Birds in the Dryer Vent: How They Get In and How to Keep Them Out
Every spring we get the same calls: scratching and chirping from the laundry room wall, a dryer that suddenly takes forever, and — the giveaway — twigs sticking out of the vent hood outside. A bird, usually a starling or a sparrow, has moved into the vent.
Why vents make perfect nests
From a bird's perspective, an unguarded vent hood is a pre-built nesting cavity: elevated, sheltered from rain and predators, and warmed every time you run a load. If the damper is stuck, broken or missing — common on older covers — there's nothing between a determined bird and a four-inch tunnel straight to your dryer.
What a nest does to the vent
Nests aren't tidy. Birds pack the opening and the first feet of duct with twigs, grass and feathers, and the lint your dryer exhausts glues it all together. Airflow chokes off, drying times jump, the dryer runs hot — and the nest itself is dry, flammable material sitting at the end of a hot exhaust line. It's a blockage and a hazard in one package.
Getting them out — humanely and completely
Removal means more than pulling the visible twigs. Nest material travels deeper than it looks, and eggs or young birds change the job — they'll be handled carefully and, where the law protects them, worked around until they've fledged. Once the line is clear, it gets a full cleaning, because nest debris and lint are mixed through the run.
Keeping them out: guards, not screens
The instinct to staple mesh over the vent is understandable — and wrong. Fine screens clog with lint quickly, choke the dryer, and create a new fire risk; they're specifically warned against for dryer vents. The correct fix is a dryer-vent-rated bird guard: wide openings that block birds and rodents while letting air and lint pass freely, paired with a cover whose damper swings properly. We test the swing with the dryer running before we leave — protection that costs airflow is no protection at all.
