hm, yes, i toyed with that idea a bit, but i'm pretty sure now that
that's not the case. for a start, these sounds began *before* i heard
any hive activity (the sounds of which are very apparent, especially if
i hold my ear to the wall), in early april, while the hive only became
active several weeks later. 2nd, while the buzzing is relatively
constant at all times of day, these sounds are nocturnal. in the
morning when i wake up the buzzing is still there, but these have
stopped. 3rd, they have occasionally often been accompanied by the
sound of a sort of scurrying movement, too big for bees. lastly,
although maybe it's not clear in the recordings, these really sound to
me like series of short squawking vocalisations from single animals,
several of which can be heard at different points along the wall...
hm, with all the animal id'ing that goes on on this list, i had imagined
that someone would immediately know what i was dealing with. i hadn't
expected to stump nature recordists! well, i suppose most of us don't
spend much time recording ecosystems inside walls... ; )

yes, it only happens with my own self-built contact mics, so i'm sure
it's a problem with them rather than the recorder. i was just wondering
if there might be something i could do to the mics to resolve the problem.
best,
