FL - Everglades wading birds have a banner nesting season, thanks to heavy rainfall
Late wet season rainfall and a tropical storm in 2021 produced a banner year for Everglades wading birds, according to the latest tally by the South Florida Water Management District.
Across the expansive marshes, from water conservation areas in Palm Beach, Broward and Miami-Dade counties, to Everglades National Park, the number of nests counted in the 2021 season surged past 100,000. That’s comparable to nesting in the 1930s and 1940s, the report said, when drainage work had just begun across the mashes.
The number is the second highest since counting began.
Wading birds thrive when there's a lot of water, followed by a quick drydown that pools prey in easy to fish areas so the birds can feed their chicks. That’s exactly what happened leading into the 2021 nesting season. Rainfall surged in October. Then Tropical Storm Eta dropped more than 20 inches of rain over the Everglades in November.
That led to the second highest nest count on record. The 2018 season, the year after Hurricane Irma drenched South Florida, remains the highest.
The South Florida Water Management District has been tracking wading bird nesting since 1996 as a way to measure Everglades health. Nesting birds reflecting historic water patterns, before the Everglades were dammed and drained.
