What Should I Do If Animals or Birds Are in My Chimney?
Scratching, chirping or other unusual sounds from a chimney may indicate bird or animal activity, nesting material or debris. The safest next step is to avoid reaching into the chimney or attempting roof access and have the accessible chimney system evaluated.
Possible signs
Signs There May Be an Animal or Bird in Your Chimney
These signs may point to bird or animal activity, but sounds alone do not always confirm the cause. Debris, wind or other conditions can sometimes produce similar signs.
Chirping
Bird sounds that seem to come from inside the chimney or fireplace.
Scratching
Scratching or clawing noises along the flue or near the damper.
Fluttering
Wing-like fluttering sounds, sometimes at certain times of day.
Movement sounds
Shuffling or other movement heard from inside the chimney.
Nesting material
Twigs, grass or similar material falling into the firebox.
Feathers
Feathers appearing in the fireplace or on the hearth.
Unusual odors
New or unexpected smells coming from the fireplace area.
Debris or activity
Debris entering the fireplace, or visible activity near the chimney top.
Why it happens
Why Do Birds and Animals Enter Chimneys?
Several general factors can make a chimney accessible or attractive to birds and animals.
Open chimney tops
A chimney without a cover leaves an opening at the top.
Missing chimney cap
Without a cap, there may be little to limit entry into the flue.
Damaged cap
A cap with damaged or loose parts may leave gaps.
Shelter
A chimney can offer a sheltered space away from weather.
Nesting opportunities
Some birds and animals may use a chimney as a place to nest.
Accidental entry
Some animals may fall or wander in and have difficulty getting out.
Airflow
Can Nesting Material Affect the Chimney?
Nesting material, leaves or debris may obstruct part of the flue or affect airflow. Not every nest blocks a chimney completely, but restricted airflow can contribute to fireplace smoke and draft problems.
Odors
Can Animal Activity Cause Chimney Odors?
Nesting material, debris or animal activity may contribute to unusual smells from the fireplace area. Learn more about chimney and fireplace odors.
Safety first
Why You Should Not Reach Into the Chimney
An unknown obstruction or a live animal can make chimney access unsafe. For your safety, homeowners should not:
- Reach into an unknown obstruction.
- Climb onto the roof.
- Dismantle chimney components.
- Try to force an animal out.
- Light a fire to make an animal leave.
Finding the cause
Why a Chimney Inspection Can Help
A chimney inspection may help identify accessible conditions such as:
- • Nesting material
- • Debris
- • Visible obstruction
- • Chimney cap condition
- • Flue concerns
- • Other chimney conditions
Learn more about our chimney inspection service. An inspection does not include wildlife removal.
After the activity
When Chimney Cleaning May Be Appropriate
Once animal activity or debris concerns have been resolved appropriately, cleaning may be useful when accessible soot, nesting debris or other material remains in the chimney. Chimney cleaning is not animal removal. Learn more about chimney sweeping and cleaning.
Prevention
Can a Chimney Cap Help Prevent Future Entry?
A properly fitted chimney cap may help limit future entry by birds, animals, leaves and debris while allowing the chimney to vent appropriately. Learn more about chimney cap installation.

Common questions
Animals and Birds in Chimney FAQs
Why do birds get into chimneys?+
An open chimney top, a missing or damaged cap, or the shelter a chimney provides can make it a possible nesting or resting spot. Some birds may also enter by accident.
What does an animal in a chimney sound like?+
Homeowners often describe chirping, scratching, fluttering or movement sounds. Sounds alone do not always confirm the cause, so an inspection may be needed to identify what is present.
Can a bird nest block a chimney?+
Nesting material can obstruct part of the flue and may affect airflow. Not every nest causes a complete blockage, but it is worth having the chimney checked.
Should I light a fire to make an animal leave?+
No. Do not light a fire to force an animal or bird out. It can harm the animal and may create smoke or safety problems if the flue is obstructed.
Can a chimney cap help keep animals out?+
A properly fitted chimney cap may help limit future entry by birds, animals, leaves and debris while still allowing the chimney to vent.
Should the chimney be inspected after animal activity?+
It is a good idea. An inspection of accessible components can help identify remaining nesting material, debris or cap and flue concerns.
