Scientists develop `backpack` computers to track wild animals in hard-to-reach habitats

To truly understand an animal species is to observe its behavior and social networks in the wild. With new technology described today (April 2) in PLOS Biology, researchers are able to track tiny animals that divide their time between flying around in the sky and huddling together in caves and hollow trees-by attaching little backpacks to them with glue.
