Detalhes da observação
Confirmed by Matt Young at Cornell from spectrogram in audio (see RECR above). Note- the birds observed are Type 10/7 RECRs. Matt clarified that their spectrogram has upticks with tails, but Matt is still identifying them as Type 10s for now. He said the 10/7s are widely known from southern Maritimes, south through Maine to central NY and Mass, and across central Quebec and Ontario through the Great Lakes to Minnesota. They "irrupt" southward every few years, mostly along coastal areas, to PA, RI, NJ and Delaware, Maryland, Virginia. Matt Young et. al. are currently studying Type 10/7s further.
