Hi Diane,
Interesting recording of the Hermit Thrush...
In listening to this recording, I wonder if your recorder has an
automatic record level control. If so, its a good idea to turn the
automatic record level off when making wild life recordings out of doors
and set the record level manually. The reason being the average ambient
noise outdoors is typically much lower than when recording music which
is typically at a a higher average level than the noise and automatic
level control works quite well. When out doors with a lower average
noise level, the ALC mic level control tries to raise the average record
level to get a good recording of the background noise. The end result is
that when outdoors recording wildlife, an automatic record level control
raises the ambient noise outdoors almost as high as the call of birds
in comparison. If you use manual record level control and set the
ambient noise to indicate a low level on the level indicator, usually
bird calls and animal sounds will record with better dynamic range above
the ambient noise... I think you will find this will reduce the amount
of equipment (mic) hiss noticeably...
