Two FWS biologists tagging a wood stork. Wood storks are widespread in Central and South America, but declined to alarmingly low numbers in the United States. At the turn of the century, there were over 150,000 wood storks living in Florida, while today there are only 7,000 to 10,000 storks in all of the United States. Most of the decline was caused by habitat loss and modification. Scientists hope to better understand the biology of wood storks so that the current population can be protected by wise wildlife management.
