Florida has plenty of stories about invasive species we can’t seem to get rid of.
This is the story of one we actually did.
And wildlife officials found them in a pretty clever way.
The African Sacred Ibis is a striking white-and-black wading bird native to Africa. It looks similar enough to our native White Ibis that you might not give one a second glance.
But Sacred Ibises didn’t belong in Florida.
After Hurricane Andrew struck South Florida in 1992, Sacred Ibises escaped captivity. Other birds may have escaped from private collections as well. Over the following years, they began showing up around South Florida — and eventually they started breeding.
That was a problem.
Sacred Ibises have become invasive in other parts of the world, and they aren’t harmless additions to a wetland. They can prey on the eggs and chicks of other birds and compete with native wading birds. By the time Florida realized it had a developing population, officials had a choice: deal with a relatively small number of birds now, or potentially deal with thousands later.
So in 2008, Zoo Miami, USDA Wildlife Services and other partners began an eradication effort.
That’s where the story gets interesting.
The first two Sacred Ibises they caught weren’t simply removed.
They were turned into scouts.
Researchers fitted the two birds with wing tags and 70-gram GPS transmitter backpacks and released them. Then they watched where they went.
The plan worked.
The GPS data showed that the birds were spending their nights on an island at the Calusa Country Club, about seven miles north of Zoo Miami.
And by following those two birds, wildlife officials discovered a larger group of Sacred Ibises in the Kendall area.
The birds had unknowingly led researchers straight to their own colony.
From there, the operation expanded. Reports from wildlife workers, birders and the public helped locate other birds around South Florida.
By the end of the effort, 78 Sacred Ibises had been removed.
Thirty-three were captured alive. Those birds were surgically pinioned so they could no longer fly and were placed in accredited zoological facilities.
Another 45 were lethally removed from five locations.
A few stragglers appeared afterward. Two more were found and removed in 2009, and two were reported and removed in 2011. But the breeding population was gone.
And it stayed gone.
The eradication of the African Sacred Ibis in South Florida is now considered a rare invasive-species success story. Florida caught the problem early enough, before the birds had spread across the state and their numbers had exploded.
Considering our ongoing battles with Burmese pythons, tegus, iguanas, lionfish and countless other introduced species, that’s pretty remarkable.
