Bald eagle populations are soaring in Georgia.

     According to preliminary results, Department of Natural Resources aerial surveys in January and March documented 158 occupied nesting territories, 116 successful nests and 190 young fledged.

     The totals are up from last year’s 142 nesting territories, 111 successful nests and 175 eaglets.

     The number of bald eagle nests in Georgia is steadily climbing, 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 $2 or more to the Wildlife Conservation Fund - line 26 on Form 500 or line 10 on Form 500EZ.

     Giving 2 wildlife benefits more than 1,000 Georgia plant and animal species listed as species of conservation concern, including bald eagles, which are continuing to nest in new areas across the state.

“They’re now in places I never would have thought they’d show up,” said Ozier, a Nongame Conservation Section program manager with the DNR’s Wildlife Resources Division. Examples this year include the campus of Berry College near Rome and a

rural Piedmont Georgia farm that is not near a major reservoir or river,
the usual source of fish, birds and turtles that eagles prey on. Eagle
populations in Georgia are concentrated along the coast and around
reservoirs and rivers.

One new nest that proved no surprise is on Lake Lanier. Although an
eagle nest had not been documented before at the 38,000-acre North
Georgia lake, bald eagles have often been seen there.

The number of young eagles fell this year just shy of 2010, when the
survey counted 194 eaglets. Ozier said warmer than usual weather might
have resulted in eagles nesting and raising their young earlier, with
some eaglets fledging before the survey was taken. Yet, fluctuations are
also expected.

The public can let Ozier know about any eagle nests they see, reporting
them online (www.georgiawildlife.com/node/1322) 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.

Eagle surveys are just part the DNR Nongame Section’s mission to
conserve nongame wildlife - native animals not legally hunted or fished
for - and native plants and habitats. The section receives 
no state appropriations for this work. The Wildlife Conservation Fund
checkoff, also called Give Wildlife a Chance, provides significant
support, accounting for 9 percent of fund revenues in fiscal year 2011.

Georgians can deduct checkoff contributions from refunds or add them to
payments. They can also give when filing electronically or through a tax
preparer. Go to www.georgiawildlife.com/TaxCheckoff for details. Please
consult a tax professional about deducting contributions.

AVM IN FOCUS
In Georgia and other states, scientists are researching the impact of
Avian Vacuolar Myelinopathy, or AVM, 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, 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. Eagle nesting territories on the lake have
dwindled from eight to one, Jim Ozier said.

Scientists are exploring what can be done to combat AVM. A possible
approach is using grass carp or herbicides, or both, to manage against
the submerged aquatic vegetation that hosts the apparently toxic algae.
