To Remove or Not to Remove
Spying an old bird’s nest tucked among the branches can stir curiosity. Should you reach up and remove the abandoned nest? Or is it better to leave the vacant nest where it is? If you’re short on time, here’s a quick answer: It’s generally best not to remove old nests from trees since they rarely pose any harm and may be reused by other birds or wildlife.
In this article, we’ll explore whether taking down an old nest is advised. We’ll look at how birds reuse nests, pros and cons of removal, and when discarding a nest makes sense for your unique situation.
Birds can abandon nests if disturbed or harassed, dooming eggs and hatchlings. Less obvious, repeated human visits close to a nest or nesting area can leave a path or scent trail for predators to follow.
You should clean your birdhouses out a minimum of once a year. Generally speaking, the hole in a bird box should be approximately 1.5 inches in diameter, but this may vary depending on the species of bird you are hoping to attract. Bird houses should be thoroughly cleaned after the nesting season ends and the last young birds have left the nest. Depending on the types of birds that have used the house, it may be ready for cleaning as early as late summer.
By understanding the laws and how to properly remove a home, it is possible to encourage safe building responsibly.
Legal Considerations and Cleaning Guidelines
Most nests are protected under the Migratory Bird Treaty Act (MBTA). It’s illegal to keep any nest without a U.S. Fish and Wildlife Service permit.
A clean box is most attractive to birds. At least clean out somewhat if keeping part of the old nest. Possible but not common, some birds raid and eat eggs.
Clean bird houses after the season when young birds left the nest. Mid to late fall, be sure all are cleaned. Remove old nests with gloves and goggles. Give a proper clean with dish soap and vinegar disinfectant. Clean once a year minimum before nesting season. Wait until after season. Signs to look for: birds flying to and from repeatedly.
Leaving old nests can cause parasites and bacteria, harmful to birds and young. Important to make sure the nest is inactive before removing. Highly protected species – destroying or moving active nests brings penalties.
Birds choose houses to nest on because they’re protected from weather and predators. Before removing nests, understand local wildlife laws and if it’s safe and comfortable for the birds.
When Is It Appropriate to Remove Bird Nests?
Nests should be removed when the location poses a risk to the birds or their babies. Remove or relocate bird nests found in doorways, active chimneys, and yard equipment.
Some nests should never be removed unless the proper wildlife authorities are consulted. These nests include:
- Endangered birds that are unlikely to build a new nest if disturbed.
- Nests of large birds that will be reused for many years.
- Raptor nests where defending adults can be aggressive.
- Natural cavities that would be destroyed to remove the nest.
- Any nest in early summer that may be reused for additional broods.
- Nests that would be unsafe for humans to reach and remove.
Best practice is to check with a wildlife company before attempting nest removal. Prevent building by removing food scraps and open trash. Make sure trash is secured. Place feeders and birdbaths away from the home. Consider installing gutter guards.
Remove nests before the birds lay eggs. Then make the area inaccessible and unattractive. It is illegal to remove or destroy active native bird nests in the U.S.
Care must be taken when removing nests so they are properly removed.
