Yes, you can still have a tree taken down during nesting season in the Treasure Valley, as long as the tree doesn’t hold an active nest with eggs or chicks in it. The federal rule behind bird nesting season tree removal in Idaho, the Migratory Bird Treaty Act, doesn’t shut down tree work from March through August. It protects occupied nests, not the calendar.
That distinction gets lost a lot. Homeowners hear “nesting season” and assume every tree service in Ada and Canyon County goes quiet for six months. Getting it wrong in either direction costs you: a needless delay on a project that could have proceeded, or a federal violation on a tree that should have waited five weeks.
Not sure if the tree you need removed has an active nest right now? Request a pre-removal assessment or call (509) 351-8404, and we’ll check the canopy before anyone starts a saw.
The Quick Answer
| Situation | What the law says |
|---|---|
| Tree has no active nest | No federal restriction. Remove it any time of year. |
| Active nest with eggs or chicks | Illegal to destroy under the Migratory Bird Treaty Act (16 U.S.C. §§ 703-712). |
| Old, empty nest from a past season | Generally not protected once the birds have left, with the exception of eagle nests. |
| Nest of a non-native species (European starling, house sparrow, rock pigeon) | Not protected by the Act. |
| Idaho’s practical nesting window | Roughly March through August, with some raptors and owls starting in February. |
| Federal permit to remove a tree with an active songbird nest | Does not exist for ordinary homeowners. The only lawful option is usually to wait. |
What the Migratory Bird Treaty Act Actually Covers
The Migratory Bird Treaty Act is a 1918 federal law, codified at 16 U.S.C. §§ 703-712, that makes it illegal to kill, capture, or “take” a protected migratory bird, or to destroy its nest, eggs, or young, without a federal permit. It covers more than 1,000 native bird species, from robins and finches to hawks and herons, and is enforced by the U.S. Fish and Wildlife Service, not the City of Boise or Ada County.
The part that matters for tree removal is narrow: the Act protects a nest while it’s in use, meaning while it holds eggs or young that haven’t fledged yet. An empty nest left over from last spring generally isn’t protected once the birds are gone. Bald eagle and golden eagle nests are the one exception, since a separate federal law, the Bald and Golden Eagle Protection Act, protects an eagle nest even when it’s empty, and removing one requires its own federal permit regardless of the season.
Not every bird you’ll see in a backyard tree counts, either. European starlings, house sparrows, and rock pigeons are non-native species and aren’t covered by the Act at all.
Idaho’s Bird Nesting Season Runs Roughly March Through August
Most songbird species in the Treasure Valley build nests, lay eggs, and fledge young somewhere between April and July. A handful of raptors and owls start earlier, sometimes as early as February, which is why arborists in Idaho generally treat March through August as the safe window to assume a nest could be active. Outside that window, from roughly September through February, the odds of an occupied nest in a residential tree drop close to zero.
That window is a planning guideline, not a legal deadline. It exists because checking a tree in June without accounting for an early-nesting hawk is how homeowners end up with a problem they didn’t see coming. It doesn’t mean every tree removal scheduled in May needs to be pushed to September.
What the Law Does Not Require of a Private Homeowner
The Migratory Bird Treaty Act does not require a homeowner to get a permit before removing any tree, and it does not impose a blanket ban on tree work during nesting season. It does not require hiring a wildlife biologist to inspect a tree with no visible nest.
It also does not override the City of Boise’s separate street-tree permit process, a local rule about which trees you’re allowed to remove that has nothing to do with birds.
What it actually requires is simpler and stricter at the same time: don’t destroy a nest that currently has eggs or chicks in it. A homeowner who has an arborist check the canopy, finds nothing active, and proceeds with removal in June has done everything the law asks. One who cuts into a nest full of hatchlings without looking first has committed a federal misdemeanor, even without meaning to.
Violations can carry fines running into the thousands of dollars plus potential jail time, though in practice enforcement focuses on large-scale or clearly reckless harm rather than a single overlooked backyard nest. That’s not a loophole. It’s a reason to check first, not a reason to skip checking.
Our guide on tree removal permits in Boise covers the separate, local side of this question: which trees the city lets you take down and what paperwork that requires.
When a Hazard Tree Overrides the Calendar
Nesting season doesn’t suspend safety. If a tree is actively failing, cracked at the base, split by wind, or leaning onto a structure, that hazard doesn’t wait for chicks to fledge. A genuinely dangerous tree can and often should come down immediately, nest or no nest, because the alternative risk to people and property is the greater concern.
A scenario from Garden City: after a spring windstorm cracked a large cottonwood down its trunk, a property manager found an active robin’s nest with three eggs about 20 feet up, right where the crew needed to cut. The tree was already leaning toward a detached garage and could have come down on its own within days. The removal proceeded that week, documented as an emergency hazard, at a cost of roughly $2,800 for the size and access involved. Waiting wasn’t a realistic option once the trunk had split.
Compare that to a more typical case. A homeowner in Meridian wanted a leaning silver maple removed in early May, mostly for aesthetic reasons and a little for peace of mind. An arborist found an active nest with eggs partway up the canopy but confirmed the tree itself wasn’t an immediate hazard. The removal, priced at roughly $1,200 for a medium tree, was rescheduled about five weeks out once the nest was confirmed empty. Same job, same price, just a different calendar date.

How to Check for an Active Nest Before You Cut
Before any removal scheduled between March and August, a quick canopy check settles the question. Look for adult birds flying to and from the same spot repeatedly, listen for chick calls from inside the foliage, and scan for visible nest material in the fork of major branches. None of that requires a specialist, though an ISA-certified arborist doing the pre-removal walkthrough will typically spot it as part of the assessment anyway.
If you find an active nest, the practical fix is timing, not paperwork. Most songbird nests run their full cycle, building through fledging, in about four to six weeks. Marking the calendar and coming back once the young have left is almost always cheaper and simpler than trying to work around an occupied nest mid-project. If you’re unsure whether what you’re looking at is active or last year’s leftovers, that’s exactly the kind of judgment call worth a tree health assessment rather than a guess from the ground.
Homeowners tackling their own tree work face this same question with less canopy-reading experience, one more reason a DIY removal in nesting season carries extra risk. Skip chainsaw work above shoulder height, stay off a ladder in the canopy, and keep clear of anything near a power line. A tree that could reach a structure if it fails needs a professional look, not a weekend project. Our comparison of DIY tree removal versus hiring a professional covers the other risks worth weighing first.
If you’d rather have someone else make the call, our guide on how to hire a tree service in Boise and our tree removal page cover what to ask before you book the work. Delaying a non-urgent removal by five or six weeks rarely changes the price much, and our cost calculator can help you sanity-check that against your own project.
Frequently Asked Questions
Can I trim a tree during nesting season if I’m not removing the whole thing?
Yes, as long as the pruning doesn’t disturb an active nest with eggs or young in it. The same rule applies to trimming as to full removal: check the canopy first, and if there’s no occupied nest in the section you’re cutting, the work can proceed.
What if I accidentally destroy a nest I didn’t know was there?
The Migratory Bird Treaty Act doesn’t require intent to result in a violation, but in practice, enforcement against a homeowner who made a reasonable effort to check beforehand is rare. Documenting that an arborist inspected the tree and found nothing active is the best protection if the question ever comes up.
Does this rule apply to a dead or clearly hazardous tree?
The nesting protection still technically applies to an active nest in any tree, dead or alive, but genuine hazards that threaten a structure or a person generally justify immediate removal regardless of the season. That’s a judgment call worth documenting with photos and, where possible, a professional assessment at the time.
Do I need a permit from the city or the state to remove a tree because of a bird nest?
No. There’s no city, state, or county permit tied to bird nesting specifically. The City of Boise’s street-tree permit process is a separate local rule about tree removal generally, and it applies year-round independent of whether a nest is present.
How do I know if birds nesting in my tree are a protected species?
Assume any wild native bird you see, songbirds, hawks, owls, herons, is protected unless you can positively identify it as a European starling, house sparrow, or rock pigeon, the three common non-native species excluded from the Act. When in doubt, treat the nest as active and protected until you’ve confirmed otherwise.
Nesting season is a timing question, not a reason to cancel a tree removal you actually need. Call (509) 351-8404 or reach out here and we’ll check the canopy, tell you honestly whether a nest is in the way, and either schedule the work now or give you the date it can happen.
