The mountain lion known as P-47 survived fires, freeways and hostile ranchers. But in March, the 3-year-old big cat—tracked by California biologists since his kitten days—succumbed to a hidden hazard: an insidious form of food poisoning. Six anticoagulant compounds—chemicals used to kill rodents...

As my beloved seedlings languished untouched on the display table, I improved my sales pitch: “Would you like a late-flowering thoroughwort to help migrating butterflies refuel? What about an aster that’s the only pollen source for some bee species?” But unlike the animals who would devour these...

It’s a peculiar rite of modern homeownership: Plant a tulip bulb in autumn, cage or spray it to deter nibblers, admire its fleeting blooms a few months later, let it rot in soil ill-suited to its needs and repeat the whole cycle again the following year.

As my neighbors and I stood 10 feet apart and swapped tips for scavenging kitchen staples this spring, the wilder residents of our community shared no such concerns. Squirrels twirled maple seed clusters like bouquets to reach every tidbit. Bumblebees made a mockery of social distancing in their...

The delegate seemed ready to pick a fight, already having mocked a proposed plastic bag ban and other pro-environment bills on the day’s agenda. As I finished my testimony in support of wildlife-friendly plantings, I steeled myself for a heated debate. But on that gray afternoon in February 2020...

It seemed like a good idea at the time: Buy a house with a two-acre property, let our energetic herding dog have the run of the place and spend blissful summer days digging side by side in the dirt with her. And it was blissful, watching Mattie carve out her napping spots behind the ferns and tall...

Following one former lab worker's path to advocacy.

How to spur wildlife-friendly projects in your community.

The woodland phloxes bring the heavenly scents of spring, and the fireflies bring the sparkling lights of summer. Even in the depths of winter, cardinals, white-throated sparrows, northern flickers, mourning doves and squirrels bring all the music and entertainment we could ever need—right in front...

Somewhere toward the end of the last ice age, we formed an alliance with wolves: Maybe the ancestors of dogs got food scraps while our own ancestors gained protection from predators and other humans. These social species eventually collaborated on a vast scale, possibly even hunting woolly mammoths...

Teddy was never meant to have a name. He was born a number, just one of tens of thousands of dogs—mostly beagles like him, chosen for their trusting, docile nature and compact size—bred in the United States for use in experiments each year. Teddy was meant to live and die in a laboratory, without...

Sitting on her porch in the desert one afternoon while recovering from surgery, Christine Hass closed her eyes. The operation to fix her detached retina had been difficult, and she sought respite from the lingering pain. “Suddenly I could hear all the birds singing. It was March—the migrants were...

Goblin might not have lasted much longer at Tim’s Reptiles and Exotics in Pulaski County, Kentucky. The sulcata tortoise was one of about 150 animals rescued in September from nightmarish conditions at the pet store when local police arrested the store operator on 19 counts of animal cruelty...

Walk into a roadside restaurant after a long day on the highway, and you can practically taste your meal before sitting down. The familiar smells of fresh-baked pie and salty fries need little introduction en route to your belly. That sensory experience is similar for wildlife coming upon lush...

While soaking her raised beds in preparation for tomato planting last summer, Gail Goldman was startled to see a tiny, waterlogged creature pop up out of the soil. Later another one briefly poked out his head. “Basically, I was watering shrews,” the Seattle gardener says of her foiled vegetable...

It starts out mildly enough: Heading to work on the subway, you realize you forgot your wallet. No big deal, you think. I’ll borrow money to get home. Soon the lights go out and the train hurtles toward the sky, speeding through the atmosphere. Time passes—it’s hard to tell how long. The subway is...

Pop quiz: What’s the best way to help butterflies in your backyard? If you answered “Plant butterfly bush,” you’re in good company. A recent survey of my gardening friends elicited the same response from more than a few. It’s easy to understand why: Aside from its self-reinforcing moniker, the plant...

WASHINGTON —Today, the Humane Society of the United States and Humane Society Legislative Fund filed a petition with the Food and Drug Administration requesting that the agency updates regulations to make clear that animal testing is not legally required for drug approval. The petition also requests...

As the world stopped turning and the fires started burning this summer, there was a hole in my heart that only a chipmunk could fill. Shy at first, the distant object of my affection warmed to my presence, until one day we even had breakfast on the patio together: a coffee for me and a snail for Mr...

WASHINGTON - The Humane Society of the United States released today the results of a disturbing undercover investigation into two wildlife killing contests in Frederick County and in Waldorf, Maryland.
