Magnus, The Swiss recording does not sound like a Swainson's Thrush to me, other than superficially. The spectrographic signature of this call doesn't look right, either. Could this simply be a Chaffinch? Its quite low-pitched, and there seems to be a bit of echo. I rarely hear finches at night in North America--they are for the most part diurnal migrants, like Chaffinch--but it happens. Compare with this recording: http://www.xeno-canto.org/381677
