Field Frame Friday: A backpack-ed birdie.

A white-crowned sparrow (Zonotrichia leucophrys) with his spiffy new GPS backpack! These tiny backpacks weigh only 1 gram and take GPS points as the bird goes about its day. We can learn about a bird’s territory at a precise level of detail that we’ve never had before! After 6 days wearing the backpack, we catch the bird again and take it off to learn about its exciting week.
