Why Are Birds Attacking My Windows?

Thwap. Thwap. Thwap. Nothing says “springtime” like the maddening, irregular percussion of a bird's beak rapping repeatedly against your window. But why would any animal do this to itself (or to you, for that matter)?

It's not personal. We promise.

Each year, as the warm weather rolls around, migratory birds like robins (Turdus migratorius) and cardinals (Cardinalis cardinalis) stake out their territories in our neighborhoods. These nesting sites will be where they find mates and make babies, which means that location and security are of vital importance. A good mate-to-be will guard its territory against any unfamiliar bird face—even when that face is its own.

To you—safe, if irritated, inside your home—your windows appear transparent. But to belligerent birds in bright daylight, you may as well have tiled the exterior with mirrors. A robin looking at your house sees another robin looking back at him. And then, of course, they fight. (Turkeys attack clean, shiny cars for the same reason. No bird attacks a dirty car. We’re just throwing that out there. We’re here to help.)

Window attacks are different from bird strikes, the violent collisions that occur when a bird thinks your house is the sky and flies straight into it. Strikes are dangerous and often deadly for the birds involved. Territorial attacks are mostly just annoying for everyone, including the bird.

If you do hear a bird strike or your avian assailant attacks too hard for its own good, you may want to go outside and check that it’s okay. If the bird looks all right—both wings in place, eyes focused, able to sit upright—just leave it alone. It should be fine. If you can see some kind of injury, the best thing to do is to get the bird to safety. Use a clean towel to lift it into a dark container, like a shoebox, and set it down somewhere safe and quiet. After 15 minutes or so, try opening the box outdoors; the bird might fly out on its own. If it still shows no signs of recovery, take it to your nearest wildlife rehabilitation center.

If you tend to find your home beset by angry birds, there are some concrete things you can do. For starters, move any feeders away from windows to discourage visitors. Then stand outside on a bright afternoon and check your windows for glare. You can cover any offending surfaces with fine mesh netting or a drop cloth to disrupt the reflection, or apply one-way film to make the glass appear opaque from the outside. If you’re really desperate and have some time (and extra cash) on your hands, you can install shutters on the outside of the house.

Unfortunately, covering one window may simply push your problem a few feet away. American robins in particular have been known to attack as many as 15 windows in a single house. “A territorial bird can be very persistent,” the Massachusetts Audubon Society notes on its site. “The best course of action is to be patient and wait for the breeding season to end [usually around August].”

Hang in there.

Presidents Day vs. President's Day vs. Presidents' Day: Which One Is It?

Happy Presidents’ Day! Or is it President’s Day? Or Presidents Day? What you call the national holiday depends on where you are, who you’re honoring, and how you think we’re celebrating.

Saying "President’s Day" implies that the day belongs to a singular president, such as George Washington or Abraham Lincoln, whose birthdays are the basis for the holiday. On the other hand, referring to it as "Presidents’ Day" means that the day belongs to all of the presidents—that it’s their day collectively. Finally, calling the day "Presidents Day"—plural with no apostrophe—would indicate that we’re honoring all POTUSes past and present (yes, even Andrew Johnson), but that no one president actually owns the day.

You would think that in the 140 years since "Washington’s Birthday" was declared a holiday in 1879, someone would have officially declared a way to spell the day. But in fact, even the White House itself hasn’t chosen a single variation for its style guide. They spelled it “President’s Day” here and “Presidents’ Day” here.

Maybe that indecision comes from the fact that Presidents Day isn’t even a federal holiday. The federal holiday is technically still called “Washington’s Birthday,” and states can choose to call it whatever they want. Some states, like Iowa, don’t officially acknowledge the day at all. And the location of the punctuation mark is a moot point when individual states choose to call it something else entirely, like “George Washington’s Birthday and Daisy Gatson Bates Day” in Arkansas, or “Birthdays of George Washington and Thomas Jefferson” in Alabama. (Alabama loves to split birthday celebrations, by the way; the third Monday in January celebrates both Martin Luther King Jr. and Robert E. Lee.)

You can look to official grammar sources to declare the right way, but even they don’t agree. The AP Stylebook prefers “Presidents Day,” while Chicago Style uses “Presidents’ Day.”

The bottom line: There’s no rhyme or reason to any of it. Go with what feels right. And even then, if you’re in one of those states that has chosen to spell it “President’s Day”—Washington, for example—and you use one of the grammar book stylings instead, you’re still technically wrong.

Full vs. Queen Mattress: What's the Difference?

If you’re in the market for a new mattress this Presidents Day weekend (the holiday is traditionally a big one for mattress retailers), one of the first decisions you’ll need to make is regarding size. Most people know a king mattress offers the most real estate, but the difference between a full-sized mattress and a queen-sized one provokes more curiosity. Is it strictly a matter of width, or are depth and length factors? Is there a recommended amount of space for each slumbering occupant?

Fortunately, mattress manufacturers have made things easier by adhering to a common set of dimensions, which are sized as follows:

Crib: 27 inches wide by 52 inches long

Twin: 38 inches wide by 75 inches long

Full: 53 inches wide by 75 inches long

Queen: 60 inches wide by 80 inches long

King: 76 inches wide by 80 inches long

Depth can vary across styles. And while you can find some outliers—there’s a twin XL, which adds 5 inches to the length of a standard twin, or a California king, which subtracts 4 inches from the width and adds it to the length—the four adult sizes listed above are typically the most common, with the queen being the most popular. It's 7 inches wider than a full (sometimes called a “double”) mattress and 5 inches longer.

In the 1940s, consumers didn’t have as many options. Most people bought either a twin or full mattress. But in the 1950s, a post-war economy boost and a growing average height for Americans contributed to an increasing demand for larger bedding.

Still, outsized beds were a novelty and took some time to fully catch on. Today, bigger is usually better. If your bed is intended for a co-sleeping arrangement with a partner, chances are you’ll be looking at a queen. A full mattress leaves each occupant only 26.5 inches of width, which is actually slightly narrower than a crib mattress intended for babies and toddlers. A queen offers 30 inches, which is more generous but still well below the space provided by a person sleeping alone in a twin or full. For maximum couple comfort, you might want to consider a king, which is essentially like two twin beds being pushed together.

Your preference could be limited by the size of your bedroom—you might not be able to fit a nightstand on each side of a wider bed, for example—and whether you’ll have an issue getting a larger mattress up stairs and/or around tricky corners. Your purchase will also come down to a laundry list of options like material and firmness, but knowing which size you want helps narrow down your choices.

One lingering mystery remains: Why do we tend to shop for mattresses on Presidents Day weekend? One reason could be time. The three-day weekend is one of the first extended breaks since the December holidays, giving people an opportunity to trial different mattress types and deliberate with a partner. Shopping Saturday and Sunday allows people to sleep on it before making a decision.
