I like birds but would not describe myself as a "birder".
However, i love trying to photograph them as it can be a real challenge with what are usually very uncooperative models.
An interesting point about birds and some reptiles is that their colours often disappear in low light because the colour in their feathers and scales is actually refractive rather than reflective which is why gaudy birds often seem to disappear under foliage and their colours change under different lighting angles.
Personally I admire the dedication of serious wildlife photographers who often lie around in camouflage gear for hours with their huge lenses and costly cameras waiting for that perfect shot.
