Subject: RE: [Nature Recordists] Migrant Birds
There is a fascinating site that a guy is dedicated to recording and
monitoring migratory birds by recording them with a homemade microphone and
a VCR recorder. Check this web address out.
http://www.oldbird.org/
This is a clip from one of the pages.
The cheapest way to record night flight calls of migrating birds is with a
hi-fi video cassette recorder (VCR). These now sell for less than $75. The
problem is that VCRs typically do not have microphone inputs. They have lin=
e
level inputs that are geared for receiving a much stronger signal.
Therefore, in order to use a VCR to record night flight calls, the signal
from the microphone needs to be amplified. The easiest way to do this is to
find an audio cassette player that has a microphone level input as well as =
a
line level output. The signal from your microphone goes into the audio
cassette player's microphone input and out this machine's line level output
into the line level input of the VCR. Typically, in order to do this, the
audio cassette player needs to be paused in the record mode so the signal
will run through the machine. Inexpensive audio cassette players that have
microphone inputs are getting hard to find in stores as they are being
rapidly replaced by CD and DVD players which don't have microphone inputs.
You might be able to pick up a used or broken cassette deck in a local
electronics repair store. The tape drive doesn't need to work. The deck jus=
t
needs to power up and amplify a signal.

Hello,
Does anyone have any information regarding using sound recordings to
determine the numbers/species of migrant birds flying overhead during the
night - preferably in Britain/UK but references to anything done in North
America would be helpful as well.
Thanks
Pieter Wessels
