It's not a canary or a coal mine in Florida, but the idea from Audubon of Florida is the same. Wading birds hold the same function as the canary, and in this case the coal mine is the Everglades. Tabitha Cale with the society says things are dire.
The 20th annual Wading Bird Report shows some positive and negative stories about Everglades Restoration.
The 20th anniversary of the Wading Bird Report is out and there's some bad news. Everglades restoration is not going well. The report shows that in 2014 there were 34,714 wading bird nests in the Greater Everglades. That's 28 percent fewer than in 2013.
The biggest drops included little blue herons, 83 percent, tricolored herons, 42 percent, and snowy egrets, 47 percent.
Counting wading bird nests is an indicator of where water flows are improving. The report shows the area with great progress is the Kissimmee River Basin. Meanwhile, Everglades National Park still needs improvement.
