While backyard birders may enjoy playing host to nesting birds and watching parents raise their young, birds do not always build their nests in safe or suitable locations. Before removing bird nests, however, it is important to understand local laws involving wildlife removal as well as whether or not removing the nest is safe for the birds.

Nest Removal Laws

Before removing any bird nest, determine whether or not the removal would be legal according to local wildlife laws.

Most birds are protected species and tampering with a nest could lead to hefty fines or other penalties. In the United States, for example, it is illegal to remove or destroy any active nest from a native bird species, defined as a nest with eggs or brooding adults in it. If the nest has been abandoned or no eggs have yet been laid, it can be removed or destroyed as needed. Nests of invasive birds, such as house sparrows or European starlings, however, are not protected. Laws in other countries may vary, and before interfering with any nest, it is best to determine the bird species and learn how local laws could impact your actions.

Why Remove Nests?

In certain circumstances it may be necessary and desirable to remove bird nests, both for safety and convenience. Proper reasons to remove nests include…

• The nest has been abandoned after the breeding season has ended.
• The nest is unused and has become dilapidated and unsafe for future use.
• The nest is in a bird house that needs to be cleaned out for future residents.

• The nest is in a dangerous location and brooding birds could become stressed.

In most cases, it is only after the nesting season has ended and the birds have moved on that nests can and should be removed. If the birds have built their nests in poor locations, however, the nest may need to be removed earlier to safeguard both the adults and the chicks they hope to raise. Unsafe locations typically include…

• Near a door or active walkway
• In gutter or drainage pipe
• Inside dryer vents
• On equipment, such as a grill or lawn mower
• Inside a chimney

If birds have built their nests in these types of locations, it is best to remove the nest and discourage the birds from rebuilding in the same spot. If the dangerous nest already has chicks or eggs, contact a bird rescue organization to see if they can take in the birds until they are mature enough to leave the nest, or else move the nest as little as possible to put it in a safer location nearby. The parent birds will return to the nearby nest to continue raising their young, and after the fledglings have left, steps can be taken to be sure the adults do not reuse the unsafe location.

Nests You Shouldn’t Remove

Some nests will not need to be removed or should not be removed regardless of the circumstances unless the proper wildlife authorities are consulted or there are no other options to keep the nesting birds safe. These nests include…

• Endangered birds that are unlikely to build a new nest if disturbed.
• Raptors or other large birds that will reuse the same nest for many years.
• Natural cavities that would be destroyed in order to remove the nest.
• Any nest in early summer that may be reused for additional broods.

When in doubt, it is always best to contact wildlife officials about nest removal, or to wait until long after the birds have left the nest before taking any action.

How to Remove a Bird Nest

When it is safe and appropriate to remove a bird’s nest, care must be taken so the nest is properly removed.

1. Double-check the nest for any remaining eggs or chicks, and wait to be sure the healthy birds have all left the nest before beginning any removal.
2. Wear gloves when handling the nest to protect against contamination from mites, bacteria or other parasites that may have infected the nest.
3. If possible, add the discarded nest to a compost pile or else dispose of it in a plastic bag so predators are not attracted to the nesting area where young birds may still be vulnerable.
4. Clean the area where the nest was located if necessary, using a solution of one part chlorine bleach to nine parts water. Note: It is not necessary to clean a tree or bush where a nest was located.

If you do not want birds reusing the same area after you have removed a nest, it will be necessary to take steps to deter birds from rebuilding. Changing the shape of the surface where the birds constructed their nest – by adding a board or spikes to make it less welcoming – will help discourage nesting, as will putting a cat or owl decoy near the nesting area to give the illusion of danger. Vigilance at the beginning of the nesting season will also be necessary, and removing nests before they are completed will help encourage unwise birds to move to a different area.

Watching nesting birds is always a treat, but there are times when a nest is not placed appropriately either for the birds or the birders. By understanding the laws behind nest removal and how to properly remove a nest, it is possible to encourage safer nesting in a responsible way.
