WFSU Ecology Producer Rob Diaz de Villegas catches the sunrise with Don Morrow, a man who spends many mornings counting the shorebirds along the Gulf of Mexico.

My car struggles to stay straight on the overgrown levies of the Saint Marks Refuge, and my hands stay busy on the wheel. Soon, Don Morrow and I are standing in the dark hearing least bitterns and frogs, and a distant barred owl. We’re in position to count shorebirds.
Don does this roughly twice a month, based on the tides. “I’m looking for a 2.5 foot tide, at least, at the mouth of the St. Marks River,” He explains. High tide today, September 11, 2020, is at about 7:50 am. The high water on the coast will drive shorebirds to the Refuge’s interior ponds, where they’re easier to count. It’s a few weeks into winter migration, and Don is seeing more and more birds with every survey.
But the value of his data isn’t strictly in the season to season numbers, it’s in the year to year. A study published last year found that North America has about three billion fewer birds than in 1970, and that shorebirds have declined by about a third. While the Refuge offers prime coastal habitat, many of its winter migrants breed in the ever warming Arctic. Habitat loss elsewhere could affect numbers here.
