* Birds:
* Chimney swifts: These birds are specialized for chimney nesting, often building nests of twigs and saliva. They can be a nuisance as they create messy nests and can be noisy.
* Other birds: Occasionally, other birds like starlings, sparrows, or even owls might try to build nests in chimneys, especially if they have a draft or open area.
* Squirrels: These agile animals can climb into chimneys and build nests of leaves and twigs. They can be very destructive, chewing on wood and damaging the chimney structure.
* Bats: Bats might use chimneys for roosting, especially in older chimneys with gaps or openings.
* Raccoons: Though not as common as birds or squirrels, raccoons might occasionally use chimneys for shelter or a place to raise their young.
Important Note: It's crucial to prevent animals from nesting in your chimney. They can be a fire hazard, damage the chimney structure, and spread diseases. If you suspect an animal is living in your chimney, it's best to call a professional wildlife removal service.
