How to Prevent Birds from Crashing Into Your Windows

Thump. We've all heard that sickening sound when a bird hits a window. It's so sad! Even if a bird flies away, it's usually injured and will die.

Birds don't "see" glass, especially if it's reflecting the surrounding landscape, which is usually does. Some birds, will "attack" their reflection in the window during breeding season. Cardinals are especially known for doing this.

If you think about how a bird flies through narrow branches in a tree, it's easier to understand how they just need to "see" a narrow opening to fly through. So a window is just a reflection of their world. As an example, look at this photo of a swallow flying through a narrow opening:

Bird-window collisions have a huge impact on bird populations. Scientists estimate that a bird hits a window every 9 seconds! That means an estimated 1 billion birds die annually from striking windows.

How can we prevent birds from crashing into our windows?

What we've tried that didn't work:

• Placing a hawk silhouette in the middle of the window. Birds got used to the predator silhouette and hit areas around the hanging silhouette.  Here's an image of a hawk silhouette:

• Sticky decals spaced far apart on a window. Birds hit the areas not covered by the decal. We didn't place the decals close enough.  Here's what FLAP, a bird advocacy group, recommends for placing decals effectively:

• Window screens that are part of the window. Birds still hit the screen and then the hard window right behind it.

What we've tried that did work, but isn't the best for our windows or us:

• Hanging reflective "scare" tape in long strips on the window frame. It works great! I used adhesive tape to attach the top of the strip to the window frame so the tape would move around in the breeze. But the tape left a sticky residue on the frame -- oops. And the flashing reflected back inside our house. The wind often blew the tape off the window frame. It was messy. But, it kept the birds from crashing into the window.

What we're trying this year:

• Scare tape attached to suction cup hooks. Scare tape worked well, but attaching it with adhesive tape wasn't a good idea. I'll try the suction cup hooks instead. Scare tape comes in different widths and can be purchased on Amazon. Suction cup hooks can also be purchased on Amazon.
• String wind curtain. This is just a row of thick string spaced every 6 inches and placed on the outside of the window. You can make your own or buy them at Bird Savers. I'll be using removable hooks attached to my window frames to hang the string curtain. You can buy suction cups with hooks also that attach right to the window.

• Feather guards: This is such a simple idea. Attach feathers to fish line and hang them on windows. Apparently, the feathers trigger a danger response in birds. It also breaks up the window opening and it adds movement to scare away the birds. But, like all deterents, they have to be spaced no further apart then 6 inches. You can purchase feather guards on Amazon, or make them yourself. Here's a video on how to make them - note that we'd place these 6-inches apart, not 16 inches:
  
  
  

Other methods from ornithology experts:

Scientists that study backyard birds have researched methods for preventing window collisions. Here's a list of what they recommend.

• Bird tape. The American Bird Conservancy recommends applying a special tape to your windows to break up the reflection. It can be purchased on ABC's Web site.
• Bird screen and netting. Screens or netting placed at least 2 inches from the window keeps birds from hitting the hard glass. Birds will still hit the screen, but apparently, most survive that unharmed. It's been 100% effective at preventing window collision deaths at the Cornell Lab of Ornithology. Here's a photo from their Web site showing the bird netting covering a window:

• Artistic window film. FLAP, a bird advocacy group, recommends this along with many other methods for preventing bird window collisions. Be sure to visit the FLAP Web site for more info. There's also a window film called "Collide Escape" that's available on Amazon.

• Soap. Yes, soap. Take a bar of soap and make squiggly lines 6-inches apart on the outside of your windows. It works, but looks pretty funny. Eventually, it will wash off. The American Bird Conservancy has a flyer with information on how to apply the soap.

Tough Winter? No Problem! Hardy Roses for Your Garden!

What a tough winter we've had this year! It's one for the record books for cold and snow.

Are you worried about your plants and how they've survived this cold winter?

We're not worried about our roses! For the past 25 years, we've grown lots of roses in our gardens in Wisconsin and know which ones will survive our tough winters year after year.

We grow three different "classes" or types of hardy roses: Climbing, Rugosa and Shrub. Here's a quick list of our favorites from each class.

Climbing Roses

The hardiest of all Climbing roses is William Baffin. Its canes survive -50 degrees (Zone 2)! It has vigorous growth with canes up to 10-feet tall or more. You can attach it to a trellis, post or arbor for a spectacular show of blossoms. It has rigid canes, so it's also great for hedges. We sell a lot of these for hedges and our customers love it.

William Baffin - deep pink, semi-double blossoms; grow up to 10-feet tall with long, rigid canes. It blooms profusely in mid June to early/mid July, with clusters of up to 30 blossoms.

We also offer other winter-hardy climbing roses, including John Cabot, John Davis and Henry Kelsey. They were developed in Canada and are named after Canadian explorers. They are beautiful in bloom and easy to grow. Try one for your garden!

Rugosa Roses

Rugosa roses are the most winter hardy of all the roses we grow. Most are hardy to Zone 3 or colder. They're also beautiful, fragrant and bloom all summer! They come in a wide range of colors from white to mauve. The blossoms can be single (5-petaled) or double (multi-petaled).

Most Rugosa roses also produce fruit called "rose hips" after they bloom. The blossoms are great for pollinating insects and you'll see lots of bumblebees on the blossoms. They're easily pruned to shape and also are great for hedges!

Here are three of our favorites that show the variety of blossom color, form and plant size in the Rugosa roses.

Belle Poitevine - pink, fragrant, double blossoms; grows up to 4-feet tall with a mounded shape. A beautiful rose with large, semi-double, medium-pink blossoms. The blooms are extremely fragrant and produced in flushes from early summer until frost.

Charles Albanel - mauve (pink/red), fragrant, double blossoms; grows up to 2-feet tall with a mounded shape. A wonderful rose in the garden and never disappoints us! Its fragrant blossoms have a mauve-red color and appear in abundance and June and then repeat until frost.

Fru Dagmar Hastrup - light pink, fragrant, single blossoms; grows up to 4-feet tall with a mounded shape. A lovely rose that's always a great addition to any garden. Blossoms are a light-pink color with delicate-looking petals that have a wonderful rose fragrance. It blooms all summer, with large, colorful rose hips following the blossoms.

Shrub Roses

Shrub roses are a very diverse group with colors from white to reds. Not all Shrub roses are winter hardy, though, so be careful to choose one that is hardy to your area (see the hardiness Zone map). We've grown alot of Shrub roses over the years. Here are two of our time-proven favorites for winter hardiness, healthy foliage and easy growth:

Morden Blush - light pink, double blossoms; grow up to 2-feet tall. This rose has beautiful, light-pink buds that have a delicate hybrid-team form. It blooms continuously with large clusters of double, cream to light-pink, slightly fragrant blossoms that appear all summer and into fall.

Sunrise Sunset - pink-yellow, semi-double blossoms; grows 2-3 feet tall. A lovely rose that's always in bloom from June to frost. Its blossoms are just beautiful -- the color is a blend of pinks with apricot yellow in the center.
