GPS Instead of Cowbells
Modern technology for animal welfare
Cowbells expose cattle to noise levels up to 113 dB, equivalent to a chainsaw, for months on end. Scientific studies show this causes stress, reduced noise reactivity, and behavioral changes.
Modern GPS collars and drone monitoring now offer humane alternatives for tracking cattle. With this petition, we call on the German federal government to promote the transition to GPS tracking and prioritize animal welfare.
Sign the PetitionWhere Cattle Wear Bells
Each summer, approximately 53,000 cattle are driven up to Bavaria's 1,450 alpine pastures (Almen), where they graze freely for up to six months, wearing bells the entire time. These cattle are split roughly evenly between Upper Bavaria and the Allgäu region.

The Proposal: Replace Cowbells with GPS Tracking
Cowbells were used to locate cattle on Alpine pastures. Today, silent and animal-friendly alternatives exist. We demand a transition to GPS tracking instead of cowbells.
Cows have superior hearing sensitivity. Studies show: reduced feeding, less rumination, and no habituation to bell noise.
Residents and tourists experience constant bell noise — courts have already ordered bell removal in multiple cases.
Modern GPS trackers provide real-time location data via smartphone app — more effective than bells, especially in fog and at night.
Animal Suffering: The Hidden Cost of Tradition

"A bell heavier than one-thousandth of the animal's weight is too large — it is animal cruelty."
— Samuel Büechi, President, IG Stiller, 2024 · SRF (translated)
"To subject an animal to something like this purely for tradition is completely unacceptable."

Cows' Hearing
Cattle hear far better than humans — a loud bell right next to their ear is far more distressing than we might assume.
Cow Hearing vs. Human Hearing
Frequency Range
Minimum Detectable Sound
Cows can hear sounds that are too quiet for humans to perceive, making them more vulnerable to loud noise exposure. [Heffner & Heffner, 1983]
A cowbell reaching up to 113 dB right next to their ear is therefore an extreme burden for cattle.
Hear it yourself
Imagine hearing this noise 24 hours a day, 7 days a week.
How Loud Are Cowbells?
At 20 cm (the distance between a cowbell and the cow's ear), noise levels reach 90-113 dB. This exceeds legal workplace noise limits in most countries. [Source]
Studies: Bells Alter Cow Behavior
Researchers at ETH Zurich conducted two studies to investigate how cowbells affect cattle behavior and health:
2015 Study: Effects of Cowbells
Johns et al., PLOS ONE (2015) · 19 Brown-Swiss cows · 3 days per treatment
ETH researchers investigated how wearing cowbells affects dairy cow behavior. They compared cows without bells to cows wearing functional bells (5.5 kg, 90–113 dB).
* statistically significant
Key finding: Lying (day 3)
Only the functional bell (with noise) reduced lying time – by almost 4 hours on day 3. This suggests a delayed, cumulative effect of noise.
No habituation observed after 3 days
The study shows: Cows do not habituate to bells. Weight alone significantly impairs feeding and rumination. Noise additionally reduces lying time.
2017 Follow-up: Long-term Effects of Bell Exposure
Johns et al., Frontiers in Veterinary Science (2017) · 96 cows · 24 Swiss farms
Two years later, the researchers investigated whether cows with regular bell experience react differently to acoustic stimuli than cows without bell experience.
Normal avoidance reaction to unfamiliar sounds (pink noise at 65 & 85 dB)
67% less avoidance reaction to unfamiliar sounds (pink noise at 65 & 85 dB)
Interpretation
"Altered acoustic perception"
Cows that regularly wear bells show an altered response to acoustic stimuli. The researchers recommend bells with lower amplitude.

Ceremonial Cruelty

The Almabtrieb: When Tradition Amplifies Suffering
Each autumn, the Almabtrieb (also called Viehscheid in the Allgäu) marks the ceremonial descent of cattle from alpine pastures. Thousands gather to watch as decorated cows parade through villages. But behind the festive atmosphere lies an overlooked cruelty.
The lead cow, called the Kranzkuh ("wreath cow"), is forced to wear an extra-large ceremonial bell that can weigh 5–8 kg or more. These oversized bells produce even louder noise and place significant strain on the animal's neck.
Adding to the stress, the Almabtrieb is a crowded public event with hundreds to thousands of cheering spectators, music, and commotion – an overwhelming environment for animals accustomed to quiet alpine pastures.
Community Impact: Beyond the Pastoral Idyll
While cowbells may evoke romantic images of Alpine meadows, the reality for nearby residents is constant noise pollution throughout the grazing season. The sound that tourists find charming becomes a daily burden for those who live with it.

Chronic Sleep Deprivation: 6 Months of Disrupted Rest
During grazing season, residents near Alpine pastures experience constant bell noise from early morning until dusk, sometimes through the night when cattle graze nearby. Unlike traffic noise that follows predictable patterns, cowbells ring irregularly, making it impossible to adapt.
Chronic sleep deprivation health risks:
- Heart disease
- Obesity
- Diabetes
- Weakened immunity
- Depression
- Anxiety
- Memory problems
- Reduced focus

The Tide is Turning
A decade of legal progress across the Alps
In 2015, animal rights activists including the German Animal Welfare Society called for a ban on cowbells in Bavaria. The campaign generated significant media attention but was rejected by the Bavarian government.
Agriculture Minister Helmut Brunner dismissed the concerns, arguing that electronic tracking technology was "not yet technically mature and still in the trial phase."
That was more than 10 years ago. Today, GPS collars, virtual fencing systems, and drone monitoring are mature, commercially available technologies used by farmers worldwide. The minister's objection is now obsolete.

Courts Have Ordered Bells Removed
Erlkam, Upper Bavaria
Miesbach district court issued an injunction banning bells within 100m of a residence between 7pm–7am. The resident measured noise at 109 dB, equivalent to a pneumatic drill, while local limits are 60 dB (day) and 45 dB (night). Violations carry a €250,000 fine or 6 months jail.
Stallhofen, Austrian Alps
Judge ruled that cattle with bells in fenced meadows "disturbs the nocturnal peace of neighbors" and ordered bells removed. The court rejected claims that bells are a traditional feature of rural areas.
Zurich Oberland
Court inspection found "even at 80 metres, residents were exposed to loud noise." A complete ban was ordered. The farmer had appealed a nighttime-only restriction, but the court imposed a total prohibition instead.
Holzkirchen, Bavaria
After 5 years of litigation, a settlement was reached in May 2020. The couple sued citing sleep deprivation and depression. OLG München dismissed appeals (April 2019), and BGH rejected further appeal. Final settlement: only 3 cows may wear bells, and only in a designated area of the meadow away from the property line.
Zwischenwasser, Vorarlberg
A vacation rental owner sued because guests were leaving early due to cowbell noise. The hotelier's lawyer cited ETH Zurich research showing bells reach 100–110 dB. Settled out of court: cows received GPS trackers instead of bells, proving modern alternatives work.
Canton Aargau
Court ruled it was wrong to exclude cowbells from nighttime noise regulations. The farmer must now remove bells after 10pm. This precedent confirms that cowbells are subject to the same noise laws as other disturbances.

Frequently Asked Questions
Isn't this just an attack on tradition?
▼
Traditions evolve as our understanding grows. Many practices once considered normal, like bear-baiting or cock-fighting, were abandoned when we recognized the harm they caused. Cowbells served a practical purpose before GPS and modern tracking, but we now have better alternatives that don't compromise animal welfare.
Wouldn't this be too expensive for farmers?
▼
GPS tracking collars are now affordable and reliable. They provide real-time location data via smartphone apps, which is more effective than listening for bells, especially in fog, bad weather, or across large distances. Many modern farms already use this technology.
Is there really scientific evidence of harm?
▼
Yes. Peer-reviewed studies published in journals like PLOS ONE and Frontiers in Veterinary Science have documented that bell-wearing cows show reduced feeding and rumination times, with no evidence of habituation even after months of exposure. The noise levels (90-113 dB) exceed occupational safety limits for humans.
What about the economic impact on tourism?
▼
While cowbells are part of Bavaria's pastoral image, they are not essential for tourism. Visitors come for the Alps, the food, the culture, and the landscapes, not specifically to hear bells. Farms could display bells as heritage artifacts while using humane tracking methods in practice. Germany could position itself as a pioneer for sustainable and animal-friendly tourism in the Alps, as well as scientifically progressive on animal welfare.
Has any region successfully banned cowbells?
▼
While no region has implemented a full ban, the debate is growing in both Germany and Switzerland. Animal welfare organizations in both countries have called for restrictions, and individual farmers have voluntarily switched to GPS tracking. This petition aims to accelerate that transition through legislation.
Summary
Animal Suffering
- 53,000 cattle wear bells on Bavarian alpine pastures for up to 6 months each year
- Bells produce 90–113 dB at ear level, equivalent to a chainsaw or rock concert
- Cattle have superior hearing sensitivity and studies show they do not habituate to the noise
- Scientific studies show bells cause reduced feeding, less rumination, and abnormal head movements
Community Impact
- Residents near grazing areas report sleep deprivation and health issues
- WHO guidelines set nighttime noise limits at 40 dB, yet cowbells exceed this by 50–70 dB
- Courts across Bavaria, Austria, and Switzerland have ordered bells removed in multiple cases
- Tourism operators have sued over guests leaving early due to noise
The Solution
In 2015, the Bavarian government rejected a bell ban, claiming GPS technology was "not yet mature." That was more than 10 years ago. Today, GPS collars, virtual fencing, and drone monitoring are commercially available and used by farmers worldwide.
We call on the German federal government to gradually replace cowbells with GPS tracking and support farmers in transitioning to modern, humane cattle tracking technologies.
