Is It Illegal to Move a Bird’s Nest? Laws and Facts 2026

Moving a bird’s nest is illegal under federal law when the nest belongs to a protected migratory bird species and the nest is active, meaning it contains eggs, chicks, or is currently in use. The Migratory Bird Treaty Act of 1918 makes this a federal crime with real penalties.

Most people have no idea that something as simple as relocating a nest can carry federal misdemeanor charges. The penalty can reach $15,000 per violation and up to six months in jail for a first offense.

This article explains exactly which nests are protected, which are not, how active versus empty nests are treated differently, what exceptions exist, and what legal alternatives you have when a nest is in a genuinely problematic location.

Is It Illegal to Move a Bird’s Nest?

Moving a bird’s nest is illegal under federal law when the nest belongs to a protected migratory bird species and contains eggs, chicks, or is actively in use. The Migratory Bird Treaty Act (MBTA), codified at 16 USC 703, prohibits the taking, possession, purchase, barter, sale, or destruction of migratory birds and their nests and eggs without a valid federal permit.

The law applies to nearly all native North American bird species. Over 1,000 species fall under MBTA protection. That covers the majority of the birds that people commonly encounter in their backyards, on their rooftops, and around their properties.

The practical implication is clear. Before you move, destroy, or interfere with any bird’s nest on your property, you need to know whether it is protected and whether it is currently active.

Quick Facts:

• The MBTA covers over 1,000 native North American bird species
• Active nests with eggs or chicks are fully protected under federal law
• Empty nests from a completed breeding season can generally be removed
• Three specific non-native invasive species are explicitly excluded from MBTA protection
• Penalties include fines up to $15,000 and up to six months imprisonment for individuals

Is It Illegal to Remove a Bird’s Nest?

Removing a bird’s nest is illegal when the nest is active and belongs to a protected species under the Migratory Bird Treaty Act. An active nest is one that contains eggs, live young, or is currently being built and used by a nesting pair.

The prohibition applies regardless of where the nest is located. It does not matter whether the nest is on your own private property, on a structure you own, or even inside your vehicle. Federal law protects the nest based on the species and the nest’s active status, not based on property ownership.

Empty nests that have been abandoned after the breeding season is complete occupy a different category. The MBTA protects birds, eggs, and nests in use. Once a nest is fully vacated and the breeding cycle is complete, it is generally legal to remove the physical structure, though some species-specific rules may still apply.

Nest removal legality by status:

Is It Illegal to Disturb a Bird’s Nest?

Disturbing a bird’s nest is illegal under the MBTA when the disturbance interferes with an active nest of a protected species. “Disturb” under the law is interpreted broadly and includes actions that cause the parents to abandon the nest, damage the nest structure, or interfere with breeding success.

The federal prohibition is not limited to physically moving the nest. Actions that destroy the nest, frighten the nesting birds into abandoning eggs or chicks, or damage the tree or structure supporting the nest can all constitute a violation. Courts have applied the MBTA to a wide range of conduct that results in harm to protected birds and their nests.

For homeowners and property managers, this means that even trimming a tree or hedge near an active nest could create legal exposure if the disturbance causes nest abandonment. Practical caution requires checking for active nests before any vegetation trimming or construction work during nesting season.

Types of disturbance covered by the MBTA:

• Physically moving or relocating the nest
• Destroying the nest structure directly
• Cutting or trimming vegetation that supports the nest during active use
• Frightening nesting parents through noise, presence, or activity to the point of abandonment
• Spraying pesticides near or on an active nest
• Removing eggs from the nest
• Any action that results in nest failure for a protected species

Key Takeaway: The MBTA’s protection for bird nests extends beyond physical removal. Any action that causes nest failure for a protected species during the breeding season can constitute a federal violation, including vegetation trimming and construction near active nests.

Migratory Bird Treaty Act and Bird Nests

The Migratory Bird Treaty Act is the primary federal law governing the protection of migratory bird nests in the United States. Enacted in 1918 and codified at 16 USC 703 through 712, the MBTA implements four international treaties between the US and Canada, Mexico, Japan, and Russia for the protection of migratory bird species.

The law makes it illegal to pursue, hunt, take, capture, kill, possess, sell, purchase, barter, import, export, or transport any migratory bird, or any part, nest, or egg of any such bird, except under the terms of a valid permit issued by the US Fish and Wildlife Service (USFWS).

The word “take” in the statute has been interpreted broadly by federal courts and USFWS to include any action that results in harm to a migratory bird or its nest. The MBTA applies to intentional acts and in some enforcement contexts has been applied to negligent or incidental take as well.

MBTA key provisions:

Which Bird Nests Are Protected by Law?

The nests of all native migratory bird species listed under the MBTA are protected by federal law. This includes over 1,000 species that are native to North America or that migrate through the United States.

The scope of coverage is much broader than most people realize. The common American robin is protected. So are house finches, mourning doves, swallows, wrens, warblers, sparrows, and hundreds of other species that regularly nest around homes and property.

Eagles receive additional protection under the Bald and Golden Eagle Protection Act, which carries even heavier penalties. Birds listed under the Endangered Species Act carry their own separate federal protections with the most serious penalties.

Commonly encountered protected species and their nests:

Can You Move an Active Bird’s Nest?

Moving an active bird’s nest, meaning one that contains eggs or live young, is illegal without a federal depredation permit from the US Fish and Wildlife Service. There are no general exceptions for homeowners or property owners when the nest belongs to a protected species.

An active nest is under the full protection of the Migratory Bird Treaty Act the moment eggs are laid. Some wildlife officials extend that protection to nests under active construction before eggs are laid, based on the argument that the birds and their breeding activity are already protected and nest disturbance can cause abandonment.

The practical reality is that moving an active nest typically results in abandonment. Parent birds that return to find their nest relocated to a different location frequently abandon the eggs or chicks. This outcome, nest failure due to human interference, is precisely what the MBTA is designed to prevent.

What “active” means for legal purposes:

• Eggs present in the nest: Fully active; removal is a clear MBTA violation
• Live hatchlings or nestlings present: Fully active; removal is a clear MBTA violation
• Nest under construction with no eggs yet: Gray area; technically a violation risk
• Adults present and using the nest regularly: Active; disturbance that causes abandonment is a violation risk
• No birds seen for several weeks during nesting season: Possibly abandoned; proceed with caution

Can You Move an Empty Bird’s Nest?

Moving an empty bird’s nest is generally legal once the breeding season is complete and the nest has been fully vacated. The MBTA protects birds and their active nesting activities; it does not extend indefinitely to vacant nest structures after the birds have finished breeding.

The timing of an empty nest matters. A nest that appears empty in late summer after the breeding season has ended is different from a nest that appears empty in early spring when birds may not yet be present but the nesting season is beginning. Removing an apparently empty nest in early nesting season risks disturbing a nest just before or after eggs are laid.

For nests on structures like your home, gutters, or outbuildings, waiting until late fall or winter to remove empty nests is the safest legal approach. By that point, breeding is complete, the birds have moved on, and no violation of the MBTA can reasonably occur.

Safest times to remove empty nests:

• Late fall (October to November) after breeding season concludes
• Winter months when most migratory birds have departed
• Before nesting season begins in early spring (but this varies by species and region)
• Never during nesting season when active use is possible even without visible eggs

Key Takeaway: Empty bird nests from completed breeding seasons can generally be removed without legal violation. Active nests with eggs or chicks cannot be moved without a federal permit, period.

Is It Illegal to Move a Bird’s Nest With Eggs?

Moving a bird’s nest with eggs in it is illegal under the Migratory Bird Treaty Act when the eggs belong to a protected species. This is one of the clearest and most unambiguous violations of the MBTA for ordinary homeowners and property owners.

Eggs in a nest are explicitly protected by 16 USC 703. The statute specifically covers nests and eggs of protected species. Taking, moving, possessing, or destroying those eggs without a valid federal permit constitutes a federal violation with criminal penalties.

The eggs do not have to hatch for the violation to occur. The moment you physically move a nest containing eggs of a protected species without authorization, the violation is complete. It does not matter whether the eggs were viable, whether the parents were present, or whether the nest was in an inconvenient location on your property.

Nest with eggs: legal analysis:

• Protected species eggs in nest: Federal crime to move without USFWS permit
• Non-protected species eggs (house sparrow, starling, pigeon): Legal to remove
• Unknown species: Treat as protected until confirmed otherwise
• Eggs already fallen from nest: Complicated; do not disturb further without guidance from USFWS
• Eggs in a structure causing immediate safety risk: Contact USFWS for emergency guidance

Bird’s Nest on Your House: Is It Legal to Remove?

A bird’s nest on your house is not automatically legal to remove simply because it is on your private property. The location of the nest on property you own does not change the MBTA’s application. The law protects the nest based on the species and active status, not the property’s ownership.

This surprises many homeowners. The instinct is that your property, your rules. But federal wildlife law overrides that instinct when protected species are involved. Removing an active protected nest from your eaves, gutters, porch, or roofline is a federal violation regardless of the inconvenience it causes.

The practical approach for homeowners dealing with nests on structures is to wait until the nesting season concludes, the chicks fledge and leave, and the nest is fully abandoned before removing it. That timeline is typically four to eight weeks from egg laying to fledging for most common songbird species. After the nest is empty and the season is complete, removal is legal.

Homeowner timeline for legal nest removal from structures:

• Discovery of nest: Confirm whether active (eggs or chicks present)
• If active: Wait; do not disturb; estimate 4 to 8 weeks for most songbirds
• Once chicks fledge and parents stop returning: Nest is abandoned
• After breeding season ends (late summer to fall): Remove the empty nest structure
• For prevention: Seal potential nesting sites before nesting season begins

Is It Illegal to Remove a Robin’s Nest?

Removing an American robin’s nest is illegal under the Migratory Bird Treaty Act when the nest is active. The American robin (Turdus migratorius) is specifically listed as a protected migratory species under the MBTA and has been since the act’s original passage in 1918.

Robins are among the most common birds that nest on structures like porches, window ledges, and light fixtures. Their tendency to nest close to human habitation makes them a frequent subject of this question. But their abundance and familiarity do not diminish their federal protected status.

An active robin’s nest with the characteristic blue eggs or with hatchlings cannot be legally removed without a federal depredation permit. The robin’s nesting period from egg laying to fledging is typically about five weeks total. Waiting out that period is the legally required approach when an active nest is discovered.

Robin nesting timeline:

• Nest construction: 2 to 6 days
• Eggs laid: 3 to 5 pale blue eggs, one per day
• Incubation period: Approximately 14 days
• Nestling period: Approximately 13 days before fledging
• Total time from first egg to fledging: Roughly 27 to 29 days
• Legal removal window: After all chicks have fledged and parents have stopped returning

Is It Legal to Move a Hummingbird Nest?

Moving a hummingbird nest is illegal under the Migratory Bird Treaty Act when the nest is active. All North American hummingbird species, including the ruby-throated hummingbird, Anna’s hummingbird, and other native species, are fully protected under the MBTA.

Hummingbird nests are notably small and often difficult to spot, built of plant fibers and spider silk and camouflaged with lichen on tree branches. Despite their size, the nests carry full federal protection.

Moving a hummingbird nest with eggs or chicks is a federal violation. The birds typically lay two eggs per clutch and incubate them for approximately 14 to 23 days depending on the species. Fledging takes another 18 to 30 days. Any interference with the nest during that period is illegal without a USFWS permit.

Key Takeaway: All native North American hummingbird species are fully protected under the MBTA. Moving an active hummingbird nest, however small or easy to overlook, is a federal violation subject to the same penalties as disturbing any other protected migratory bird nest.

Unprotected Bird Nests: Which Are Legal to Remove?

Three specific species are explicitly excluded from MBTA protection, making their nests legal to remove at any time: the house sparrow, the European starling, and the rock pigeon. All three are non-native invasive species introduced to North America from Europe, and Congress specifically excluded them from MBTA coverage.

This exclusion is significant for homeowners dealing with pest bird problems. House sparrows aggressively compete with native birds for nesting sites. European starlings form large flocks that damage crops and structures. Rock pigeons create health hazards and property damage through their droppings. Their nests, eggs, and chicks can all be legally removed without a federal permit.

State laws add another layer. While the MBTA does not protect these three species, some states have their own wildlife statutes that may impose additional requirements. Checking your state’s specific wildlife regulations is advisable before taking action.

Non-MBTA protected species and their status:

Depredation Permit for Bird Nest Removal

A depredation permit from the US Fish and Wildlife Service is the legal authorization that allows removal or relocation of active protected bird nests in specific circumstances. Without this permit, there is no general exception for homeowners or property managers dealing with active protected nests.

USFWS issues depredation permits when the nesting activity creates a legitimate documented conflict with human health, safety, or economic activity. Examples include nests in active electrical equipment, nests creating contamination risks in food processing facilities, or nests in aircraft hangars where bird activity creates aviation safety risks.

The permit application process requires demonstrating the specific conflict, describing the proposed management action, and justifying why less disruptive alternatives are not available. Permits are not routinely issued for situations of mere inconvenience. A robin nesting on your porch light is inconvenient; it does not typically qualify for a depredation permit.

Depredation permit application process:

• Identify the specific conflict requiring permit authorization
• Contact the regional USFWS Migratory Bird Permit Office
• Submit a depredation permit application with documentation of the conflict
• Describe why less disruptive methods cannot resolve the problem
• Await review and issuance of the permit before taking any action
• Comply with all conditions specified in the issued permit
• Report results as required by the permit conditions

Penalty for Disturbing a Bird’s Nest

The penalty for disturbing a protected bird’s nest under the Migratory Bird Treaty Act includes criminal fines and potential imprisonment. The MBTA establishes two tiers of criminal liability: misdemeanor violations for standard offenses and felony violations for commercial or knowing violations.

Under 16 USC 707(a), a misdemeanor conviction for violating the MBTA carries a maximum fine of $15,000 and imprisonment of up to six months. This is the tier most likely to apply to individual homeowners or property owners who remove or disturb an active protected nest without authorization.

Under 16 USC 707(b), felony violations committed by knowing actors or in the context of commercial activity carry fines up to $250,000 for individuals and up to two years in federal prison. These provisions target commercial operators, developers, and others who knowingly disturb nests at scale as part of economic activity.

MBTA penalty structure:

In practice, USFWS and the Department of Justice typically pursue MBTA enforcement against large-scale violators such as energy companies, developers, and others with significant economic activity. Individual homeowners who accidentally disturb a nest are more likely to receive a warning. But the criminal penalty authority exists and has been used.

State Laws on Bird Nest Removal

State laws on bird nest removal add another regulatory layer on top of federal MBTA protections. Most states have their own wildlife protection statutes, and some provide additional protections for state-listed endangered or threatened species that may include birds not covered by the MBTA.

California has some of the most stringent state-level bird protections in the country. The California Department of Fish and Wildlife enforces nest disturbance prohibitions under California Fish and Game Code 3503.5 and 3503, which broadly prohibit taking, possessing, or destroying nests or eggs of birds. California also has a specific prohibition on disturbing active nests during grading and construction under its environmental review process.

New York, Washington, Oregon, and several other states have parallel state-level migratory bird protections that can be enforced independently of federal law. Violators can face both federal MBTA charges and state wildlife charges for the same conduct.

When Can You Legally Remove a Bird’s Nest?

You can legally remove a bird’s nest when the nest is empty and the breeding season is complete, when the nest belongs to one of the three non-protected non-native species, or when you have a valid USFWS depredation permit authorizing removal.

The clearest legal window is after the breeding season concludes and before the next nesting season begins. In most of the continental US, nesting season for common songbirds runs roughly from April through August, with some variation by species and region. Late fall and winter are the safest removal periods for most nest situations.

Think of it like a parking restriction that lifts at a specific time. The restriction on touching an active nest is total during the nesting period, the same way you cannot park during street cleaning hours. But once that period ends and the nest is empty, the restriction lifts completely for most species.

Frequently Asked Questions

Is it illegal to move a bird’s nest in the United States?

Yes, moving an active bird’s nest belonging to a protected species is illegal under the Migratory Bird Treaty Act (16 USC 703).
Over 1,000 native North American bird species are protected, making most bird nests you encounter covered by federal law.
Penalties include fines up to $15,000 and up to six months imprisonment for misdemeanor violations.
Empty nests from completed breeding seasons can generally be moved without legal consequences.

Can you remove a bird’s nest from your house legally?

You can remove a bird’s nest from your house legally if the nest is empty and the breeding season is over, if the nest belongs to a house sparrow, European starling, or rock pigeon, or if you have a USFWS depredation permit.
Property ownership does not override the Migratory Bird Treaty Act; federal law applies regardless of where the nest is located.
The safest legal approach is to wait until late fall or winter when breeding is complete and the nest is fully vacated.
If the nest is in a genuinely dangerous location, contact USFWS for guidance on emergency situations.

What happens if you move an active bird’s nest?

Moving an active bird’s nest containing eggs or chicks of a protected species violates the Migratory Bird Treaty Act.
If discovered, USFWS can investigate and refer the case for federal prosecution.
In practice, most individual homeowner violations result in warnings rather than prosecution, but criminal penalties of up to $15,000 and six months imprisonment are legally available.
Practically, moving an active nest almost always causes nest failure because parent birds typically abandon relocated nests.

Which birds’ nests are not protected by federal law?

Three species are explicitly excluded from MBTA protection: the house sparrow, the European starling, and the rock pigeon.
All three are non-native invasive species introduced from Europe, and Congress specifically excluded them when updating the MBTA’s coverage.
Their nests, eggs, and chicks can be legally removed at any time without a federal permit.
All other native North American bird species, including common backyard birds like robins, finches, and doves, are fully protected.

How do you get a permit to remove a protected bird’s nest?

A depredation permit authorizing removal of a protected nest is issued by the US Fish and Wildlife Service Migratory Bird Permit Office.
To qualify, you must demonstrate a specific documented conflict, such as a safety hazard, that cannot be resolved by less disruptive means.
Mere inconvenience, such as a nest on your porch, typically does not qualify for a depredation permit.
Contact your regional USFWS Migratory Bird Permit Office to begin the application process and describe your specific situation.

Closing

Bird nest law is one of those areas where most people are surprised to learn how strict and far-reaching federal protection actually is. The Migratory Bird Treaty Act covers over 1,000 species, and its protections apply to your private property just as much as to any public land.
