We Found A Way to Thwart House Sparrows!

Frustration Yields to Creativity

Reprising the blog on thwarting House Sparrows. Here is a recap of our initial frustration and subsequent ways to encourage native birds and discourage exotics.

As we wrote earlier, hordes of House Sparrows almost made us give up feeding birds. We’d fill our feeders each morning and hope to watch juncos, cardinals, chickadees, woodpeckers, and nuthatches visit on cold winter days. Unfortunately, hordes of House Sparrows began arriving. We don’t mind feeding a few, but dozens soon devoured all the expensive seed, leaving empty feeders for native species.

Coming Up Short on “Expert Advice”

We asked bird experts what we might do to discourage House  Sparrows and tried several of their ideas. Nothing worked well, so we experimented and came up with a few tricks that seem to discourage House Sparrows to a degree yet let other species eat. Our tricks aren’t perfect and sparrows still come, but not in huge numbers.

Here’s what we did:

Altered filling time:

We noticed that cardinals, jays, chickadees, and nuthatches visited feeders in the early morning and late afternoon, but House Sparrows came more late morning and toward the middle of the day. So, we put out small amounts of seeds early in the morning and again in late afternoon. Often our feeders are empty mid-day when the house sparrows prefer to visit.

Used a different type of feeder:

Eating from platform feeder

Sparrows enjoy feeding on the ground, on horizontal tables and other flat surfaces, and from silo-type feeders with long perches and large openings. We took down our standard silo feeders and replaced them with a silo shape feeder made of hardware cloth with a quarter-inch mesh.

Used different types of feed

In our quarter-inch mesh feeder, we put a mixture of black oil sunflower seeds and hulled peanuts. Native birds seemed better able to extract the sunflower from the mesh than House Sparrows. The peanuts don’t fit through the mesh, but many native bird species peck at them through the wire and extract pieces of peanuts. House Sparrows seem less able, or willing, to do this.

We also stopped feeding cracked corn and millet on the ground. Sparrows love them.  Instead, we now toss full kernels of corn on the ground. Sparrows can’t swallow the big seeds and are unable to peck them apart. Woodpeckers, cardinals, blue jays, and nuthatches swallow or carry away the big seeds.

Put up with some House Sparrows

Our system helps deter these pesky exotic birds but is far from perfect. House Sparrows still visit and eat seeds but not as many as before we started using these tricks. Maybe they’ll work for you.

A few of you have shared.  Now Others Can Share.

Winding Pathways is eager to learn other ways to deter House Sparrows. If you have discovered something that works, please let us know.

What to Do When Spotting a “Bald-Faced Hornet” Nest?

Autumn Reveals Nature’s Wonders

Bare trees reveal a bald-faced hornet nest.

November’s wind stripped the leaves off one of our maples and revealed a big gray football-shaped bald-faced hornet nest. Although we’d walked under it all summer, we had no clue it was there.

This fall many people will discover similar “paper wasp” nests in their trees or shrubs or even tucked near a light fixture. Made of a paper-like material, the nest was really made by insects called “bald-faced hornets” that are related to other wasps, including yellow jackets.

These social wasps can attack in droves. Their sting hurts. Because their stingers are smooth, unlike honey bees, they can sting again and again.

So, what do you do when you spot a nest on a crisp fall afternoon? Leave it alone!

Life History

The insect’s life history gives the best clue on how to avoid painful stings.

Last fall the colony of 500, or so, worker wasps died as the weather cooled. The fertile queen survived by tucking herself under a rotting log somewhere to slumber through winter. Come spring she’ll make a tiny paper-like nest, usually in a tree, and lay eggs that become workers. These hard-working new insects expand the nest and forage widely.

They are omnivores eager to dine on rotting fruit, but among their favorite foods are caterpillars and adult insects. Bald-faced hornets are a gardener’s friend, removing vegetable-chomping insects.  They also sip on nectar so are good pollinators.

Aggressive or Protective?

Most sources claim they are highly aggressive, and they are if someone disturbs their nest. Several years ago, an adult neighbor spotted a nest above the doorway that the family had used all summer. He tried to knock it down and only damaged the nest. His misguided aggression unleashed an attack by dozens of upset bald-faced hornets. Stung many times, he’ll likely never again molest a nest.

We walked under and near the bald-faced hornet’s nest in our yard many times this summer and didn’t even know it was there. They didn’t attack us. Rather, they snacked on our vegetable gardens’ pests.

The lesson: leave these insects and their nest alone.

Ironically, by the time most people discover a nest in very late fall, the colony has already abandoned it. The best thing to do is NOTHING. Winter’s wind, rain, and snow will disintegrate the nest, and the queen will find a new spot to build next year’s colony.

 

Windows, Deadly for Birds

Why do Birds Fly Into Windows?

BirdStop spray clouds windows

The spray makes the window opaque.

Windows, deadly for birds. According to the National Audubon Society, about one billion birds are killed every year when they crash into windows. About half collide with low commercial building windows with the rest crashing into home windows. Surprisingly few seem to crash into the high windows of skyscrapers.

Birds fly into windows because they just don’t see them and assume they’re about to zip through safe soft air. Sometimes they may see reflections of vegetation behind them and think they are zooming to a convenient perch.

How to Help a Bird

When Rich was director of the Indian Creek Nature Center, he’d often get calls from upset people who had just found a quivering bird beneath their window. In his experience one of two outcomes is likely. Either the bird will soon die or it will fully recover and fly off. He suggests leaving the bird alone for at least an hour unless it’s likely to fall prey to a hungry neighborhood cat. In that case, it is probably best to gently place it in a cardboard box to give it a chance to recover…or die.

Unfortunately, there’s no effective first-aid technique to reverse death. Hopefully, the bird will soon recover and speed away. If not, a respectful burial is in order.

Tips

Here are some tips from the Portland, Oregon, Audubon Chapter of the National Audubon Society for reducing window collisions:

  • Place bird feeders away from large windows.
  • Avoid putting house plants immediately inside windows. Birds may see them and attempt to fly to a perch.
  • Put stickers/decals on the outside of windows. (Note: Many sources recommend these. Stickers can be bought online or at bird-feeding stores……but we, at Winding Pathways, have not found them very effective.
  • Stretch netting across the outside of the window to physically keep birds from crashing. We’ve found this best on windows that experience frequent bird collisions.
  • Put colorful tape on the outside of the windows.
  • Douse outside lights. Come sundown our nation is way over-lit. Lights block viewing the magnificent night sky while often disorienting migrating birds.

We Can Help

Songbirds face many challenges in our modern world. They crash into windows, hit poles, get gobbled up by house cats, and are confused by electric lights. They need all the human help they can get to stay alive and healthy.

 

Setting Our Yard on Fire!

On  Fire?

Many readers know we burn our yard. What? Are we nuts? Fire kills. Fire destroys. Well, it can but it also cleanses and heals.
It’s one way to manage natural growth on properties. So, on a balmy early November day, we set our yard on fire! Flames towered over the yard as intense heat pushed outward.

We usually burn smallish prairies we’ve planted in both our front and back yards. Years ago, we usually burned in March but more recently we’ve shifted to November. Burning in fall seems to encourage wildflower blooms next summer.

Preparation is the Key

We’re unusual but not reckless. (A good read is at this address. www.prairienursery.com/media/pdf/burn-your-prairie-safely.pdf.) Before burning we did these things:

  • Mowed a wide firebreak around our proposed burn area. Closely clipped lawns are nearly as effective as a firebreak as pavement or bare soil.
  • Acquired a fire permit from Linn County Public Health.
  • Found friends and neighbors to help us manage the burn.
  • Ahead of time educated neighbors about the value of burning and then alerted them of our plan to burn in a certain time frame.
  • Had appropriate tools on hand before we burned. These included garden rakes, matches, and both a portable fire pump, called a “Smith Indian”, and a hose stretched to the burn site.

Important Last-Minute Steps

On the day of our proposed burn, we did what the Health Department requires and first checked the air pollution report. We are only allowed to burn when the air quality is good, so jump online to a local map that shows real-time air quality. If the air quality is good, we call the sheriff’s department before burning. This is so that if someone reports smoke or fire, they know not to send out firefighters.

A light breeze helps push the fire through standing dried-out prairie grass, but too much wind can be dangerous. Our permit allows us to burn only if the wind is 20 mph or less.

Consideration of Neighbors

Because busy 30th Street Drive is our south property border we burn only when a south wind will push smoke away from the road and neighbor’s homes. North of our property is a large woodland where no one lives and there’s plenty of space for the smoke to disperse.

Rewards After Burning

Burning takes planning and preparation but the actual burn is over in a flash. On November 5th we were all ready, called the sheriff, and lit the prairie just after 3 pm. Flames roared through the grass and stopped dead when they reached our mowed lawn. Less than an hour after striking the match our fire was completely out and we were munching on pizza.

Most homeowners can’t burn, but many can. It’s an interesting and natural way to manage property.  And, it’s fun.

Furless Tailed Squirrel Update

Update on Furless Tailed Squirrels

Furless tail on squirrel

Even in winter, the squirrels’ fur looks healthy…except for their tails.

Two winters ago, we noticed squirrels with nearly furless tails visiting our bird feeders. Our blog about them on Winding Pathways brought hundreds of visitors. Some from other countries! Apparently, we weren’t the only people seeing these hapless animals.

Last winter we had almost no squirrels in the yard. We wonder if the malady that caused them to lose tail fur might have knocked their population way back.

This fall we’re seeing plenty of both fox and gray squirrels in our yard. Their populations have rebounded. And, they have long, furry tails! Squirrels make us happy. While many people don’t like them gobbling seeds at the feeder, we are OK with that and find them as fascinating and fun as cardinals, chickadees, and goldfinches.

Squirrels and the Derecho

Now three years since the disastrous derecho that felled thousands of trees in the Eastern Iowa area, we’re seeing the vital work squirrels do. In the wake of the storm, people planted thousands of trees. Then came three drought years. The National Weather Service placed Cedar Rapids into its exceptional drought category in 2023.

The drought killed many human-planted trees but the ones planted by squirrels are doing just fine. Thanks to them, baby hickories, walnuts, and oaks are poking through the soil in nearby woodlands and our yard.

This fall we’ve watched squirrels carry acorns and walnuts across the yard, dig frantically, and bury their treasure. These enthusiastic gatherers and diggers plan to return during winter’s lean months to retrieve dinner from underground storage. Fortunately, squirrels bury more nuts than they’ll ever need. Unfortunately for them, some of the furry hoarders die with their hidden hoard untouched to sprout in the spring. Squirrels are master tree planters.

American Ninjas in the Yard

An oak and a walnut live about 150 feet south of our back deck.  Acorns and walnuts are epicurean squirrel delights, and our trees attract the furry acrobats. Squirrels like to use treetops as highways, jumping from one to the next. Our oak and walnut presented them with a problem. There is a several-foot gap between their branch tips. We are fascinated watching the squirrels make the long leap from twig to twig, sometimes leaping up to reach a branch on another tree, often while clutching a nut in its teeth. Their athleticism is astounding. So is their courage.

Squirrels fall. Twice we’ve seen one lose its grip and drop from the top of enormous trees. Both times the furry animals spread eagle their legs and tails while descending and hit the ground with a thump. They are shaken, rest, and then scamper off. A fall that would instantly kill a person, is hardly phased by the squirrels.

This winter we’ll again welcome squirrels to our feeders. They can dine on whole or cracked corn and cobs. We are assured of entertainment with their romps, athleticism and enthusiasm.

What is a Magnet Oak?

Magnet bur oak

Magnet bur oak in front yard

We didn’t intend to create a magnet when we planted a skinny bur oak in our front yard 13 years ago.

It created a startling experience one October evening when Marion went to the porch to check the weather. A large furry form dropped from the nearby tree and scurried away in the gathering darkness. A woodchuck? Not likely. They work the day shift. Later we caught the mystery animal in the bean of a flashlight as it returned to the magnet tree. A husky raccoon that again retreated in haste when it saw us.

Over the next several days we watched squirrels and woodchucks forage on the acorns. At dusk bucks and does with yearlings eagerly, yet watchfully, gobbled up acorns. In between, turkeys wandered by to forage. Blue jays dropped out of the tree onto the ground and carried off husky acorns to store for winter.

Why Oaks Attract Wildlife

Our October oak was a perfect magnet. While most area oaks were acorn-bare, our youthful front yard tree was loaded with them. They were huge, sweet, and free of the weevils that often consume acorns before exiting through tiny holes.

Blue jays, wild turkeys, woodchucks, raccoons, squirrels, and deer consider October acorns prime carbohydrate-loaded food. When few oaks, scattered around, bear a heavy crop, wild animals beeline to those loaded with nuts. That’s why our tree was a magnet drawing in a stream of wildlife until every acorn was consumed.

General Types of Oaks

White oak types have leaves with rounded lobes. These include white, bur, and swamp white oaks. Their big acorns are low in tannic acid and are a prized animal and human food. Most trees only bear a heavy crop every few years with acorns that sprout almost as soon as they hit the ground. If not eaten soon weevils find them.

Black oak types have leaves with pointed lobes. Their acorns are loaded with bitter tannin. Often wild animals only feast on them after nearby sweeter white oak-type acorns have all been eaten. Black oak-type acorns wait until next spring to sprout. Perhaps their tannic acid helps them remain uneaten until they sprout months after falling from the tree.

Optimal Places to Plant Oaks

When planted in an ideal location with full sun and rich soil, an oak will begin producing acorns when it’s seven to ten years old. Our front yard tree had a light crop the past few years, but when it reached its 13th year it was loaded with nuts. It was a true magnet that lured wildlife in from far and wide. We enjoyed watching many animals dine on acorns produced by a tree we planted.
