Peter,
I have a night-vision monocular also. I wouldn't consider it a serious tool
for night birding, but it is a bit of fun. To answer your questions:
- Birds and other animals are distinguishable from the surrounding foliage,
just. Bear in mind that everything is green (just like in the night-vision
effects in the movies). Bird and animal eyes do tend to glow, especially
when you consider the answer to the next question...
- The monocular includes an infra-red light. Switching this on makes a huge
difference. You would have to be careful with a separate and higher-powered
infra-red spotlight, because the night-vision devices are so sensitive that
any bright light (even "bright" infra-red) can cause permanent damage.
- Mine was around $US200. I think it's a Bushnell device. I bought it from a
seller in the US on eBay.
- Mine has 4x magnification.

Some questions about the monocular:
- do things like birds stand out against foliage, or is it just like
looking for them in daylight? Do their eyes glow at all?
- could it be enhanced by the use of an infrared spotlight?
- what sort of cost?
- what magnification?
