Do Chimney Swifts Belong In My Chimney?

So, you have chimney swifts in your chimney. The next questions may be, do they belong there and is it a big deal if they stick around? Chimney swifts may think your chimney is the perfect spot to set up camp, but the truth is that using a chimney that has chimney swifts and their nesting materials inside of it is unsafe for both you and the creatures themselves.

At Lords Chimney, we come across this issue from time to time, and we feel that it’s an important subject for our customers to understand. Learn more about these animals below, then keep reading to discover the best ways to keep them out of your chimney for good. Our expert team is ready to help you out!

What Is A Chimney Swift?

A chimney swift is a small bird that is known for its ability to stay in flight for extremely long periods of time. They’re typically darker in color with rounded heads, long and curved wings, and short beaks, tails, and necks. They eat all types of airborne insects and, as far as nesting and building homes, they favor steep, sheltered areas like hollow trees, caves, garages, air vents, and – you guessed it – chimneys.

Another thing to note about chimney swifts is that their population is in decline, which is why they are protected by the Migratory Bird Treaty Act. This means, once they settle in your chimney to raise young, there’s not a lot you can do about it. In fact, purposefully hurting these birds or removing a nest that may contain eggs or young could land you with some fines and/or penalties!

So, what can be done once a family of chimney swifts moves in? The truth is – nothing. All that is left to do at this point is wait until they migrate back down south, so you can remove their nesting materials and make your fireplace safer for regular use again. Unfortunately, it’s not uncommon for the birds to come back to the same spot again year after year, so it’s important to take action now to ensure they can’t get into your chimney next spring.

Taking Preventative Action

One thing that can be done to keep chimney swifts, as well as other woodland critters, out of your chimney for good is to have a chimney cap installed. Chimney caps cover your flue opening, so that animals cannot enter your chimney to build nests and raise young. This benefits both you and the animals! Your home will be a lot safer and more comfortable, and the animals won’t get stuck with no way out again.

The great thing about chimney caps is that they provide plenty of other benefits, as well. They ensure excess moisture stays out of your chimney and help prevent downdrafts, so you’re not stuck with a smokey living space night after night. They’ll also stop sparks from escaping the chimney, so they don’t risk landing on your flammable roofing materials. Achieving peace of mind has never been easier!

What are chimney swifts?

Chimney swifts are very small grey and brown birds with cigar shaped bodies and wide, short bills. Chimney swifts are easily identified by their distinctive chirp as well as their sharp, jerky movements when flying. While chimney swifts spend their non-breeding winters in South America, they migrate back to North America for the spring nesting season each year. According to the Cornell Lab of Ornithology , “Their ability to travel over long distances and through a variety of habitats exposes them to a wide range of microorganisms.”

Why chimney swifts love to nest in chimneys

In year’s past, chimney swifts preferred to nest in hollow or dead trees. However, as cities have grown larger and wooded areas are harder to find, chimney swifts have been forced to adapt. In fact, chimney swifts got their name because they often seek out chimneys as their nesting sites.

Chimney swifts most commonly find their way into uncapped chimneys or chimneys with damaged chimney caps. Because they are so small, even the smallest hole in the netting or mesh of a chimney cap can be big enough for a tiny swift to fit through. Because they are a migratory bird that will return year after year to the same nesting site, it is important to have your chimney repaired as soon as the swifts have left to avoid their return.

About chimney swifts

A chimney swift can be recognized by their size, color, movements, and sounds. Chimney swifts are small birds with narrow bodies and long wings. While up close they are a brown-gray color, they may appear black when backlit against the sky. Swifts fly and twist side to side erratically, and have a distinct high pitched chirp.

Although chimney swifts spend their winters in South America, they migrate north to the eastern United States and Canada each spring to nest and raise their young. According to the Cornell Lab of Ornithology, “Their ability to travel over long distances and through a variety of habitats exposes them to a wide range of microorganisms.”

Chimney swifts got their name because of their unique ability to build nests that stick to the side of slippery flue tiles. While swifts traditionally prefer to nest in hollow or dead trees, the increase in size of cities, suburbs, and agricultural areas has forced them to adapt.
