SWEETSHRUB IS A FRAGRANT ADDITION TO YOUR YARD

     I am surprised that more Georgians are not familiar with the sweetshrub (Calycanthus floridus).   Since it bears some of the most fragrant blossoms of any of our native woodland shrubs, you would think that most folks would want it growing in their yard.

     The sweetshrub’s blossoms are maroon in color and produce a pleasing aroma that my wife and I are convinced smells like apples. However, some describe the scent as smelling like spicy strawberries.  Others inhale the shrub’s pleasing aroma and say it reminds them of a mixture of pineapples and bananas.

     Regardless of how you interpret the pleasing odor, the vast majority of us love it.  In fact, some people think so highly of it they plant sweetshrubs near their outside doors.  This allows them to lean over and take a whiff of the flowers before heading out for the day.

     The sweetshrub is also a pollinator plant.  Although Sweetshrub blooms generate pollen used by native bees and butterflies, sap beetles are the plant’s main pollinator.  However, since sap beetles are small (1.4-inch) and nondescript we often overlook them.

 

     The way in which these beetles pollinate sweetshrub blossoms in a little strange.  The fragrant flowers draw the beetles with the scent they emit.  Once the beetles land on the blossoms, they crawl down inside the bloom and begin gathering pollen. Here is where this gets odd.  When the beetles are ready to leave, they have a difficult time exiting the flower. As such, they often remain there until the flower matures enough for its petals to fold back enough for them to depart.  Once they are on the wing, they fly off carrying granules of pollen.  When they land on another sweetshrub blossom, they inadvertently pollenate that flower.

     Sweetshrub is easy to grow from seed, transplants, and cuttings.  While there are cultivars on the market, I have never planted any of them. If you want to be sure you are planting sweetshrubs that produce beautiful maroon blooms, a pleasing apple scent, and pollen relished by pollinators; you cannot go wrong buying plants from reputable nurseries that deal in native plants.

HOW MUCH ARE WE SPENDING ON BIRDSEED AND FEEDERS?

        Few of us keep records of how much we spend annually on wild birdseed and feeders.  However, the Wild Bird Feeding Industry Research Foundation closely monitors our bird feeding habits.

       According to their 2015 report on our purchasing activity, the average American household that feeds birds annually spends an average of $59.73 on food and $39.52 on feeders.

       Although I do not keep a record of my bird feeding expenditures, I am confident I spend much more than this.  How much are you spending on this pastime?

LIST OF NON-NATIVE INVASIVE PLANTS IS A VALUABLE PUBLICATION FOR ALL GEORGIA HOMEOWNERS

       One of the biggest threats to Georgia’s native plants and animals is the spread of exotic plants. Many are capable of destroying native plant and animal communities.

       One way these damaging plants get a foothold is by being planted in backyards across the state.  With this in mind, the Georgia Exotic Plant Council has developed a list of these damaging plants. This valuable publication is available online.  All you have to do to access the list is to Google: List of Non-Native Plants of Georgia.

       If you are concerned about the future of Georgia’s diverse and valuable native plant and animal resources, I urge to you to download this publication today.

BACKYARD SECRET—CHIMNEY SWIFTS CANNOT PERCH ON UTILITY WIRES

       If you ever spot a chimney swift perched on an electrical or telephone line, stop whatever you are doing and take a picture of it.  Your photo would be rare indeed.  This is because ornithologists believe these small birds are incapable of perching in such locations.

       This might seem odd since we routinely see mockingbirds, mourning doves, sparrows, red-shouldered hawks, sparrows, and many other birds perched on the wire.  The reason they are able to perch in such places is the structure of their feet and legs are very different from those of the chimney swift. 

       Instead, the chimney swift’s toes, nails, and legs are suited to cling to vertical surfaces such as upright trunks of trees, walls and the interior surfaces of chimneys.

LOOK FOR LEOPARDS IN YOUR BACKYARD

        From spring into fall, leopards stalk our backyards.  I am not talking about the feline variety.  I am referring to the giant leopard moth (Hypercompe scribonia).

        However, like the predator, that roams the wilds of Asia and Africa, the giant leopard moth also has spots.  The spots on its wings vary from black to blue.  Some spots might even have white centers.  Once you see one, you will have no problem understanding why we call it the leopard moth.  Nevertheless, I think you will agree with me that it would have been more appropriate to name it the Dalmatian moth.

       The female leopard moth is smaller than the male. Males have a wingspan of 3.6 inches whereas the female’s wingspan is only 2.25 inches.

       The leopard moth has a variety of host plants including male, cherry, willow, sunflower, cabbage.

       If you want to see one of these handsome moths, the best strategy you can employ is to have the moth come to you.  Fortunately, leopard moths are attracted to lights.  Armed with that tidbit of information, just pull up a lawn chair near an outside light and wait.  (Lights with shorter wavelengths work best.)  If there is a giant leopard moth nearby there is a good chance it will appear.

       When a leopard moth finally shows up chances are will be a male.  For some reason, females do not visit lights as often as the males. 

       As you might expect, some folks will attract more leopard moths than others will.  I have never been able to attract more than one leopard moth at a time to my lights, nevertheless, some homeowners report seeing upwards of a dozen or more.

          

BLOGGER REPORTS GOLDFINCHES LOVE ANISE HYSSOP

       One of the many things I enjoy about blogging is fellow bloggers are often willing to share their wildlife experiences and gardening tips.  Recently blogger Heather N. graciously revealed one of her wildlife gardening tips.

       Heather wrote that each summer one of the plants that goldfinches are drawn to in her yard is anise hyssop (Agastache foeniculum).  She went on to say that these beautiful birds are eating anise hyssop seeds right now.

       Since I am not familiar with the plant, I decided to do a little research on it.  I found that it is native to the northern section of the United States and Canada.  However, this perennial herb is widely planted in many parts of the country, including Georgia.

       The plant produces blooms that attract a number of pollinators such as butterflies, bees and hummingbirds. Its leaves produce a pleasant licorice scent.  Its seeds are also consumed by a number of birds, like goldfinches.

       If Heather had not taken the time to share her wildlife gardening tip, I might not have ever learned of anise hyssop’s value to wildlife. Now that I am aware of it, I hope to find a place for it in my yard.

Thanks Heather!

BREAKING NEWS – HUMMINGBIRDS DO HAVE A SENSE OF SMELL

        We have long been aware that hummingbirds have great eyesight and hearing.  However, biologists have unable to demonstrate that hummingbirds could smell.  However, recent studies conducted by researchers at the University of California Riverside have revealed for the first time that hummingbirds can smell insects that pose a danger to them while they are visiting flowers bearing nectar.  The findings also suggest that this ability helps them avoid danger while feeding.

       According to Erin Wilson Rankin, associate entomology professor and coauthor author of the paper that was published in   the journal Behavioral Ecology and Sociobiology, “This is pretty exciting, as it is the first clear demonstration of hummingbirds using their sense of smell alone to make foraging decisions and avoid contact with potentially dangerous insects at a flower or feeder.”

       The experiment was deceptively simple.  They provided more than 100 hummingbirds the option of feeding at two feeders.  One feeder contained sugar water and another filled with sugar water and additives that indicated that an insect was present.  One additive was formic acid which is produced by some Formica ants.  This chemical is known to be harmful to humans and mammals alike. The other was an ant attraction chemical. Another chemical tested was a chemical left behind when a European honeybee visits flowers. 

       The hummingbirds seemed oblivious to the honeybee-generated chemical.  However, the birds avoided food laced with both of the ant-based chemicals.

       Since all of the feeders were identical, the only way that the birds could differentiate between the feeders was through their sense of smell.

       It seems like every few years we learn something new and fascinating about hummingbirds.  As such, it begs the question, “What will researchers discover next about these amazing birds?”

THE DANGER POSED BY COPPERHEADS IN GEORGIA YARDS

       The chances of finding a poisonous snake in a Georgia backyard are low.  However, if one does appear, throughout most of the state, it will be a copperhead. One reason for this is the snake is ranges throughout the Peach State except in that portion of the southeastern Coastal Plain below the Altamaha River.  Another reason is copperheads appear to be more tolerant of human development than other species of poisonous snakes.

       While nobody ever wants to find a poisonous snake in their yard, if one does appear, probably the one that you want to see is the copperhead.  It is not an aggressive snake.  As such, more often than not, copperheads will only strike when they are disturbed or folks try to pick them up.

       Unfortunately, copperheads do bite humans. An average of 2,920 copperhead bites occurs annually. The good news is, since copperhead venom is the least potent of any poisonous snake found in North America, copperhead bites are rarely life-threatening.  In fact, only 0.01 percent of these bites are fatal.

 

 

FEEDING NYGER SEED IN SUMMER

       Although nyger seed is fed to birds throughout all seasons, many backyard bird feeding enthusiasts shy away from offering the tiny, black seeds to their feathered dining patrons during the summer. Is there some basis for this concern?  Most definitely, however, here is how and why I do.

       Nyger seeds are typically relished by a small number of the birds that visit our feeders.  American goldfinches and pine siskins are especially fond of them.  Other birds that consume nyger seeds are mourning doves, purple and house finches, dark-eyed juncos and indigo buntings, to name a few.  However, during the summer, in my yard, the vast majority of the nyger seeds are eaten by American goldfinches. 

       That is fine with me, since I would rarely have a chance to regularly enjoy gazing across my yard at splendor of a male goldfinch in full breeding plumage if they did not come to my feeders to feed.  To me, it is worth the money I spend on nyger seed to enjoy this pleasure. As anybody that feeds birds knows, nyger is the most expensive seed we offer in our feeders.

       The reason for this is it is raised overseas.  Most of the 70 million pounds of it that is imported into the United States is raised in India and Ethiopia.  The cost of shipping the seed that far jacks up the price.  On top of that, the United States Department of Agriculture requires that all nyger seed undergo costly heat sterilization.  This is done in attempt to keep potential invasive weeds that might contaminate the nyger seeds from entering the United States.  As a result, we can pay $60 or more for a 20-pound sack of nyger seed.  This is definitely not a seed you want to waste.

       Since nyger seed contains 40 percent fat, it spoils easily. In addition, nyger seeds have very thin coats.  With that in mind, they can spoil in the matter of a few days in the hot summer sun.

       Consequently, during the summer I fill my nyger seed feeders with a small amount of seed. I also store nyger seed in a cool place. If I have room in my freezer, I will often store it there.  

       I also buy small amounts of the seed.  The reason for this is once it becomes rancid the birds shy away from it.

       The bottom line is throughout the summer the birds will dine on nyger seed in your backyard can get along very nicely without it.  If, however, you live within the American goldfinch’s breeding range in Georgia (throughout the state except in the southeastern counties), and you want to enhance your chances of seeing American goldfinches when they are most beautiful, nyger just might help you accomplish that goal.
