Give bluebirds a hand as they scout for nesting locations

Photo by Matthew Saulsbury/Pixabay • Bluebirds are likely already scouting for nesting cavities and nest boxes in the region.

It’s time to turn the calendar page to February and, depending on the prognostication of the groundhog, winter may or may not be on the wane. Regardless, some of our feather friends are already acting like spring has sprung.
Perhaps it’s simply confusion when days can veer from sunny, short-sleeve conditions to frigid snowstorms, but I tend to trust the instincts of our fine feathered friends.

An email from Unicoi County resident Amanda Austwick proved timely.
“I saw a post on Facebook from a woman in Ontario, Canada, and she had a photo of a bluebird in a tree surrounded by red berries, with a touch of snow on them,” Amanda wrote. “I thought bluebirds migrated south in winter.”

I responded to Amanda’s email and will share some information in this week’s column. For the most part, local bluebirds do not migrate out of the region in winter. Bluebirds living farther north do often, but not always, migrate farther south.
As I mentioned to Amanda, I notice bluebirds almost daily on my drive from home to work. On sunny mornings, male Eastern bluebirds are producing their enthusiastic, warbling song even if there’s been a touch of frost overnight.

The Eastern bluebird is one of North America’s best-known cavity-nesting birds. About 85 species of North American birds use cavities in trees for nesting purposes. Cavity-nesting birds include ducks, such as buffleheads and wood ducks, as well as birds of prey such as Eastern screech-owls and American kestrels. Woodpeckers and nuthatches can excavate their own cavity in a dead or decaying tree.

Others, such as the bluebirds, must find a cavity already in existence. Such cavities are scarce real estate and can be subject to some intense competition.
The Eastern bluebird is at a disadvantage when forced to compete with non-native introduced birds such as aggressive European starlings and house sparrows. Even native competitors such as house wrens and tree swallows are serious rivals when it comes down to staking a claim to prime nesting sites.

Over the years, I have found bluebirds nesting in cavities inside wooden fence posts, but there are fewer wooden fence posts every year. This reinforces the idea of how changing landscapes have affected these birds. Instead of wooden fence posts, many farmers now use metal ones, and dead or dying trees — a much sought-after resource for cavity-nesting birds — are often removed from woodlands. Winter storms this season, along with accompanying high winds, have brought down numerous trees in the woodlands around my home, no doubt removing some current or future nesting possibilities.

When it comes to choosing a nesting cavity, male bluebirds take the lead, investigating and exploring potential sites before introducing females to the chosen real estate. If she accepts his choice, she will build the nest.

Cavities can also find use by bluebirds for secure locations for roosting overnight. According to the website Tennessee Watchable Wildlife, observers have documented bluebirds using nest boxes to stay warm during cold winter nights, packing eight to 12 individuals into one box. With the generated body heat from all those birds, I imagine that was one cozy box!

The website also noted that the oldest known Eastern bluebird in the wild reached an age of 10 years and six months. Given that most songbird live fairly short lives, that was quite an achievement.

For those interested in becoming bluebird landlords, check out nest box designs at the Tennessee Watchable Wildlife website. Several different nest box designs are available at the profile for the Eastern bluebird at tnwatchablewildlife.org.
If you’re not a do-it-yourself individuals, most lawn and garden centers, farm supply stores and speciality bird shops carry readymade bluebird boxes for purchase.
In addition to housing, food and water can be used to lure Eastern bluebirds closer. This bird doesn’t eat seeds, but it can be attracted with an offering of mealworms — live or freeze-dried – or commercially prepared peanut butter nuggets. A water feature in a yard is also a magnet for bluebirds and a host of other bird species.

Observant people have probably noticed Eastern bluebirds already checking out possible nesting locations. These cavity-nesting birds begin scouting for possible nest sites in February and March. By April, female bluebirds may be incubating a clutch of eggs.

Although bluebirds will nest in natural cavities in trees, they respond readily to the availability of nesting boxes provided by human landlords. Many people are devoted to the cause of seeing that bluebirds — a favorite of many — continue to thrive in the face of certain challenges.

Eighteen-year-old Adrianna Nelson is one such person. A senior at John S. Battle High School, Adrianna said she recently became involved with the Tennessee Bluebird Society as a way to become active with a conservation-related activity involving birds.

“I only recently got involved with TBS,” she said.

She began looking last summer for a way to contribute locally to the welfare of birds.

“I came across the TBS website,” she said. “They didn’t have a coordinator for Sullivan County, so I decided to fill the position.”

Nelson said she is interested in all birds but enjoys focusing on bluebirds and other cavity nesters to spread knowledge about their importance.

“TBS focuses on bluebirds,” she said.

Bluebird-FencePost

Bluebirds are like the “poster child” for the organization, Nelson noted, but she also pointed out that TBS also promotes the conservation of other native cavity nesters.

As county coordinator for TBS, her job primarily involves giving presentations to raise awareness about bluebirds and other cavity-nesting bird species.

“I have already presented to the Bristol Bird Club, and I plan to still give a few more presentations,” she said.

“I can also set up bluebird trails,” Nelson said. “I have not done any trails this year, but I have plans for next year. Part of my responsibilities is also to maintain trails and answer questions from the community.”

 

There are some good reasons for people to offer extra support to help bluebirds thrive.

“Eastern bluebirds are native cavity nesters,” Nelson said. “They are not strong enough to excavate their own cavities, so starlings and house sparrows can take over natural and man-made structures very quickly. It is important to promote the longevity of native species. Not only are they important, they are very beautiful.”

There are several things that people can do to make their yards and gardens more attractive to bluebirds.

“One of the most important is to make sure that there is proper habitat,” Nelson explained. “Bluebirds prefer open areas with some trees or other perches for spotting insects.”

For those interested in attracting nesters, Nelson said that picking the right nest box and proper placement is important.

She helps maintain nesting boxes along a bluebird trail at Steele Creek Park in Bristol.

In addition, providing plenty of water helps. “Bluebirds also like meal worms, but plants such as dogwoods, sumac, pokeweed, viburnum, and others can provide food, especially in the winter,” Nelson said.

Keeping predators away is crucial. According to Nelson, this can be achieved with simple actions such as keeping cats indoors.

“There are more details about bluebirds, boxes, nesting, predators, habitat and more online on the North American Bluebird Society website,” Nelson added.

Nelson shared some fascinating facts about bluebirds.

“They can spot insects from over 50 yards away,” she said.

Bluebirds are bigger than small songbirds like chickadees, wrens and warblers, yet they weigh only about one ounce.

Bluebirds are truly “early birds,” according to Nelson. “Eggs usually hatch within the first two hours after dawn,” she said.

There are no local meetings of the Tennessee Bluebird Society, but an annual meeting for TBS is held in November. The meeting is open to the public.

TBS and North American Bluebird Society members get quarterly journals and newsletters. There is also information on the websites of the two organizations for anyone interested in bluebirds.md19917207443

NABS was founded in 1978 by Dr. Lawrence Zeleny in order to promote the preservation of bluebirds, a cavity-nesting species in decline at that time. Zeleny, with the support of his wife, Olive, dedicated much of his life to providing nestboxes and managing bluebird trails. He promoted bluebird conservation through hundreds of talks and articles in many periodicals.

The Eastern bluebird has two close relatives — the Western bluebird and the mountain bluebird. These species belong to the genus, Sialia, which is counted among the world’s thrushes.The Western bluebird ranges throughout California, the southern Rocky Mountains, Arizona and New Mexico. The mountain bluebird is widespread in the western United States, as well. Two states — Idaho and Nevada — have bestowed official status on the mountain bluebird as their official state bird. The Eastern bluebird has also been honored with that designation by the states of Missouri and New York.

The Eastern bluebird suffered serious decline from 1940 into the 1960s, but it is now a common bird in the region. Rick Knight, author of The Birds of Northeast Tennessee, notes that nest boxes were instrumental in the recovery of the Eastern bluebird.

Nelson is continuing the work pioneered by others to conserve the Eastern bluebird. She lives in Bristol, Virginia, with her parents, Sandi and Shawn Nelson. She welcomes the public to contact her about bluebirds by emailing adriannan1@hotmail.com.

A famous song declares that “somewhere over the rainbow, bluebirds fly,” so you’ll have to excuse me if I have been looking for those elusive rainbows during the unseasonably warm weather the region’s enjoyed in recent weeks.

Also, like the song promises, “dreams really do come true,” which was fulfilled by the arrival of this year’s first pair of Eastern bluebirds at my home on Friday, Feb. 23. The presence of a pair of these beautiful and trusting birds is always sure to put people in a good mood. People have known for generations that bluebirds make good neighbors. A pair of bluebirds in your yard or garden provides hour upon hour of free entertainment as one watches these birds go about their daily routine. At this time of the year, much of that routine is focused on finding and claiming the best possible nesting location for the upcoming spring season.

Fortunately for bluebirds, this species will also accept lodging in a nest box, or birdhouse, provided for them by human landlords. One of the simplest ways to bring bluebirds close is to offer wooden boxes, constructed to their specific requirements, for their use as nesting locations. Because of their trusting nature when it comes to their human neighbors, the Eastern bluebird is one of our most beloved birds. In fact, bluebirds are such popular birds that interest in them and their well-being has inspired the foundation of organizations such as the North American Bluebird Society. The Eastern bluebird has also been designated the official state bird for New York and Missouri, which provides more testimony to the immense popularity of this bird.

Bluebirds-One

There are two other species of bluebirds found in North America. The Western bluebird is found throughout the year in California, the southern Rocky Mountains, Arizona and New Mexico, as well as in part of Mexico. The species ranges in the summer as far north as the Pacific Northwest, British Columbia and Montana. The Mountain bluebird nests in open country in the western United States as far north as Alaska. They are short-distance migrants, retreating as far south as Mexico during the winter season.

Other than these three species, North America offers few others birds with mostly “blue” plumages. Some examples include indigo bunting, blue grosbeak, and blue jay, as well as birds like great blue heron and belted kingfisher.

In addition to housing, food and water can be used to lure Eastern bluebirds closer. This bird doesn’t eat seeds, but it can be attracted with an offering of mealworms — live or freeze-dried – or commercially prepared peanut butter nuggets. A water feature in a yard is also a magnet for bluebirds and a host of other bird species.

If your home doesn’t provide suitable open, spacious bluebird habitat, it’s still easy to enjoy these beautiful birds. An afternoon or evening drive into open country, such as agricultural farmland, is likely to yield sightings of this bird on fences and utility lines. Golf courses, some of which go the extra mile to accommodate bluebirds, also provide habitat for these lovely birds.

The Eastern bluebird is present in the region in all seasons and is one of our more common birds. If you’re already an experienced landlord and host for these birds, you probably already know they joys they can bring. If not, why not try to attract them closer to you? Most bluebirds in the region have already started looking for a nesting site. Many of these birds may nest two or even three times in a single season. March has only just arrived, so there’s still time to place a nest box or two on your property to get their attention.

Bluebirds make good neighbors. A pair of Eastern Bluebirds in your yard or garden will have no trouble with minor intrusions into their lives as they go about their daily routine, and the payoff for you is hours of free entertainment.

I’m pleased to report that the first of the season’s young Eastern Bluebirds have left the security of their nest box in our yard – the only home they’ve known since hatching – for the wider world of field and woodland.

As has usually been the case, I didn’t witness their departure. In the days after the fledglings departed the wooden nest box, I’ve observed them perched and waiting, impatiently usually, for their parents to arrive with caterpillars, moths or other morsels of food.

Last month, I found bluebirds nesting in a cavity in a wooden fence post that was part of an enclosure for a field. The fence post nest reinforced how changing landscapes have also affected these birds. Instead of wooden fence posts, many farmers now use metal ones. Dead or dying trees – a much sought-after resource for cavity-nesting birds — are often removed from woodlands.

There are two other species of bluebirds found in North America.

The Western Bluebird is found throughout the year in California, the southern Rocky Mountains, Arizona and New Mexico, as wells part of Mexico. The species ranges in the summer as far north as the Pacific Northwest, British Columbia and Montana.

The Mountain Bluebird nests in open country in the western United States as far north as Alaska. They are short-distance migrants, retreating as far south as Mexico during the winter season.

Except for a whitish-grayish belly, the male Mountain Bluebird is a brilliant sky blue above with paler blue on his underparts. The female looks similar if duller in her coloration.

Some people in the region mistakenly assume that Eastern Bluebirds are “mountain” bluebirds because they will reside in higher elevation open areas. The simplest way to tell the two species apart — although not necessary since the range of the Mountain Bluebirds is hundreds of miles to the west — is the reddish undersides of both sexes of the Eastern Bluebird.

The states of Nevada and Idaho have selected the Mountain Bluebird as their official state bird. I saw this species in 2006 during a trip that took me to Utah and Idaho.

Bluebirds are members of the extended family of thrushes, making them relatives of such birds as American Robin, Wood Thrush and Veery. The relationship of the Eastern Bluebird to the American Robin can be seen in the red breast sported by both species. In addition, young robins and bluebirds both have spotted breasts, providing more evidence of their affinity with many of the thrushes. The thrush family numbers more than 100 species worldwide and extends into Europe, Asia and Africa, as well as various islands.

Inviting the Eastern Bluebird into your yard and gardens is not usually too difficult. It helps if you live in an open, spacious habitat bordered with small trees. Providing a nesting box constructed to the specifications for this bird is another way to attract them. With natural cavities in trees and fence posts a rare commodity, this bird will readily accept boxes. It’s not a sure-fire means of bring bluebirds closer. Plenty of other native birds, including Carolina Chickadees, Tree Swallows and House Wrens, will also make use of a box designated for bluebirds.

The NABS recommends a box that is well ventilated, watertight and equipped with drainage holes. The box should also be easy to open, monitor and clean.

For more specific and very valuable information about becoming a landlord for bluebirds, please visit http://www.nabluebirdsociety.org/PDF/FAQ/NABS%20factsheet%20-%20Getting%20Started%20-%2024May12%20DRAFT.pdf to access an informative fact sheet.

Starlings and House Sparrows are not native species and are not protected by law. When present, these two introduced species will probably be your biggest challenge to successfully hosting Eastern Bluebirds. On its website, NABS encourages the control of starlings and House Sparrows. The website – http://www.sialis.org – also provides beneficial information for would-be bluebird landlords.

Tree Swallows and House Wrens, both native birds, will probably be the biggest rivals for nesting boxes intended for Eastern Bluebirds. If you should find that a pair of Tree Swallows or House Wrens has claimed a box, consider yourself fortunate and benefit from the opportunity to view the habits of these two interesting species for a few weeks.

In addition to housing, food and water can be used to lure Eastern Bluebirds closer. This bird doesn’t eat seeds, but it can be attracted with an offering of mealworms — live or freeze-dried – or commercially prepared peanut butter nuggets. A water feature in a yard is also a magnet for bluebirds and a host of other bird species.

The Eastern Bluebird is present in the region in any season and is one of our more common birds. If you’re already an experienced landlord and host for these birds, you probably already know they joys they can bring. If not, why not try to attract them closer to you? Most bluebirds in the region have already completed the first nesting of the season, but these birds are known to nest two or even three times in a single season. There’s still time to place a nest box or two on your property to get their attention.

Landscaping with fruit-bearing trees and shrubs can also pay dividends when its comes to the Eastern Bluebird. Although this bird feeds heavily on insects, almost a third of its diet consists of fruits, including blackberry, mulberry and pokeberry.

Inviting bluebirds to become a part of your life isn’t difficult, and you’ll be delighted to have them. Trust someone who has lived with bluebirds in his yard and gardens for more than 20 years.
