Unknown Vocals Investigation

This has been the worst year I've had in 24 years of active field work. Sickness, weather, lockdowns and so on have hindered most plans I had this year. It's been very frustrating.

I call my father every day at 9am without fail. He is more than just my father. He has many roles in the story of my life.  Father, big brother and best friend so after moving out of town to an area that is basically a well paved road through the forest I was and still am very happy for him because he's now in his element, completely surrounded by nature.

During one of our morning calls last year he had mentioned that he and his lovely wife had both heard a variety of vocals that neither could explain. We had talked about many of the other possibilities but my father and I have a lot in common, not the least of which is spending our lives in and out of the woods from a very early age.

In other words when he hears something in the woods that he can't identify I tend to take it a little more seriously than some.
