[Maine-birds] Re: Mystery songs, 2 of 2

I agree with the junco ID.  I recently watched one junco making this two note call to another who responded with the same call.  Then both would also trill back and forth.

On July 5, we were hiking the Acadia Mountain Trail at Acadia NP.  Near the upper sections we began to hear a distant "tseee-bzzz" double note.  About ten minutes later we had flight notes of 2 (?) Red Crossbills near us, but unseen.  Another 15-20 minutes later, the double-buzz started up again and I chased it down to get the recording here (apologies for wind noise).  This is an outatke from a longer recording.

I never got to see the sound-source and it seemed to move from one tree to another.  At one point I thought there might be two of them counter-singing.  We've considered the possibility that this is not-avian: amphibian or even insect, and that could be.  But the behavior of moving around sure seemed bird-like to me.  Habitat was short firs and pines.

Suggestions most welcome!
