The Problem

Canada Geese.
A $473M problem hiding in plain sight.

Resident Canada goose populations in North America have grown from near-extinction in the 1960s to nearly 4 million birds today — concentrated at the exact places they cause the most damage: airports, golf courses, retention basins, and corporate campuses.

The Species

Branta canadensis maxima — the giant Canada goose.

Once thought extinct, the resident (non-migratory) Canada goose has become one of North America's most successful — and most problematic — wildlife species.

3.7–4.0M

Resident Canada geese in North America (USFWS 2025) — up from ~1.1M in 1990.

14–20 lb

Adult bird weight. A goose ingested into a jet engine causes catastrophic, not nuisance, damage.

1–3 lb/day

Droppings per adult goose. A flock of 50 deposits ~150 lb of waste daily on a golf course or campus lawn.

20–24 years

Lifespan in protected suburban environments. Resident birds do not migrate and habituate to humans within weeks.

The Cost

Quantified damage across four verticals.

$473M+
Annual US aviation bird-strike damage (FAA 2024)
22,372
Wildlife strikes in 2024 — up 14% YoY
74,268
Aircraft downtime hours from wildlife strikes
$300M+
US border-collie wildlife service industry (recurring)

Where the damage happens

Airports

FAA-tracked wildlife strikes, including the 2009 US Airways 1549 Hudson River ditching. 97% of strikes involve birds.

Golf Courses

Damaged greens, fouled cart paths, lost member rounds. GCSAA superintendents report geese as a top-3 vertebrate pest.

Corporate Campuses

Slip hazards, aggressive nesting behavior, water-quality complaints from retention basins.

Municipal Water

E. coli loading in source reservoirs and recreational lakes. EPA-tracked impairments.

Why Existing Methods Fail

Habituation. Cost. Coverage.

✗
Propane cannons & static deterrents. Geese habituate in 3–5 days (Cummings 1995, Crop Protection). Audio scares lose efficacy after the second exposure.
✗
Border collie services. $170K–$190K per site/year. Night-blind. 24/7 coverage is structurally impossible — dogs sleep, handlers go home.
✗
Drone-based deterrence. Licensed pilots required. 5–90 minute battery runtime. No peer-reviewed efficacy data on goose habituation.
✗
Egg oiling & population management. Removed birds are replaced by neighboring flocks within a season. Politically contested with welfare groups.
✗
Reflective tape, scarecrows, fake predators. Static. Habituated to within 72 hours. No measurable long-term reduction.
Regulation

The most permissive federal environment in 30 years.

April 2025 Solicitor's Opinion M-37085: non-lethal autonomous deterrence requires zero federal take authorization under the Migratory Bird Treaty Act. The legal precedent supporting autonomous deterrence platforms is the most permissive since 1995.

FAA and ICAO mandate wildlife hazard management programs at all commercial-service airports. Varia Robotics is positioned as the autonomous, peer-reviewed, non-lethal answer to a regulatory requirement that has, until now, only been served by labor-intensive methods.
