie Lake last spring with several expert birders having visited and listened and observed birds (including Scott Leslie & Cindy Staicer, just to name a couple of the MANY). Scott even photographed a Magnolia Warbler on its nest. Chimney Swifts were repeatedly seen over the huge partly hollow Yellow Birch by as many as a group of 50 people at one point. Bob Bancroft and I both saw a Broad-winged Hawk there -- and I saw it again a couple of times in the same spot. Little Brown Bats were recorded over the forest with Scott Leslie's bat detection audio equipment. Even with all of that, there was such incredible resistance. *Finally* the logging was suspended due to the presence of the Chimney Swifts, but only over a huge amount of outcry from the many, many naturalists and citizens who saw them there every time we went out to the forest -- but in all likelihood, due to the media coverage from reporters who visited the woods. If photographs of birds on nests, and the listening reports of expert birders cannot force logging out of a very "bird dense" forest -- I don't really know what will. I purchsed an AudioMoth and was about to order 2 or 3 more -- paid for personally by me -- to help our local naturalist get sound recordings to use to prove the presence of nesting migratory birds because they deserve protection. Please note, it is not just "species at risk" that are supposed to be protected, but *all* nesting migratory birds -- contrary to what *some* in the Dept. of Lands and Forestry were telling us last year. We verified this through several letters with the federal government. However, they won't do much to "enforce" these regulations -- they are more into "explaining to industry" and "advising" them how to avoid disturbing birds. It's a real problem because the current modus operandi is just destroying bird habitat and, no doubt, chopping up nesting birds, nests, eggs and young. Here's an article from last June -- there were plenty more as it was constantly in the news in several papers and on radio and TV for several weeks: https://www.cbc.ca/news/canada/nova-scotia/birds-westfor-logging-bridgetown-1.5167928 bev On 2/13/20, David Webster <dwebster@glinx.com> wrote: > Hi John & All, > > I am wondering if an array of these AudioMoths could determine the > sound source location by triangulation.
