What kind of equipment do you use in your work?

A crested argus looks a bit like a peacock.

We use radio collars to track animals, and, in Vietnam, we use camera traps, which send out beams of light. We put them in the forest, in the places where the animals come out at night. Animals trip the beam, and the camera takes a picture.

In Vietnam there is a beautiful bird called the crested argus. They look like peacocks, with beautiful, five-feet-long tails. We put the cameras in a depression in the forest where we thought the males would do a courtship dance.

When we came back, we discovered that all the film was used up. Imagine how excited we were when the film was developed—we had phenomenal pictures that have helped us understand the behavior patterns of this species of bird.
