Hi Bob,
Sure.  It's like night mode on my video camera - it actually uses an LED on the 
camera as a tiny spotlight, and the results are monochrome (but it's range is 
extremely short).  What I was thinking was more about finding things and 
perhaps observing their behaviour but certainly for accurate identification a 
photo with white light would be necessary.  At least the amount of bright white 
light used could be minimised.

The other technology which could be used to find animals at night would be star 
scopes.  The images they produce are also monochrome but nothing more than 
existing starlight or moonlight is required.  I've seen cheap ones advertised 
for as little as $350.

Regards,
Rob
