I got good results placing my Zoom H2 in the midst of a large Common Raven
roost just before the birds started to return. I let it record as long as
the card would last and picked it up the next day after they had left. Some
very interesting recordings including the first arrivals, building to a ver=
noisy peak with 2000+ birds, then slowly diminishing as the birds went to
sleep...quiet enough to hear the occasional 'splat' of bird droppings
falling nearby. Luckily, no direct hits on the recorder! The cards (or
batteries, in winter) don't last long enough to capture the wake up and
departure, but maybe with the Olympus model with the built-in timer.
I doubt that most birds would be disturbed by a mic / recorder / cables
(though they may not perch right beside it), but the probably would be
suspicious of any remote-controlled movement.
