Chimney Nests & the Uninvited Guests: A Closer Look at the Jackdaw

Jackdaws (Corvus monedula) are small, black-coloured birds that are part of the crow family. They have distinctive grey or silvery patches on the back of their heads and necks, which are known as “shawls”.

They have a short, sturdy bill, and are about 34cm in length, with a wingspan of around 70cm. They have built a reputation for being nuisance birds as they are well known for stealing other bird’s eggs and nestlings, breaking into garden feeders, and building nests in chimneys.

I think Jackdaws are Nesting in My Chimney; Should I Be Worried?

Discovering Jackdaws nesting in your chimney is a concern as this can cause a range of problems, including:

1. Blockage of chimneys: Jackdaw nests can block the chimney flue, preventing smoke and other combustion gases from escaping the home. This can lead to carbon monoxide poisoning, a potentially fatal condition.
2. Fire hazard: Jackdaw nests in chimneys can increase the risk of chimney fires. When debris from the nest comes into contact with hot flue gases, it can ignite and start a fire.
3. Structural damage: The weight of a Jackdaw nest can also cause damage to the chimney stack, leading to cracks or even collapse.
4. Noise pollution: Jackdaws are noisy birds, producing a repetitive, loud “kya” call.  Needless to say, their presence in a chimney will cause disturbance to homeowners.

What should I do if I Discover Jackdaws Nesting in My Chimney?

Attempting to remove a Jackdaw nest yourself can be dangerous, as it may involve working at heights or handling sharp tools.

It is also important to note that Jackdaws are protected under the Wildlife and Countryside Act (1981).  The Act makes it an illegal offense to intentionally kill, injure or take any wild bird, or to take, damage, or destroy their nests, eggs, or young.

Therefore, any removal of jackdaw nests should be carried out by a licensed professional who will have the necessary experience and equipment to do the job safely and effectively, with consideration for the welfare of the birds.

Call in the Professionals

Jackdaws are persistent birds that often return to the same nesting site year after year. When contacting a professional pest control agency to manage your Jackdaw situation, it is worth discussing preventative measures to help avoid the same situation next nesting season. Some options may include:

1. Chimney cowl or bird guard: Installing a cowl or bird guard on top of your chimney can help to prevent birds from entering. These devices are designed to allow smoke and gases to escape while preventing birds from entering the chimney.
2. Regular chimney cleaning: this can help to remove any nesting materials and prevent birds from returning to the same spot.
3. Close off the chimney: If you don’t use your fireplace or stove, consider closing off the chimney with a cap or other seal to prevent birds from entering.
4. Visual deterrents: Bird balloons, hawk kites or streamers can scare away Jackdaws. These can work well as long as you move them around every so often to avoid the birds getting used to them.
