Bald eagle populations are climbing in Georgia.
According to preliminary results, Georgia Department of Natural Resources aerial surveys in January and March documented 166 occupied nesting territories, 124 successful nests and 185 young fledged.
Those totals topped last year’s 163 nesting territories and 121 successful nests, while dropping slightly from 199 eaglets fledged. In 2011, there were 144 territories, 113 nests and 178 eaglets.
The number of bald eagle nests in Georgia has increased steadily, underscoring the rebound of our national bird from near-extinction through much of its range 40 years ago. Nests numbered in the single digits in Georgia when survey leader Jim Ozier started searching for them more than two decades ago.
This comeback was powered in part by Georgians who support the Georgia Wildlife Conservation Fund through their state income tax returns. As this year’s tax deadline nears, those who haven’t filed are encouraged to contribute to the fund through the “Give Wildlife a Chance” state income tax checkoff.
Making contributions large or small through the checkoff – line 26 on Form 500 or line 10 on Form 500EZ – benefits the more than 1,000 Georgia plant and animal species listed as species of conservation concern, including bald eagles.
The large nests of these iconic raptors are showing up in new areas, including Jasper and Carroll counties this year, and more frequently in some coastal counties, such as Chatham, where Ozier documented six new nests for a county total of 25.
“It’s impressive. They’re really filling in the gaps there,” said Ozier, a Nongame Conservation Section program manager with the DNR’s Wildlife Resources Division.
Although the number of young eagles statewide fell this year, Ozier said that change is not significant and fluctuations are expected.
The public is encouraged to let Ozier know about eagle nests they see, reporting them online (www.georgiawildlife.com/conservation/eaglenest) or by phone (478-994-1438). These reports often lead to nests not monitored before. DNR works with landowners to help protect eagle nests on their property.
Bald eagles are no longer listed under the U.S. Endangered Species Act, but they are protected by federal and state law.
Eagle surveys are part the DNR Nongame Section’s mission to conserve nongame wildlife – native animals not legally hunted or fished for – and native plants and natural habitats. The section receives no state appropriations for this work. The Wildlife Conservation Fund checkoff provides significant support, accounting for 12 percent of fund revenues in fiscal year 2012.
All checkoff contributions large and small help. Georgians can deduct contributions from refunds or add them to payments. They can also give when filing electronically or through a tax preparer.

AVM in Focus
In Georgia and other states, scientists are researching the impact of Avian Vacuolar Myelinopathy, a neurological disease deadly to waterbirds, mainly coots and bald eagles. One suspected link is that coots ingest a strain of cyanobacteria or blue-green algae sometimes found on submerged aquatic plants, particularly hydrilla. A toxin in the algae then sickens eagles that eat contaminated coots.
Discovered in Arkansas in 1995, Avian Vacuolar Myelinopathy, often referred to as AVM, has been documented in Georgia at lakes Clarks Hill, Juliette, Varner and West Point, and some small reservoirs near Atlanta. Clarks Hill, also known as J. Strom Thurmond Reservoir, is a hotspot.
A grant from the American Eagle Foundation allowed the Georgia Department of Natural Resources to survey known sites for the disease in November. Ozier spotted numerous eagles then. Yet during DNR flights in January, he saw few eagles at the sites.
Scientists are exploring how to combat the disease. A possible approach is using grass carp, herbicides or both to manage the submerged aquatic vegetation that plays host to the apparently toxic algae.
