From the NY Times an article on our NSF funded collaring technology.  There’s some nice quotes from Terrie on her recent trip to Colorado.
The collars, in development in academia and intended for commercial production in the next few years, use a combination of global positioning technology and accelerometers for measuring an animal’s metabolic inner life in leaping, running or sleeping. From the safari parks of Africa to urbanized zones on the edge of wildlands across the American West — places where widespread interest in the devices has already been voiced, scientists said — the mysteries of the wild might never be the same.

“What you end up with is a diary for the animal, a 24-hour diary that says he spent this much time sleeping, and we know from the GPS where that was,” said Terrie Williams, a professor of biology at the University of California, Santa Cruz, and one of three co-investigators on the project. “Then he woke up and went for a walk over here. He caught something over here. He ate something and we know what it was because the signatures we get for a deer kill vs. a rabbit kill are very different.”
