The Confederate rose brings spectacular beauty to yards across Georgia. However, my wife, Donna, and I have found that its showy blossoms are also used as places for bumblebees to escape the cold on chilly autumn nights.
This large multi-stemmed shrub or small tree was brought to North America in the 1600s. Since then it has been widely planted throughout the Southeast. It popularity stems from the fact that, from late summer until frost, it bears scores of white blossoms that measure up to six inches in diameter. These flowers eventually turn light pink before finally becoming rose-colored.
While my wife and I thoroughly enjoy the beauty the flowers bring to our yard, our discovery that these stunning blooms provide bumblebees with warm refuges on chilly fall nights has heightened our appreciation for the plant.
For quite some time, I had not given any thought to this interesting behavior until late one afternoon this past week. Late one afternoon I noticed that my wife, was looking deep into the one of the blossoms adorning a Confederate rose growing alongside our driveway. I walked up to find out what had caught her attention. When she said she was looking at a bumblebee that had settled in for the night deep inside a Confederate rose bloom, I peered down into the throat of the flower and spotted the insect. As we stood nearby discussing her find, a couple of other bumblebees flew into other blossoms.
When I returned to the flowers well after dark, sure enough, the bumblebees were still there awaiting morning when temperatures warmed to the point where they could utilize the muscles that control their wings and fly away.
A number of animals seek cover on chilly nights. Many birds and mammals retreat to natural cavities, nesting boxes, thick vegetation, and other places. However, I doubt that many spend cold nights nestled in cover as beautiful a Confederate rose blossom.
If you have a Confederate rose growing in your yard, before the blossoms nipped by a frost, as the sun is setting check them out. If bumblebees are still flying about in your neck of the woods, chances are one or more might be using some of gorgeous blooms for nighttime cover also.
From time to time, all backyard wildlife watchers see something that they cannot explain. For example, if gray squirrels frequently visit your feeders, chances are you will eventually spot one that appears to have lumps somewhere on its body. When this happens, it is only human nature to wonder what causes these mysterious lumps. A vast majority of the time, hidden inside each lump is the larva of a parasitic fly known as the squirrel bot fly.
Squirrel bot flies parasitize animals such as gray and fox squirrels, and rabbits. The squirrel bot fly looks much like a bumblebee. However, if you have the rare opportunity to examine one, you will see that it has one set of wings instead of two like the bumblebee.
Adult bot flies live for only two weeks or so. During this brief time, a female must lay her fertilized eggs on the branches of trees and other surfaces. If a squirrel happens by and touches an egg, it rapidly hatches and the larva tries to hitch a ride on the squirrel. The tiny larva must then make its way into the squirrel’s body via a body opening. This often occurs when a squirrel grooms itself and unwittingly swallows a bot fly larva. A larva can also gain access to the body through the bushytail’s eyes.
Once inside, the larva travels through the squirrel’s body before eventually ending up between the animal’s skin and flesh. Here it rapidly grows. As the larva increases in size, it creates a noticeable lump. Many people call these lumps warbles or wolves.
Over time, the liquid-filled lump swells. A bot larva can reach a size of 1.5-inches long and an inch wide. During this period in its life, a larva chews an exit hole in the squirrel’s skin through which it eventually wiggles out and drops to the ground.
Once on the ground it burrows into the soil and pupates. It will remain there until spring when it sheds the covering that protected it throughout the winter and emerges as an adult.
Meanwhile, once a larva leaves a squirrel, the open wound it left behind heals and any hair that was lost while the larva was living just below its skin will regrow.
Fortunately, we, as well as dogs and cats, cannot be infected by coming into contact with a squirrel parasitized by a bot fly.
The amazing drama involving the bot fly and the gray squirrel is played out in countless backyards across Georgia each year. However, I had never seen a “lumpy” squirrel in my yard until this year. Have you ever seen one in your yard? If you have, you now know the answer to a mystery that has confounded many folks for generations.
Blue jays are currently busy hoarding acorns. Whereas some birds and mammals store acorns in a single spot, such is not the case with blue jays. These handsome birds hide each acorn they gather in a separate spot throughout the territory they will occupy throughout the winter. It is hard to believe that a blue jay might bury an acorn it plucked from your lawn at a spot more than a mile away.
Since a single blue jay can hoard up to 107 acorns per day, you might wonder how in the world it remembers every spot where it has buried an acorn. The truth of the matter is it doesn’t. Studies have found that a blue jay only retrieves roughly a quarter of the acorns it stashes away each fall.
In other words, each day that a blue jay is collecting and hiding acorns it is potentially planting 75 acorns. Obviously, some of these acorns will rot; other critters will consume some of them. The rest could potentially germinate and develop into new oak trees.
One might say that blue jays are playing a key role in replanting our precious forests. Looking at it another way, a single blue jay plants vastly more trees than any of us in a week than most of us do in a lifetime.
For weeks, I have been eagerly awaiting the appearance of my first winter bird of the fall. By that, I mean the migratory birds that winter in my backyard typically arrive well before winter actually begins. Well, my wait is finally over as this week I spotted a ruby-crowned kinglet eating bird butter laced with peanuts.
I find it interesting that, although the ruby-crowned kinglet is one of the last insectivorous birds to leave its northern breeding grounds, it was the first to arrive in my yard located in Middle Georgia. I cannot help but wonder if the bird I saw will indeed winter here, or, was a migrant using my yard as a stopover to refuel before moving on southward to its winter home is south Georgia or Florida.
Since I never see more than one ruby-crowned kinglet at a time, I would like to know if only one of these tiny passerines establishes a territory in my yard each winter. Since there is evidence that these small birds set up winter territories, perhaps more kinglets actually inhabit my three acres of land than I realize. If such is the case, it could be possible that I host more than one ruby-crowned kinglet and the only one I see is the bird that claims the portion of the yard where my feeders are located.
Overwhelmingly, when a ruby-crowned kinglet makes an appearance in my bird feeding area it dines on bird butter. However, in one instance, I watched a kinglet sifting through white millet offered in a small feeder.
If you would like to attempt to attract a ruby-crowned kinglet to your yard this winter, make sure suet or bird butter are on the menu of your backyard bird cafe. Other foods known attract ruby-crowned kinglets are peanut butter, mixed seed, finely cracked nuts, peanut hearts, cornbread, and doughnuts. They will even visit hummingbird feeders from time to time.
I have never seen a ruby-crowned kinglet drink at my birdbath. However, there are numerous reports of them doing so.
If you are successful in attracting a ruby-crowned kinglet to your yard for the first time, you will quickly learn they are a joy to watch. They are full of energy and are constantly on the move. Some might even say they get tired just seeing them constantly flit about in search of food.
