A Bird in the Net (image) University of Utah Caption University of Utah biologist Jen Koop captures a bird in a net in the Galapagos Islands off Ecuador. Koop and other researchers used such nets to capture finches -- the birds studied by Charles Darwin -- and determine they develop antibodies when exposed to two invading parasites, the pox virus and the nest fly.
