What Are Javelinas? The Desert’s Misunderstood “Wild Pigs?”
What are javelinas
If you live in Arizona, chances are you’ve seen or heard about javelinas roaming neighborhoods, especially at dawn or dusk. But what exactly are these animals—and are they dangerous?
Javelinas, officially known as collared peccaries, are often mistaken for wild pigs. However, they’re actually a completely different species native to the Americas.
@stmblog They look like pigs… but they’re not 🐗❌ Meet Arizona’s javelinas! hhtps://stmdailynews.com #Javelina #ArizonaWildlife #PhoenixAZ #DesertLife #WildlifeFacts #NowYouKnow #STMdailynews #UrbanWildlife #DidYouKnow #NatureExplained ♬ original sound – STMDailyNews
Not a Pig: Meet the Collared Peccary
The collared peccary (Pecari tajacu) is a small, hoofed mammal with a stocky build and coarse, bristly fur. They get their nickname “javelina” from Spanish, meaning “little javelin,” referring to their sharp tusks.
- Length: 3–4 feet
- Weight: 40–60 pounds
- Color: Gray to black with a lighter “collar”
- Distinct trait: Strong musky odor from a scent gland
Where Do Javelinas Live?
Javelinas thrive in desert environments and are commonly found across Arizona, including the Phoenix metro area. As urban development expands, encounters with humans have become more frequent.
Behavior: Why You See Them in Groups
Javelinas are social animals that travel in groups called “squadrons,” typically made up of 6 to 12 individuals. These groups help protect them from predators and navigate their environment.
They are most active during cooler parts of the day—early morning and evening—especially during Arizona’s hot summers.
What Do Javelinas Eat?
Despite their tough appearance, javelinas are herbivores. Their diet mainly includes:
- Prickly pear cactus (a favorite)
- Mesquite beans
- Roots and desert vegetation
Are Javelinas Dangerous?
Javelinas are generally not aggressive toward humans, but they can become defensive if they feel threatened—especially if they are protecting their young or are approached by dogs.
Important safety tips:
- Do not feed javelinas
- Keep pets on a leash
- Secure trash and outdoor food sources
- Give them plenty of space
Why Are They Showing Up in Neighborhoods?
Urban expansion into desert habitats has increased human-wildlife interactions. Easy access to food—like garbage, pet food, and landscaping plants—also attracts javelinas into residential areas.
Final Thoughts
Javelinas are an important part of the desert ecosystem and usually pose little risk when left alone. Understanding their behavior is the key to peacefully coexisting with these unique animals.

Lifesum Survey: 90% Say Ultra-Processed Foods Are Engineered to Be Hard to Stop Eating
A new nationally representative survey from health app Lifesum suggests Americans increasingly view ultra-processed foods (UPFs) as more than a “willpower” issue. The research, based on responses from 2,000 U.S. adults, found 90% believe UPFs are intentionally engineered to be hard to stop eating—while 81% say they’ve personally felt unable to stop once they start.
Ultra-Processed Foods Under Fire: New Data Shows Regret, Loss of Control, and Calls for Regulation
The survey also points to a widespread “control and regret” loop: 67% report they’ve tried and failed to cut back on certain ultra-processed foods, and 80% say they feel regret or frustration after eating them. The findings land as UPFs remain a dominant part of the American diet—federal dietary data indicates more than half of calories consumed in the U.S. come from ultra-processed foods, and high consumption has been linked in multiple studies to higher risks of obesity, type 2 diabetes, and cardiovascular disease.
Lifesum says the data reflects shifting public attitudes toward stronger oversight. In the survey, 81% support clearer warning labels on ultra-processed foods, 59% support restrictions on marketing, and 47% support regulation similar to tobacco or alcohol. The release also cites a recent report from researchers at Harvard University, the University of Michigan, and Duke University arguing that UPFs share similarities with cigarettes—such as engineered reward pathways and marketing designed to drive repeat consumption—strengthening the case for tighter regulation.
What to watch for
- Labeling momentum: With 81% backing warning labels, expect more debate over front-of-package disclosures and clearer definitions of “ultra-processed.”
- Marketing restrictions: The 59% support level signals potential policy focus on advertising practices—especially around kids and high-frequency digital targeting.
- Regulation framing shift: The 47% support for tobacco-style rules suggests UPFs may increasingly be discussed as a public health and consumer protection issue, not just nutrition advice.
- Scientific scrutiny vs. industry response: As more researchers compare UPFs to cigarettes, watch for counter-messaging from food manufacturers and lobbying around how UPFs are categorized.
- Consumer behavior tools: Demand may grow for evidence-based guidance and tracking tools (apps, labeling systems, education campaigns) that help people reduce UPF intake without relying solely on self-control.

“The Woman Who Invented the Home Security System”
Before smart homes, Marie Van Brittan Brown invented the first home security system in 1966—pioneering safety tech that still protects millions today.

🚨 Before Ring, There Was Marie Van Brittan Brown
Long before smart doorbells and mobile alerts became the norm, a nurse from Queens was already thinking ahead.
In 1966, Marie Van Brittan Brown, a Black woman living in New York City, felt unsafe in her neighborhood. Her husband, Albert, worked late hours, and she was often home alone. With crime on the rise and no real way to know who was at the door, she took matters into her own hands.
So she did what few people would think to do:
Home Security System
She invented the modern home security system.
🛠️ How It Worked
Marie and Albert Brown designed a closed-circuit television system with:
A camera mounted on the door Peepholes at different heights A live-feed monitor inside the home A microphone for two-way communication And a panic button to instantly alert the police.
In 1969, they were granted U.S. Patent No. 3,482,037, and that system laid the foundation for many of today’s smart home security tools.

🔄 Lasting Impact
Marie’s invention wasn’t just revolutionary—it was personal. Her system was designed for peace of mind, especially for women and families in vulnerable communities. Today, elements of her design show up in everything from Ring and Nest to intercom-equipped apartment doors.
She didn’t just protect her home—
she helped create the smart home.

Forgotten Genius Friday: The Legacy of Thomas Jennings — America’s First Black Patent Holder
Discover how Thomas Jennings, the first African American to receive a U.S. patent, revolutionized garment care with his dry-cleaning invention and supported abolitionist causes.
In the early 19th century, long before modern dry cleaners lined city streets, one man quietly transformed how Americans cared for their clothing. His name was Thomas Jennings—a tailor, entrepreneur, and trailblazer whose innovation would earn him a historic place in U.S. history.
Breaking Barriers in a Divided America
Born in 1791 in New York City, Jennings lived in an era when opportunities for African Americans were severely limited. Yet he built a successful tailoring business, gaining a reputation for craftsmanship and attention to detail.
At the time, cleaning delicate garments—especially wool—was a persistent challenge. Traditional washing methods often damaged fabrics, leaving customers frustrated and tailors searching for better solutions.
Jennings saw not just a problem, but an opportunity.
The Invention of “Dry Scouring”
In 1821, Jennings developed a cleaning method he called “dry scouring,” a precursor to modern dry cleaning. Unlike water-based washing, his technique used chemical solvents to remove dirt and stains without harming fabric fibers.
That same year, he achieved a groundbreaking milestone: Jennings became the first African American to receive a U.S. patent.
This was no small feat. Patent laws at the time largely excluded enslaved individuals, and systemic racism made legal recognition difficult even for free Black citizens. Jennings’ success marked a rare and powerful breakthrough.
“His achievement stands in stark contrast to what followed—when laws would deny many Black innovators the right to claim their own ideas.”
Innovation With Purpose
Jennings didn’t just profit from his invention—he used his success to support a broader cause. The income generated from his patent helped fund abolitionist efforts, contributing to the fight against slavery in the United States.
His work intersected with the growing abolitionist movement decades before the American Civil War, demonstrating how innovation and activism often went hand in hand.
Lasting Impact on Modern Life
Today, dry cleaning is a global industry, essential to fashion, hospitality, and everyday life. While technologies have evolved, the core concept Jennings pioneered remains intact.
His legacy can be seen in:
- The modern dry-cleaning industry
- Textile preservation techniques
- The broader recognition of Black inventors in American history
Why Thomas Jennings Still Matters
Jennings’ story is not just about an invention—it’s about access, perseverance, and impact. At a time when the odds were stacked against him, he secured intellectual property rights, built a business, and used his platform to support social change.
For today’s innovators, his journey underscores a powerful truth: meaningful breakthroughs often come from those willing to challenge both technical problems and societal barriers.
Final Word
As part of STM Daily News’ Forgotten Genius Friday series, the story of Thomas Jennings serves as a reminder that some of the most influential figures in American innovation history are still waiting to be fully recognized.
His invention didn’t just clean clothes—it helped clear a path for future generations of inventors.
