Upcoming Meetings
March 4th: Former state representative Denny Dobbs from the Newton
County area will discuss the most pressing environmental issues facing
Georgians, the legislative process in Georgia, and what we can do as an
organization and as individuals to address these issues. Mr. Dobbs= interests
lie in environmental issues and he is an environmental engineer in his
private life.
A Note of Thanks to... Paul McClendon for his fascinating talk on the various ways people can use plants and plant products in their daily lives. The gourd collection was especially interesting. Dr. David Krementz for leading the woodcock walk, providing interesting information on woodcock behavior, and finding the best spots to view the courtship ritual. It was an enjoyable evening.

Report on the Loon Walk to Lake Hartwell:
by Elizabeth Little
Fifteen hardy birdwatchers braved cold temperatures
and brisk winds to view the Loons on Lake Hartwell on February 13th. On
the drive to the lake, a male Harrier, Mourning Doves, and Meadow Lark
were sighted. Starting from the Crider home on the lake we obtained immediate
views of not only Common Loons but Pied-billed Grebe, Canadian Geese, and
a magnificent Red-tailed Hawk. On the walk to the boat launch Bluebirds,
Pine Warblers, Goldfinches, White-throated Sparrows, Chickadees, Titmice,
Crows, Robins, Cedar Waxwings, a Yellow-bellied Sapsucker, and Brown-headed
Nuthatch were spotted. Once again on the lake, we immediately saw a Horned
Grebe in the same cove where one was observed the previous year together
with a Ringed-billed Gull, a Red-breasted Merganser, and more Loons. On
the way back to the house Carolina Wrens, Ruby- and Golden-crowned Kinglets,
Towhees, and Cardinals were seen in the brush, and a Hermit Thrush was
heard.
After a delightful and sociable lunch by the fire
in the cabin on the Crider estate, we once again loaded up the vehicles
and headed to the dam area of Lake Hartwell. In a field near the marina,
approximately 400 American Pipets were observed feeding. The caravan continued
to the new campground below the dam. There, with warming temperatures,
Juncos, a Great Blue Heron, Robins, Starlings, Killdeer, Grackles, 12 or
more Black Vultures, Turkey Vultures, Phoebe, Common Yellowthroat and Yellow-rumped
Warblers, and Swamp, Savannah, Song, and White-throated Sparrows were spotted
in the surrounding wetlands, field, and woods. A Winter Wren gave everyone
a good view as she fed in the grass. The woodpeckers were numerous and
varied with sightings of Downey, Hairy, Yellow-shafted Flicker, Yellow-bellied
Sapsucker, Pileated, and 3 to 5 Red-headed. The bird watching continued
until dusk to end a very successful day. Thanks especially to Minnie and
Wally Crider for again letting us use their home to gather and lunch.
Highlights of the Annual Woodcock Walk
by Owen Kinney
On the afternoon of February 6th, Oconee Rivers Audubon
traveled to Greene County in search of our most distinguished shorebird,
the American woodcock. Dr. David Krementz, a local woodcock expert and
ornithologist at Patuxent Wildlife Research Center, kindly led the group.
We met at Watson Springs, site of a ghost town abandoned decades ago after
it's claim to fame, a medicinal spring, dried unexpectedly. The spring
has since returned, along with many of this region's typical bottomland
shrubs and hardwood trees. On a short walk through the old town and
the surrounding woodlands, David shared his knowledge of cutting-edge forestry
techniques, ecological impacts of non-native plants, and, of course, the
elusive diurnal activities of the American Woodcock.
As dusk approached the group made haste toward a clear-cut
area where David had seen woodcocks on previous evenings. Armed with flashlights
and binoculars, we crossed the treacherous Watson Gulch (those who weren't
there missed some outstanding teamwork) and, eventually, reached a grassy
hilltop. Eager to experience the male woodcock's crepuscular courtship
ritual, we listened intently to David’s descriptions of the bird's spiraling
display flight and subdued vocalizations. As the sun set, we settled down
around sparsely vegetated patches of ground, each of us hoping to select
a front row seat to the evenings festivities. Just before twilight raspy
peeeent! calls began sounding from all directions. Soon we began to see
birds springing from the tall grass and flying upward in wide circles.
A warbled series of chips and whistles, produced in part by specially modified
primary feathers, became audible as the birds descended. Some lucky
birders were even able to hear the quiet clucking call given by males as
they strutted through their lek routine. In the end, although none
of us took advantage of the free hydrotherapy, I think seeing such intense
wooing may have rekindled some romantic feelings...just in time for Valentines
Day.
Breeding Bird Atlas Reminder
The Georgia Breeding Bird Atlas, initiated in 1994 by
the Georgia Department of Natural Resources (GA-DNR), will be continuing
on this year. Volunteers are needed to survey designated areas in
the state and verify breeding of all avian species. This data will
provide the first complete picture of bird distribution and establish a
baseline from which future changes can be measured. This information will
be used by GA-DNR, other governmental agencies, land use planners, and
researchers to aid in conservation of birds in this state. Some of
the interesting observations that have been made as a result of the survey
include reports of Cliff Swallow expansion southward in the state, verified
nesting of American Kestrels in downtown areas of Atlanta and Blackshear,
the first confirmed breeding of Tree Swallows in Georgia, and increased
sightings of Swallow-tailed Kites (no confirmed breeding as of yet).
The Athens area falls within two regions: areas north
of Athens in Region 2 (Jackson, Madison, Franklin, Banks, Barrow counties)
and areas south of Athens (most of Clarke, Oconee, Oglethorpe, Walton counties)
in Region 4. The Region 2 coordinator is Jim Flynn, 6360 Lillie Lane,
Cumming, GA 30040, (770) 886-6029, email: jflynn@america.net; the region
4 coordinator is Joel Volpi, 2680 Sandstone Drive, Lawrenceville, GA 30243,

American Redstart Summer Breeding Success Depends
on Winter Feeding Habitat:
Researchers in a recent paper in the journal Science (282:1884-1886)
were able to correlate the type of winter habitat that the American redstart
occupied in the Caribbean with the physical fitness of the birds at the
end of the winter and with the time of arrival at breeding grounds in New
England. Birds were observed to occupy two types of habitat in Jamaica:
a black mangrove forest in which males predominated (65%) and a drier,
second-growth scrub habitat in which females predominated (70%). Birds
wintering in the mangrove forest were found to have maintained or gained
body mass while those in the scrub lost up to 11% of body mass. Dominance
behavior by older males forces younger males and females into the drier
and poorer-quality habitat. Body mass was inversely correlated with departure
time for the northern breeding grounds and implies that redstarts in better
physical condition can leave sooner and occupy the best breeding grounds.
Previous research has shown that arrival time at the breeding grounds is
a major determinant of fitness in migratory birds. The level of an isotopic
marker in the tissue of birds caught as they arrived in the north was used
to determine in which habitat each bird had wintered. The researchers found
that the early arrivals in the breeding grounds, which were predominantly
males, had wintered in the richer mangrove forest. However, mangrove
forests are in decline worldwide and the results of the research suggest
that the optimal wintering grounds for redstarts may be saturated and therefore
limiting. This conclusion has important implications for the long-term
stability of migratory bird populations, many of which are declining and
of concern to conservationists.
Did You Know?? (from Energy Technology Choices) Before DDT, American farmers lost about a third of their crops each year to insects, weeds, and disease. Today, with an annual pesticide bill exceeding 1 billion dollars, farmers still lose the same one-third share.
Legislative Update
by Marta Daniell
SB 57, the Governor’s Georgia Regional Transportation
Authority Bill, passed the Senate on a 45-10 vote on Friday, February 5th.
The House Transportation Committee plans to examine the bill on February
11th. With a vote coming as early as February 17th.
This bill will have a tremendous impact for Atlanta
and the rest of Georgia by improving Atlanta’s air and traffic, preserving
rural farm and forest land and improving the mobility of Atlantans and
those who visit there.
Many of you are aware of the issue involving large hog
operations. I late January the state Board of Natural Resources voted unanimously
in favor of a moratorium on state permits on new hog farms with more than
2,500 swine. The State Department of Agriculture is concerned that farmers
were not given an opportunity to express their views on the subject.
The Sierra Club and other environmental groups are concerned
that Georgia’s rules are too lenient and will result in the pollution of
some of our land and water resources. In 1995, a 23 million gallon hog
sewage spill into the New river in North Carolina led to severe pollution
of 17 miles of the river.
Hog farming regulations must be approved by the Department
of Natural Resources Board before they can become effective. A meeting
to discuss the regulations will be held on February 23rd in Atlanta. Please
contact your DNR Board member and let him/her know that you are concerned
about lax regulations that favor the hog farmer
over the environment. Your Board member is from your Congressional
District. I’ve listed the members in surrounding Districts.
