Eastern Bluebirds: A Wisconsin Conservation Success

The Eastern Bluebird, a bird that symbolizes hope and renewal, is a welcome sight for Wisconsin residents and visitors alike, especially in the early spring. Bluebirds are secondary cavity nesters; these birds often rely on human assistance through managed bluebird trails and nest box monitoring programs, because bluebirds don’t excavate their own nesting cavities. The efforts of citizen scientists in Wisconsin, collaborating with organizations such as the Wisconsin Bluebird Association, have helped in the species’ recovery from significant population declines in the past; this collaboration resulted in a thriving bluebird population. Bluebirds enhance Wisconsin’s natural beauty and provide a tangible connection to the environment through their presence.

Welcome the Eastern Bluebird to Your Wisconsin Yard!

Hey there, fellow Wisconsinites! Ever seen a flash of brilliant blue flitting around your yard and wondered what it was?

We’re going to cover everything you need to know, from setting up the perfect nesting box to offering them a delicious buffet of insects and berries. We’ll even talk about how to protect these little guys from predators and other dangers. So get ready to roll up your sleeves and become a Bluebird buddy! Together, we can ensure these amazing birds continue to thrive in our beloved Wisconsin.

Meet the Eastern Bluebird: Your Wisconsin Backyard Buddy!

Okay, let’s get to know our beautiful blue-feathered friend! It’s super important to be able to spot an Eastern Bluebird when you see one, and trust me, you’ll want to see one!

So, what does this little gem look like? They’re not huge, about 6-8 inches long – think robin-sized, but way cooler colors. The males are the showstoppers, rocking a vibrant, almost unbelievably blue back and head, with a warm, rusty-red breast. Ladies are a bit more subtle, with a grayish-blue back and a softer orange breast. Keep an eye out for their white bellies, a neat finishing touch to their fit!

And the sounds they make! Forget jarring squawks, bluebirds sing a sweet, warbling song – a soft “cheer-ful, cheer-ly”. You might also hear a simple “tru-ly” call. They’re not just pretty faces; these birds are pretty polite, too! As for behavior, watch them perch on fences or wires, keeping an eye out for insects. It’s like they’re saying, “Hey world, I’m beautiful and helpful!”

Diving Deep: The Bluebird Lowdown

Time for some bluebird ecology! Don’t worry, it’s not as scary as it sounds. We’re just gonna peek into their daily lives, Wisconsin style!

Bluebird Diet: From Bugs to Berries

These little guys are insectivores with a side of fruit-arian! In spring and summer, they’re all about the bugs – juicy mealworms, crickets, grasshoppers… basically, anything that hops or crawls (that’s why they’re welcomed guests). Mealworms are easy to find and serve! As the weather cools, they switch to berries, like serviceberries, blueberries, and dogwood berries, which are really important for surviving those cold Wisconsin winters. It’s like they’re switching from burgers to smoothies – gotta stay healthy!

Open Habitats: Room to Roam

Bluebirds are fans of open spaces with short grasses and scattered trees or shrubs. Think fields, meadows, orchards, and parks. Why? Because they need room to hunt for insects! They love perching spots like fences, posts, and low branches. The birds are on the hunt, scanning for the next meal and diving down to grab it!

Migration: To Stay or Not to Stay?

Some Wisconsin bluebirds are snowbirds, heading south for warmer weather when the temperatures drop; the weather is a significant factor. Others are tough cookies and stick around through the winter, relying on berries and whatever insects they can find. Whether they migrate depends on food availability and, of course, how harsh the winter is. It’s a bluebird gamble!

Molting: A Feather Makeover

Just like us changing wardrobes, bluebirds molt once a year, usually in late summer or early fall. This is when they lose their old, worn-out feathers and grow new, fresh ones. It’s a gradual process, so they don’t lose their ability to fly. Imagine getting a whole new outfit before winter!

Wisconsin Climate: A Balancing Act

Wisconsin’s climate definitely throws some challenges at bluebirds. Freezing temperatures, heavy snow, and ice storms can make it tough to find food and shelter. Also, climate change is starting to mess with their migration patterns and food sources. Warmer winters might seem nice, but they can also lead to fewer insects in the spring, which can affect nesting success. It’s a changing world for these little blue gems, and we need to help them adapt!

Creating the Perfect Bluebird Nesting Site: Your Bluebird Dream Home Guide!

Okay, so you’re officially on board with the Bluebird Brigade! Fantastic! Now, let’s talk real estate. Forget Zillow, we’re building the ideal bluebird Airbnb, or rather, BNB (Bluebird Nesting Box)! Providing the right kind of home is crucial for attracting these lovely birds. It’s not just about slapping a box on a post, it’s about creating a safe, cozy, and desirable haven. Think of yourself as a bluebird property developer!

Bluebird Nesting Boxes: Design Specs, Materials, Placement and Maintanence

Here’s the blueprint to becoming a bluebird-box-building boss:

• Design Specifics: Think function meets fashion…bluebird style. We’re talking dimensions! A floor size of about 5×5 inches is ideal. The entrance hole is arguably the most important thing. It must be exactly 1 ½ inches in diameter. Anything larger invites those pesky House Sparrows, which we’ll talk about soon, and anything smaller might exclude the bluebirds! Ventilation is key for temperature control, so drill some small holes near the top. Drainage holes in the floor are also a must, because nobody likes a soggy nest. So keep them well ventilated and dry.

• Materials: Wood is good! Cedar or redwood are excellent because they’re naturally weather-resistant, that will provide durability for a long time to come. Untreated pine is also a viable option, but it won’t last as long. Avoid using pressure-treated wood, as the chemicals can be harmful to our little blue residents. Remember, we’re going for natural, safe, and long-lasting.

• Placement: Location, location, location! Bluebirds love open areas with short grass, providing them easy access to snacks (bugs!). Mount your box on a post about 5 feet above the ground. Face the entrance hole away from prevailing winds. Spacing is crucial! If you’re putting up multiple boxes, space them at least 100 yards apart to avoid territorial disputes and ensure everyone has their own space. Consider visibility, too. Make sure bluebirds can easily spot the box from their favorite perches, like fences or utility lines.

• Monitoring and Maintenance: Once your bluebird condo is up, don’t just forget about it! Become a diligent landlord! Check the box weekly during nesting season to monitor progress and remove any unwanted nests, especially those of House Sparrows. After each brood fledges (leaves the nest), clean out the box to remove old nesting material and prepare it for the next family. At the end of the nesting season, give the box a thorough cleaning with hot, soapy water to eliminate any lingering parasites. And of course, inspect for and make any needed repairs.

Discouraging Nesting Competitors (and Encouraging Coexistence)

Unfortunately, our beautiful bluebirds aren’t the only birds looking for a cozy nesting spot. Managing the competition is essential for bluebird success!

• House Sparrows: These guys are the bullies of the bird world. They are non-native, highly aggressive, and will actively evict bluebirds from their nests, even killing the young! Identifying them is easy: they’re small, brown, and have a distinctive chattering call. The most effective way to control House Sparrows is through nest removal. Remove their nests daily during the nesting season and discourage them from hanging around by avoiding feeding them in your yard.

• European Starlings: Like House Sparrows, Starlings are also non-native and highly competitive. They are larger than bluebirds and can easily take over a nesting box. Starlings are easily identified by their glossy black plumage and long beaks. Since they prefer larger cavities, using a 1 ½ inch entrance hole will often deter them. If they do manage to nest, remove their nests promptly.

• Tree Swallows: Unlike the previous two, Tree Swallows are native and generally don’t pose a direct threat to bluebirds. In fact, they often coexist peacefully. However, they will compete for nesting sites. The best strategy is to provide multiple nesting boxes, spaced about 25 feet apart. This allows both bluebirds and Tree Swallows to nest successfully in the same area.

• Other Competitors: Chickadees and Wrens may also occasionally attempt to nest in bluebird boxes. While not as aggressive as House Sparrows or Starlings, they can still displace bluebirds. Monitor the boxes regularly and remove their nests if necessary. Generally, these species prefer nesting boxes with smaller entrance holes, so maintaining the correct hole size for bluebirds will help.

Protecting Bluebirds: Being a Guardian Angel (Without the Wings)

Okay, so you’ve enticed these beautiful blue fellas to your yard. Now comes the slightly less glamorous, but super important, part: keeping them safe! Think of yourself as a bluebird bodyguard, ready to ward off anything that might harm them. Wisconsin has its share of critters, creepy crawlies, and, unfortunately, chemicals that can threaten these little guys. Let’s dive into how we can minimize those risks!

Evicting the Bad Guys: Predator Patrol

Wisconsin wildlife is amazing… until it’s eyeing up your bluebird family. Raccoons, snakes, even the neighbor’s cat can pose a serious threat.

• The Usual Suspects: We’re talking raccoons (those masked bandits!), snakes (yikes!), free-roaming cats (yes, Fluffy can be a menace), and even squirrels (who knew they were so ambitious?). Other birds of prey can also be a threat.
• Fort Knox for Bluebirds: Predator guards are your best friend. These are physical barriers you attach to the nesting box pole to prevent predators from climbing up. There are various designs, but cone-shaped or stovepipe guards are popular and effective.
• Cat Curfew: If you are a cat owner, the best thing you can do is to keep your feline friend indoors. This protects not only bluebirds, but all the wonderful wildlife that shares our space.

Battling the Bugs (and Other Nasties): Disease and Parasite Defense

Sometimes, the enemy is tiny and invisible. Bluebirds can be susceptible to diseases and parasites.

• The Unwelcome Guests: Blowflies are a common nuisance. Their larvae can infest nests and harm baby birds. Mites are another itchy problem.
• Cleanliness is Next to Bluebirdliness: The best defense is a good offense: keep those nesting boxes sparkling! Clean them out after each brood fledges. Remove old nesting material. A little bleach solution (followed by a thorough rinse and drying) can do wonders.
• When to Call the Pros: If you suspect a serious disease or parasite infestation, don’t play doctor! Contact a local wildlife rehabilitator. They have the expertise to diagnose and treat sick or injured birds.

Chemical Warfare? No Thanks!

Insecticides and pesticides might seem like a quick fix for garden pests, but they can have devastating consequences for bluebirds. Remember, these birds rely heavily on insects for food, especially when raising their young.

• Poisoned Plates: Insecticides kill off the very insects bluebirds need to survive. The chemicals can also directly poison bluebirds if they ingest contaminated insects.
• Go Organic (or at Least IPM): Embrace organic gardening practices. Attract beneficial insects that prey on pests. Consider integrated pest management (IPM) techniques, which focus on minimizing pesticide use.
• Think Before You Spray: If you must use pesticides, choose targeted options that are less harmful to birds and other beneficial insects. Always follow the instructions carefully and avoid spraying when bluebirds are actively foraging.

Supporting Thriving Bluebird Populations

Alright, you’ve provided a cozy home and kept the riff-raff (ahem, House Sparrows) away. Now, let’s supercharge your efforts and turn your yard into a bluebird paradise! Think of it as becoming a bluebird booster, a feathered friend facilitator, or even…a Bluebird Buddy! (Okay, I’ll stop with the alliteration.) Here’s how you can go the extra mile:

Bluebird Trails: The Scenic Route for Sky-Blue Sweeties

Ever heard of a bluebird trail? It’s not just a path bluebirds use; it’s a series of nesting boxes strategically placed to provide ample housing for these lovely birds. Imagine a real estate boom, but for bluebirds! These trails create connected habitats, allowing bluebirds to thrive and expand their populations.

Getting Involved:

• Start Your Own: Space nesting boxes approximately 100-300 yards apart in suitable habitats (open areas with perches). Keep records of nesting activity.
• Join an Existing Trail: Hook up with other bluebird enthusiasts. Wisconsin is likely to have local bluebird organizations running trails near you.

It’s all about safety in numbers and a supportive community. Plus, you get to hike around and check on cute baby birds!

Planting Native Plants: Bluebird Buffet Time!

Imagine having a garden stocked with bluebird delicacies. Forget boring birdseed – we’re talking gourmet berry buffets! Native plants offer the most nutritious and readily available food sources for bluebirds throughout the year.

Wisconsin Favorites:

• Serviceberries: Early-season berries.
• Dogwood: Late summer to fall fruits.
• Blueberries: A Wisconsin classic.
• Viburnums: Many species are native.

Plant a variety to ensure a steady supply throughout the seasons! Think of it as designing the perfect Bluebird Bistro!

Providing Water Sources: Keeping Them Hydrated and Happy

Even birds get thirsty! Providing a reliable water source is crucial, especially during the hot summer months. Think beyond a simple birdbath.

Watering Hole Options:

• Bird Baths: Easy to clean and refill.
• Ponds: A natural and attractive option (if you have the space).
• Streams: A naturally flowing water source is ideal.

Important Note: Keep water sources clean to prevent the spread of disease. Regularly scrub bird baths and consider using bird-safe cleaning solutions. Algae growth is never a good look for your establishment!

Understanding Fledglings: Leave Them Be!

So, you’ve found a baby bluebird hopping around on the ground. What do you do? RESIST THE URGE TO RESCUE!

Fledglings (young birds that have recently left the nest) often spend a few days on the ground while learning to fly. Their parents are usually nearby, still feeding and protecting them. Moving a fledgling can actually do more harm than good.

What to Do:

• Observe from a distance: Make sure the bird is truly injured or abandoned before intervening.
• If in immediate danger: Gently move the bird to a nearby bush or tree branch.
• If injured: Contact a licensed wildlife rehabilitator.

Spread the Word: Educate your friends, family, and neighbors about bluebird conservation. The more people who understand and support bluebirds, the brighter their future will be! Let’s make everyone a Bluebird Believer!
