Several weeks ago, I posted a blog regarding the presence of avian flu in Georgia and its possible impact on the birds that visit our feeders. At that time, I promised to provide you with any new information that becomes available. A May 17 news release issued by the Georgia Wildlife Resources Division updated the status of the disease in Georgia.
According to the Division’s wildlife biologists, data regarding the incidence of avian flu suggests that the vast majority of Georgia’s songbirds are not at risk of catching the dreaded disease. The songbirds that are at the highest risk are those living near domestic poultry flocks that have become infected with the disease. However, the Georgia Wildlife Resources Division emphasizes that the only birds share an elevated risk of catching the disease are scavengers such as vultures and crow.
Fortunately, to date, avian flu has not been detected in any domestic poultry flocks in Georgia.
The short list of birds that have been infected by the disease in the Peach State is restricted to waterfowl and eagles.
For those of us that feed birds in our yards, the bottom line is we can continue to feed birds at our feeders without the fear that our efforts are helping spread the disease.
However, Wildlife Biologist Todd Schneider emphasizes that feeders and feeding areas should be kept as clean as possible. This will ensure our feathered friends will not suffer from house finch disease, or one of a host of other fatal or debilitating diseases spread by organisms that thrive on wet, and moldy seeds.
Captain John Smith, a leader of the Jamestown Colony, is widely credited with naming the opossum.
Supposedly, Captain Smith came across an opossum while in the company of a member of the Algonquin Tribe. When Smith asked the man what this strange looking animal was called, his companion told him it was an “aposum.” The Native American name referred to the long-tailed animal’s white face. However, as luck would have it, as the man uttered the word “aposum” he grunted. This led Captain Smith to believe he said possum. Is this story true? We may never know for sure. What I do know is the opossum is indeed an odd animal.
At this time of the year, it is common for adult birds to appear at our feeders accompanied by their fledglings. When this happens, we are able to observe the young begging for their parents to feed them.
The fledglings’ parents have been feeding their young in the nest for quite some time. Interestingly, once their brood leaves the nest the adults will continue to feed young birds for anywhere from one to three weeks. During this time the young birds will make their first attempts to feed themselves. However, most fledglings would undoubtedly starve if their parents did not continue to feed them.
When a family of birds arrives at your feeding station the youngsters will sometimes perch atop or nearby a feeder waiting for a parent to feed it. However, it seems that more often than not a fledgling will perch alongside a parent that is dining on seeds or other foods. In an attempt to coax a parent to feed it, a fledgling will typically anxiously chirp at an adult while rapidly fluttering its wings. This usually does the trick and the parents succumb to their youngsters begging.
This morning I watched a family of house finches arrive at one of my sunflower feeders. Immediately the fluffy, drab youngsters began begging for food. Their irritating behavior worked and quickly the parents were placing food in the large, gaping mouths of their young.
As I watched this fascinating behavior, I said to myself, “Little guys, you had better enjoy the free lunch while you can as it won’t be long before you will be fending for yourselves.”
For reasons that are not fully understood, some orchard orioles will nest close to the nests of eastern kingbirds. This might come as a surprise since eastern kingbirds have the reputation of aggressively defending their nests. Well, many experts believe that this is the reason why orchard orioles will choose nest sites sometimes within mere yards from the nests of eastern kingbirds.
It seems obvious that kingbirds do not feel threatened by North America’s smallest oriole. However, when kingbirds fly out to confront a crow, common grackle or other potential avian nest predator flying close to their nests, they unwittingly also defend the nearby nests of orchard orioles.
Some studies suggest that this behavior may translate into real benefits for the orchard orioles. Studies have shown that, when the nesting success of orchard orioles that nest close to eastern kingbirds was compared with the success of those that do not, they discovered the nesting success of orioles that nest some distance away from eastern kingbird nests was lower. In fact, there also seems to be a correlation between kingbird populations and orchard oriole populations. When eastern kingbird numbers are high orchard orioles are more abundant too.
Since there is a paucity of natural bird nesting cavities throughout Georgia, Carolina chickadees often have to compete with eastern bluebirds for the same nesting boxes. When this occurs Carolina chickadees usually end up looking for another place to nest. There are, however, ways in which you can provide a nesting site of Carolina chickadees.
One approach is to equip a nesting box with an 1 1/8-inch
entrance hole instead of the 1½-inch hole featured on standard bluebird boxes—bluebirds simply cannot squeeze through a 1 1/8 –hole.
However, Carolina chickadees can enter nesting boxes 1 1/8 inches or larger in diameter. Consequently, even if a pair of Carolina chickadees begins nesting in a standard bluebird box, the pair is not guaranteed their nesting attempt will be successful.
One reason for this is bluebirds will actually run off chickadees even after they have begun nesting. It has also been documented that bluebirds will deposit their own nesting material over Carolina chickadee hatchlings.
With that in mind, consider dedicating one or more nesting boxes for Carolina chickadees. If Carolina chickadee nesting boxes are not readily available in your area, and you don’t have the means to build your own box, all you have to do is install a metal hole guard featuring a 1 1/8-inch hole over the 1½ hole cut in the box. Problem solved.
Recent reports that a new virulent strain of avian influenza (HPAI) has been found in wild birds in Georgia and more than 29 other states have raised concerns that feeding backyard birds might play a role in the spread of this deadly disease in the Peach State.
To date, the only species affected by the disease in Georgia have been lesser scaup, gadwall, and bald eagle. However, avian flu has been detected in at least 100 species of wild birds and other animals.
Avian influenza also infects chickens, wild and domestic waterfowl (ducks, geese and swans), quail, pheasants, and other domestic birds,
The disease is spread in the droppings and nasal secretions of infected birds. It has also been reported healthy birds can also catch the disease when they walk across surfaces contaminated by infected birds.
While it is possible for wild birds to contract the disease form domestic poultry, the United States Department of Agriculture (USDA) has found that, in every case they have investigated this year, domestic flocks were infected by wild birds.
Fortunately, as of March 30, no commercial or backyard flocks of poultry have been infected in Georgia. However, such is not the case in 23 other states. Most of these outbreaks have occurred in the Midwest and East. This has resulted in the slaughter of 27 million chickens.
If you enjoy feeding birds in your yard, you are probably wondering if you should cease feeding bird in your backyard until the disease subsided. So far, the Georgia Wildlife Conservation Section has not recommended that people stop birds in their yards.
However, the Georgia Wildlife Conservation Section urges the public to report dead or sick eagles to their office in Forsyth (478-994-1438). (Three bald eagles were found killed by the disease along the Georgia Coast.)
In comparison, the USDA suggests that homeowners can continue feeding birds unless they keep domestic birds. On the other hand, extension specialists at Cornell University recommend that the public cease feeding “until the threat of the disease has passed.”
I will let you know if the outbreak becomes more serious in Georgia and if Georgia officials issue any recommendations concerning feeding wild birds. Those bloggers that live in other states should check with their state wildlife agencies to see if they recommend that feeding birds be discontinued in their states.
Recently my wife and I attended THE FLOWER FANTASY AT PINEOLA FARMS located near Fort Valley. The flower show was sponsored by the Magnolia Garden Club. The event was great and the most unusual and fascinating flower show I have ever attended. If the Magnolia Garden Club stages the event next year, prior to the event, I will describe what makes the flower show so different than any others that I have attended. This is a flower show you don’t want to miss.
One of the vendors selling plants at the event was Growing Old Nursery. The relatively new nursery is located between LaGrange and Columbus. While the owners grow and sell a wide variety of plants they specialize in heirloom flowers and vegetables, and native plants.
My wife and I bought a number of plants from them including native azaleas, butterfly weed, touch-me-nots and hollyhocks. I have found it hard to find hollyhocks that produce single flowers. Invariably when I locate hollyhock seeds or plants they are double-flowered varieties. The ruby-throated hummingbird and other pollinators prefer feeding on hollyhocks that display single flowers.

Currently, scores of species of songbirds are migrating northward. Many of these birds will pass over and even stop in our backyards. However, since many of these birds rarely visit feeders, they are often only seen by those among us that have time have learned their vocalizations and take the time to scan the bushes and treetops surrounding their homes looking for these magical birds. There is, however, another way that you can catch a glimpse of these often rarely seen birds; they can be attracted with moving water.
Although many of these birds will visit a birdbath, those birdbaths that are equipped with a mister or dripper are far more likely to attract these long-distance migrants. The reason for this is the sight and sound of moving water act as a magnet to both resident and migrant birds alike.
Some of the simplest ways to create moving water range from hanging a hose of a limb and allow the hose to slowly drip water into a birdbath or pan. You can also punch a small hole in the bottom of a bucket or soft drink container full of water and hang it above a birdbath.
I personally have had better success in attracting birds to my birdbath using misters and drippers. The best misters and drippers are engineered specifically for birds use. They vary widely in price and design. While they all work, the ones that I prefer permit me to adjust the flow of the water passing through them. I often use this feature to adjust the nozzles so that they emit both a mist and water droplets. This creates ripples when the droplets fall onto the surface of the water below. When it is windy the mist is often blown away from the birdbath. When this occurs, I simply adjust my mister nozzle so that it emits only droplets.
If you want to catch a glimpse at some of the warblers, tanagers, vireos and other songbirds that may be stopping in your yard, go ahead and install a mister. Even after the migration has passed, a mister will help attract backyard residents throughout the entire year.
These devices are readily available at stores that specialize in birding supplies.
