You might not be the only one who thinks your fireplace is cozy. If you’ve noticed noises or bad smells from your chimney, it’s possible that you’re unknowingly providing a nesting spot for a family of chimney swifts.

What are they, and what can be done about them?

The solution will involve a bit of waiting – legally, the birds need to migrate out on their own. But thankfully, once the chimney swifts have left, we can restore your chimney to its proper function – and make improvements to prevent their future return.

Identifying Chimney Swifts

Chimney swifts are small, migratory birds that divide their time between North and South America. They’re recognizable by their distinctive silhouette – chimney swifts have a cigar shaped body with long, sloping wings, and a short, bristly tail.

It’s actually unlikely that you’ll ever see them holding still – they spend most of their lives and perform nearly all the business of life in flight. When they do hold still, chimney swifts can’t perch. Instead, they roost by clinging to rough, vertical surfaces such as hollow trees, cave walls, and – you guessed it – chimneys. They’ll also nest in these places, building nests on their roosting surfaces by bonding twigs and other nesting material with their concrete-like saliva.

Can I Remove Swifts From My Chimney?

You may be wondering if you can rehome or chase away chimney swifts. In a word – no. This bird species is federally protected under the Migratory Bird Treaty Act. This means that it’s a matter of federal concern that chimney swifts be able to stay put in their home of choice during the nesting season.

So, here’s the big question…

When Will Chimney Swifts Leave My Chimney?

If you’ve become host to a family of chimney swifts, never fear. They aren’t creating a permanent residence. They arrive at their North American destinations in spring. After mating and nesting, a chimney swift will lay eggs – typically one to five – which will be incubated from 15-20 days. About a month after hatching, baby chimney swifts are ready to hunt and fly on their own, and they’re typically heading south for the winter in October.

If loud, high-pitched noise is what tipped you off to the presence of chimney swifts, know that the noisiest chimney swifts are babies, impatiently waiting to be fed during the last couple of weeks before leaving the nest. This means that if you’ve already noticed the racket, your swifts should be gone before too long.

While the birds, nests, and eggs cannot be removed, you can reduce the chance of exacerbating the issues they could cause. If you have a throat damper, be sure it is closed during the duration of their stay. This will keep the chimney swifts in the chimney and out of your living room!

An annual chimney inspection will help ensure that your damper is in good working order and able to keep these birds from entering your home.

They’re Gone – Now What?

Once the chimney swifts have left, act right away to get your chimney ready for its intended use before winter sets in.

A chimney cap helps keep things out – not only birds and animals, but also leaves, twigs, and water. Being proactive and capping your chimney will save you the sounds, smells, and headaches of having chimney swifts make a return visit. Your chimney cap will also be part of your defense against expensive water damage to your chimney, and it will prevent build up of other kinds as well.
