In an uplifting sign that spring is just around the corner. giant wood storks, great blue herons, anhingas, snowy egrets and other magnificent birds have started to nest in South Florida. In this video shot at Wakodahatchee Wetlands in Delray Beach, Florida, dozens of birds are mating, staking out their nesting sites, and gathering nesting materials, Some of the more ambitious wood storks and great blue herons are already inhabiting t nests. According to Audubon.org, as recently as the 1990s, man-made changes in water flow through South Florida, reduced the number of wood storks -- wading birds that eat fish -- to around 10,000. Wood storks increased their range to rebound to an estimated 150,000 birds. The Audubon site notes that wood storks are the only native stork in North America. Late this spring, Wakodahatchee Wetlands will be filled with the cacophony of dozens and dozens of baby birds squawking loudly for their meals. Wakodahatchee Wetlands is actually run by the Palm Beach County Water Utilities Department. Each day millions of gallons of highly treated wastewater is released into the wetlands to recharge the fresh water water table.
