There are about 200 Florida grasshopper sparrows in the wild after decades of development shrunk its dry prairie habitat by 90%.
When a sparrow is bred and released, it has the chance to propel the population closer to a full recovery.
We joined a team of researchers as they released three wild grasshopper sparrows onto a working cattle ranch in Okeechobee.
Each bird weighs less than a paper clip, but the weight they carry is immeasurable.
