Spring has officially arrived, and with the warmer temperatures and longer days come new babies for many different kinds of animals. Unfortunately, many birds and small mammals may view your chimney as the perfect place to build a nest and raise their young. While many animals and their nests can be safely and humanely removed if they get into your chimney, one cannot: the chimney swift.
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.
Removing chimney swifts
If birds take up residence in your chimney, your first reaction may be to have them removed as soon as possible. Unfortunately for many homeowners, chimney swifts and several other species of migratory bird are protected under the Federal Migratory Birth Treaty Act. This law makes it illegal for anyone to remove or destroy chimney swift nests, eggs, or hatchlings, with severe fines and penalties for anyone who violates the law.
Luckily for those dealing with an unexpected nest of chimney swifts, the birds have a relatively short nesting period. Chimney swifts can lay, hatch, and raise their young in about six weeks. Likewise, as they nest in the spring and summer when fireplaces are not typically in use, the presence of a chimney swift nest of often little more than a minor inconvenience.
Keeping chimney swifts out
Because chimney swifts cannot be removed once they have taken up residence in your chimney, the best thing homeowners can do to prevent them is to have their chimney regularly inspected. A chimney inspection can ensure that there are no areas for chimney swifts to enter through, such as a damaged chimney cap.
Likewise, because chimney swifts are migratory they tend to return to the same nesting ground each year. Because of this, if you have chimney swifts find their way into your chimney it is extremely important to have the chimney inspected and repaired after they leave. If not, you may find that your chimney becomes an annual summer home for a family of chimney swifts.
