Although those of us that live in Georgia do not have to withstand the bitter cold that winter brings to the northern sections of the country, it still gets mighty cold in these parts.
When temperatures plummet into the 20s and below, simply trying to stay alive on a frigid winter night can be a life-threatening event for many of our wildlife neighbors. One way in which we can assist birds such as bluebirds that roost in nesting boxes survive extremely cold weather is by winterizing nesting boxes.
If you have erected a well-built nesting box, it is equipped with several 3/8″ ventilation holes drilled under the eaves of the box’s roof. These vent holes are designed to dramatically reduce the temperature inside the box in hot weather. However, during the winter vent holes allow heat to escape.
With that in mind, it is a good idea to plug these holes before the onset of winter. By so doing, you will increase the amount of heat retained in a box.
Now that most of us are getting our first taste of cold weather, there is no better time to perform this simple task than right now.
When the last threat of severely cold weather has passed next year, do not forget to unplug the vent holes.
If you have ever watched eastern meadowlarks or grasshopper sparrows singing from atop a fencepost, their bills will be wide open. However, if you take the time to watch a male eastern bluebird singing from a branch in your backyard, its beak will seem to be completely closed. The truth the matter is, if you are able to view the bird through a pair of binoculars or spotting scope you will learn that its bill is actually barely open. I think that is truly an amazing feat!
There are many superstitions surrounding Halloween. Quite a few of these folktales deal with the mistaken belief that spiders consort with witches, ghosts, and goblins. Let’s look at one of these tall tales.
One of the stories I have heard is that spiders are more abundant around Halloween because they gather with witches and unsavory characters this bizarre holiday. The truth of the matter is that chances are people are more likely to see more spiders around Halloween than they might during the spring, summer, and winter. However, this has nothing to do with Halloween. Instead, there is a scientific basis for spiders being more abundant in the fall of the year. Halloween just happens to celebrated during this season.
There are two reasons why we are more apt to see spiders in the fall. First, this is the mating season for a vast number of spiders. Consequently, spiders are more prone to be out and about then looking for mates. This increases the likelihood we will encounter them.
Another reason is when spiders emerge from eggs in spring they are extremely small; this makes them difficult to find. Throughout the spring and summer, they continue to increase in size. Once they reach maturity by fall, it is much easier for us to spot them. This gives us the false impression that they are actually more abundant.
I lament the fact that so many people cringe whenever they see a spider. As a result, untold numbers of spiders are killed because we fear them. Their perceived association with Halloween helps perpetuate our animosity toward these beneficial invertebrates. In truth, the vast majority of the 35,000 species of spiders found around the world pose no threat to humans. In contrast, they are important predators that help control insects and other invertebrates that humankind considers detrimental.
Now that our days are characterized by low humidity and cool temperatures, it finally does feel like autumn. While the weather has changed, the complexion of our gardens has been undergoing a major transformation. Those of us that try to provide wild pollinators with food throughout as much of the year as possible still have an abundance of nectar-bearing flowers in full bloom. However, alongside them are the dried seed heads of plants that bloomed earlier in the year. Although our first impulse is often to remove these plants, I wish you would consider leaving at least a portion of them for birds that feed predominantly on seeds.
The list of the flowering plants that produce seeds eaten by birds is quite long. Here is a short list of some of the more popular plants that produce nutritious seeds for birds: black-eyed susan, coneflower, cosmos, aster, scarlet sage, zinnia, coreopsis, and blanket flower.
Birds will eat these seeds directly from seed heads or when the seeds fall to the ground. In addition, it matters not whether the plants grew in containers on a deck or patio or in a traditional garden.
My wife and I have truly enjoyed watching cardinals and American goldfinches feeding on scarlet sage and zinnia seeds produced by plants grown in large containers on our deck.
It never ceases to amaze me how a cardinal can pick up a tiny scarlet sage with its large beak.
Among the birds that do not miss a chance to eat the seeds of nectar plants during the fall and winter are the northern cardinal, dark-eyed junco, chipping sparrow, and American goldfinch.
If you want to add a new facet to bird feeding, simply resist the impulse to create a tidy garden. Let the plants that produced the stunning floral display remain standing.
If you do, you will be providing your autumn/winter avian visitors with a great source of food. Meanwhile, you will enjoy watching the fascinating behavior of birds foraging for flower seeds.
Unfortunately, folktales link many of our backyard wildlife neighbors such as owls, toads, snakes, and bats to Halloween. That being the case, with Halloween only a few weeks away, there is no better time to dispel one of the tall tales regarding one of these unfortunate animals — the toad.
The animals associated with Halloween have a number of things in common. For example, many are creatures of the night. This is a time when folktales tell us these animals consort with witches and goblins. Such associations are enough to malign any animal. As such, it is not surprising that people fear the toad. Although we are not afraid toads will bite us, many people honestly believe that, if you touch a toad, you will get warts. Apparently, toads also infect witches with warts as they are often depicted with warts on their noses. Let’s do a fact check and see if this bit of folklore is actually true.
The origin of this belief was long ago lost in the mists of history. However, it is widely believed this notion originated from the fact that the skins of toads are covered with lots of oddly shaped warts. Since medical knowledge was rudimentary at that time in history, this conclusion was not disputed and took on a life of its own. Who among us has not heard our father or mother tell us not to pick up that toad, because will give your warts?
The truth of the matter is warts are caused by something called a human papillion virus. There are 150 or so viruses of this type. They most often infect humans through a cut or scratch. It has been suggested that one of the reasons children seem to develop warts more than adults is their roughhousing make them more prone to get scratches and cuts. In addition, the fact that their immune systems have not yet fully developed makes them more susceptible to many infections like warts.
I can personally attest to the fact that toads do not cause warts. When my granddaughter was a youngster, I often accompanied her on forays into the dark to see how many toads she could capture in a single night. On a good night, she might catch a dozen or more of the “warty” critters. After examining and photographing them, she released them where they were captured. During these unforgettable adventures, she never developed any warts. However, I was left with a wealth of priceless memories.
I hope that I have dispelled this folktale. Unfortunately, I suspect that the belief that toads can infect us with warts will be around for many Halloweens to come.
Whenever male rose-breasted grosbeaks magically appear at our feeders in the spring, it is difficult to mistake them for any other bird. No other birds are cloaked in striking black-and-white plumage and also display bright crimson red chevrons on their breasts. However, when they pass through Georgia in the fall, identifying them can be a challenge.
The reason for this is the adults are in their nonbreeding plumage when they arrive at our feeders. In addition, they are accompanied by adult and immature females, as well as immature males. Whereas immature females are difficult to separate from adult females, the still look pretty much alike.
Things are a bit trickier when it comes to distinguishing immature males from adult males. However, the best way to describe an adult male is that it appears to be a washed out version of an adult male in breeding plumage. In addition, there are subtle differences between adult and immature males that are often difficult to separate in the field. Immature males will look much like the females, however they will sport varying amount of a rose wash on their breasts that is buffier than the breasts of the females.
Most years I only see rose-breasted grosbeaks in the spring. However, others, like Ron Lee, entertain the birds during both seasons. Such has been the case again this year. Whereas Ron has been seeing these stunning migrants for quite some time this autumn, they have avoided my feeders.
Ron has been kind enough to share with us the accompanying photo of a male rose-breasted grosbeak. Ron took the picture taken October 10, 2020.
With time running out on their fall migration schedule I suspect Ron’s photo is the only rose-breasted grosbeak I am likely to see this autumn.
At this time of the year, both resident and migratory birds are feasting on a variety of colorful berries such as American beautyberry and pokeberries. However, have you noticed birds are not flocking to a native plant that produces one of the most colorful berries–the American Holly?
Nowadays if you peer into the foliage of an American holly, you will discover that the berries that are synonymous with winter and Christmas are still green. Even when they ripen, it will be a while before birds begin dining on these shiny red berries. In fact, in most years, American holly berries will remain on the tree well into winter and provide birds with a valuable source of food long after the last beautyberry or pokeberry has been gobbled up.
Among the reasons birds do not seek out holly berries when they first ripen is they are rock-hard and very bitter. It is only after the berries have been exposed to one or more frosts do they begin to soften up. Their exposure to cold weather also breaks down the chemicals that make the so bitter. Even then, they are not considered a choice food. American holly berries are not rich in many nutrients, although they are high in fats and oils.
However, when birds have little else to eat, they will dine on dine on holly berries. For birds that rely heavily on fruits and berries, holly berries can mean the difference between life and death.
A woman in Walton County once told me that, in winter, she often decorates her window boxes with branches of American holly covered with its showy red berries. She went on the say that one-winter birds did not eat a single berry the entire winter. However, one extremely cold March day a flock of robins descended on her yard. Before the flock departed, the birds had eaten every single berry that had adorned the holly boughs placed in her window boxes.
In addition to the American robin, among the more than two dozen species of birds that eat American holly berries are the northern cardinal, eastern bluebird, northern mockingbird, wild turkey, and northern bobwhite.
This is just another example of the fact that we need to provide a wide variety of plants that provide food and cover for birds throughout the entire year.
Shortly many of us will be faced with removing fallen autumn leaves from our yards. According to an article that recently appeared the National Wildlife Federation’s magazine, National Wildlife, how you dispose of these leaves can have a significant impact on the number of blacklegged ticks that will infest your yard next spring.
Three ticks that are of great concern to Georgians are the lone star, American dog and blacklegged.
According to the piece, a study conducted by the Monmouth County, New Jersey Mosquito Control Division, revealed that homeowners that raked or blew the leaves from their yards into nearby wooded areas each fall actually promoted the blacklegged tick population in their yards. It seems that the following year the blacklegged tick population was three times greater than that found in their yards the previous year.
This is significant since blacklegged ticks carry tick-borne diseases such as Lyme’s disease.
A better way to deal with the leaves is to either compost them, or use them to create or enhance wildlife habitat in an ill-kept section of your property. In garden situations, leaving leaves on the ground helps valuable insects overwinter and creates feeding habitats for wintering birds.
Currently throughout much of the state, there are few, if any, signs that fall is ready to blanket Georgia with a quilt of reds, oranges, and yellows. However, those of us that have strawberry bush (Euonymus americana) growing in their backyards have been granted a preview of the colorful show yet to come.
The strawberry bush is not a plant you would ever suspect as standing out among scores of other native shrubs that grow across the state. It is small (4-8 feet tall), often grows under the canopy of larger hardwood trees, or among a myriad of brushy plants along forest edges or in recently harvested timber tracts. However, from late summer into fall it is transformed into a shrub of unparalleled beauty.
At that of the year the plant’s seed capsules (arils), which are covered with conical warts, resemble green strawberries, turn pink and then bright red. Thereafter the leathery capsules magically open and display shiny red berries that appear suspended on thin threads. Once you cast your eyes on them for the first time, I am sure you will agree they possess unrivaled beauty.
The opened pods and dangling berries, reveals where the plant got some of its nicknames such as hearts-a-bustin, bursting hearts or hearts-bursting-open-with-love.
Strawberry bush is also referred to as spindletree. It seems that the plant’s hard wood was once used to make spindles for spinning wheels. If you will recall, in the popular children’s story of Sleeping beauty, the fair maiden fell asleep when she pricked her finger on a sharp spindle. It is believed this relates to the folktale that claims that the wood of the strawberry bush is poisonous and, if a person ingests the wood; he or she will fall into a coma. While I cannot attest that eating the wood would cause a person to end up in a coma, I do know that the plant is considered poisonous to humans.
Such is not the case with birds and mammals. In fact, it is an ice cream-food for white-tailed deer. Whitetails simply cannot get enough of it. In fact, one reason strawberry bush is not found in many woodlands is it has been heavily browsed by deer. It is interesting to note wildlife biologists often use the prevalence of strawberry bush as an indicator of the size of a deer herd.
Although, the berries are eaten by songbirds quail and even wild turkeys, strawberry bush rarely shows up in food habit studies. I believe this is because, in most places, very few berries are produced compared to other plants such as pokeberries, and American beautyberries.
Two things I also like about strawberry bush are that its leaves are aromatic and turn orange in the fall.
If your garden is not plagued by white-tailed deer, strawberry bush would be a great addition on your landscape. It is a Georgia native that is attractive and provides food for wildlife too.
Once you establish it, you will become one of the few people that can enjoy this harbinger of autumn long before the main show begins.
Recently I wrote about the how birds are attracted to American beautyberry. In response to this blog, one of our fellow bloggers, Elizabeth Neace, was kind enough let us know this beautiful native shrub can easily be rooted using cuttings. This is great news for anyone wanting to incorporate this native into his or her landscape.
I want to thank Elizabeth for sharing her backyard secret with us. I am sure many folks will benefit from this valuable tip.
