In June of 2019, my wife Nancy and I attended the Rangeley Lakes Birding Festival in Maine. One of the highlights was a guided drive up a logging road to search for breeding Blackpoll Warblers. Nancy was the first, and only, member of our group to hear them singing on territory. Our guide, a local wildlife biologist specializing in this bird, was not convinced they were present until Nancy caught them in her scope with their mouths open, singing away. It was a sobering moment as our guide came to grips with the reality of his hearing loss. It was cold comfort knowing I was not the only one of a "certain age" who had lost my high frequency hearing range.
