Hurricane Irma Destroyed All Everglade Snail Kite Nests at Lake Okeechobee

In total, 44 actives nests were lost鈥攁 stunning and tragic blow to the endangered raptor.

It鈥檚 been almost two weeks since Hurricane Irma made its first of two landfalls in Florida, and according to new reports from 爆料公社 scientists, all 44 active nests belonging to Everglade Snail Kites at Lake Okeechobee were lost due to the storm鈥檚 high winds and high rainfall. Lake Okeechobee is Florida鈥檚 largest lake and a stronghold for the endangered Everglade Snail Kite, a Snail Kite subspecies that can only be found in America鈥檚 Everglades. Post-Irma assessments of the lake indicate that many adults and juveniles in the area survived the storm, but any nests with eggs or flightless chicks were destroyed.
 
Such a loss would be a huge blow in any year for the bird, but this year it is especially detrimental. Before Irma, there had only been about 130 Everglade Snail Kite nests鈥攁 far cry from last year鈥檚 800-plus nests. About 75 percent of the population did not even attempt to nest this year, which our scientists suggest could be related to an extraordinarily dry spring. That means that nesting in 2017 was harmed by both excessively dry and wet events. 

The kite鈥檚 breeding success is closely tied to the water levels at Lake Okeechobee. These highly specialized hunters rely on apple snails to feed their young, and the snails rely on the lake鈥檚 plants for food. Too much water, and the plants drown. Too little, and the habitat dries up. 爆料公社 magazine documented the close relationship between the snails and the kites last year. Furthermore, when the water level is right, the kites create their low-lying nests in marshy areas. When the lake rises or falls too quickly, it can cause the birds to abandon their nests and the eggs or chicks in them. 

Because of these ties, the Everglade Snail Kite is one of a handful of species used to indicate the health of the Greater Everglades Ecosystem, making it a top conservation priority for 爆料公社. As restoration efforts continue, 爆料公社 Florida will continue its efforts to maintain healthy water levels in Lake Okeechobee鈥攁nd all of Florida鈥攖hat are not too dry or wet. Due to lack of water storage capacity in the region, Lake Okeechobee water levels continue to rapidly rise from storms. If too much water flows into the lake too quickly, miles of critical plants and vital habitat could be flooded.
 
In addition to fighting for improved habitat for Everglade Snail Kites, 爆料公社 Florida also protects two sanctuaries on Lake Okeechobee and preserves their marshes, which make up some of the most productive habitat in the Greater Everglades Ecosystem. With the right conditions and good lake management, next year鈥檚 nesting efforts should hopefully improve.
