Dear EarthTalk: How are researchers using wildlife to track environmental conditions and monitor climate change?
—Jane P., South Bend, Indiana
Scientists currently rely mainly on a complex network of satellites, ocean buoys, weather stations and balloons to help predict the weather and the effects of climate change, but it might not be the best solution. What if instead of using satellites and weather stations to study the planet, scientists used animals? Imagine a world where a pigeon could help gather information on air pollution.
That world already exists. In Mongolia, pigeons equipped with sensors fly around the capital city of Ulaanbaatar and help measure the air quality. Tagged elephant seals help provide nearly 80% of all available information on ice depth and ocean salinity in Antarctica. Geolocation sensors, often attached to animals via collars or tags, can provide scientists with near endless amounts of information on wildlife and the environment. The sensors, equipped with GPS and other advanced technology, offer a lens directly into the habitats that animals inhabit.
Using wildlife to track environmental conditions only highlights the shortcomings of current methods of collecting climate data. While satellites can gauge temperatures at the surface of a cloud-covered jungle canopy, they cannot reveal the conditions on the ground, not the way that a monkey would be able to. Most weather stations are built on flat land and in developed areas, not in the mountainous regions that are heavily affected by climate change. However, mountain goats or birds with sensors can easily monitor the temperatures of the region. Wildlife geolocation sensors can help fill critical data gaps, particularly in more remote areas of the planet.
Equipping fish, birds, seals and other animals with sensors can offer highly localized and timely data that current tech cannot. The sensors can provide data on animal behavior and migration patterns along with data on environmental conditions impacted by climate change. They can improve scientists’ measurements on air temperature, ocean salinity, air pollution and biodiversity. Rather than using satellites to capture images of the planet’s surface, scientists can study animal decisions and preferred conditions to sense the quality and health of ecosystems. Studying the environmental conditions that drive animals’ movements can offer a lens directly into the habitats themselves.
Thanks to action by the Max Planck Institute of Animal Behavior, thousands of birds and animals are already outfitted with sensors, but the opportunities that wildlife tracking presents have not yet been fully realized. To implement geolocation sensors on a wider scale there must be collaboration between government agencies and the science community. The data that the sensors could provide the scientific world would be more accurate, timely, cost-effective and non-invasive than the more popularized current methods. Wildlife tracking provides an opportunity for revolution in conservation efforts, environmental monitoring and research on climate change.

LAKEVILLE — Rhys V. Bowen, 65, of Foxboro, Massachusetts, died unexpectedly in his sleep on Sept. 15, 2025. Rhys was born in Sharon, Connecticut, on April 9, 1960 to Anne H. Bowen and the late John G. Bowen. His brother, David, died in 1979.
Rhys grew up at The Hotchkiss School in Lakeville, where his father taught English. Attending Hotchkiss, Rhys excelled in academics and played soccer, basketball, and baseball. During these years, he also learned the challenges and joys of running, and continued to run at least 50 miles a week, until the day he died.
In 1982 after graduating summa cum laude from Harvard College, Rhys returned to Hotchkiss to teach biology, where he met his wife of 35 years, Rebecca (Becky) Snow. After two years of teaching, he worked at a research field site in Borneo, then went on to the University of California, Davis where he earned a PhD in Animal Behavior in 1995.
Rather than follow an academic tenure track, Rhys preferred the solitary focus of field ornithology, and he spent several decades researching the ecology of bird species in California and on Cape Cod and the Islands. Rhys believed passionately in supporting biodiversity through habitat preservation. His proudest achievements, therefore, came through his work for the Lakes Region Conservation Trust, in New Hampshire, where he served on committees and the Board of Trustees for twenty years, including three years as Chair.
Deeply intellectual and curious, Rhys learned Homeric Greek so he could read The Odyssey and The Iliad in their original language. An amateur Melville scholar, he would wax poetic about reading Moby-Dick for the umpteenth time.Rhys’s spirit was filled by the performing arts. Concerts by the Handel and Haydn Society and Boston Early Music Festival often brought tears to his eyes, while Boston Bluegrass Union shows delivered toe-tapping fidgetiness.
Rhys will be missed by his wife, Becky Snow, his mother, Anne Bowen, extended family, friends, and anyone who had the pleasure of knowing him.
A service will be held at The Hotchkiss School chapel on Saturday, Nov. 15, 2025 at 1 p.m..
In honor of Rhys’s memory, donations can be made to the Lakes Region Conservation Trust.
LAKEVILLE — Kelsey K. Horton, 43, a lifelong area resident, died peacefully on Saturday, Sept. 27, 2025, at Norwalk Hospital in Norwalk, Connecticut, following a courageous battle with cancer.

SHARON — On Sept. 27, Eliot Warren Brown was shot and killed at age 47 at his home in New Orleans, Louisiana, in a random act of violence by a young man in need of mental health services. Eliot was born and raised in Sharon, Connecticut, and attended Indian Mountain School and Concord Academy in Massachusetts. He graduated from the School of the Art Institute of Chicago. He and his wife Brooke moved to New Orleans to answer the call for help in the aftermath of Hurricane Katrina and fell in love with the city.
In addition to his wife Brooke, Eliot leaves behind his parents Malcolm and Louise Brown, his sisters Lucia (Thaddeus) and Carla (Ruairi), three nephews, and extended family and friends spread far and wide.
Normally at this point one might list some interests, but in Eliot’s case, it’s easier to list what he wasn’t interested in: watching sports.
Eliot made a living as a fine craftsman and carpenter, but at heart he was an artist. He was well versed in music, painting, literature, biking, travel, Mardi Gras costumes, poker, pranks, street performance and on and on and on.Having previously hiked the entire Camino de Santiago in Spain and Portugal, he recently achieved another dream of summiting the highest stratovolcano in North America.
Eliot’s creative ability was astounding. His creations were designed to bring joy to others. He didn’t seek recognition or praise, and a large part of his work was anonymous. Pieces of art would appear in the community, encouraging people to think, connect and enjoy.
From the precociously funny and determinedly defiant boy that grew up in the Northwest corner of Connecticut, Eliot grew into a brilliant, gentle souled, boundlessly creative, ever mischievous, perpetually scraggly, and astoundingly wise and caring man who made an indelible impact on those who were lucky to have him in their lives.
In honor of Eliot, please consider making donations to organizations that work to end gun violence, support the arts, or provide mental health services. A service will be held at the Congregational Church in Salisbury on Sunday Oct. 26 at 2 p.m.
SHARON — Randall “Randy” Osolin passed away on Sept. 25, 2025, at the age of 74. He was born on Feb. 6, 1951, in Sharon, Connecticut to the late Ramon (Sonny) and Barbara (Sandmeyer) Osolin.
He was a dedicated social worker, a natural athlete, a gentle friend of animals, an abiding parish verger, an inveterate reader, and an estimable friend and neighbor. He was a kind-hearted person whose greatest joy was in helping someone in need and sharing his time with his family and good friends.
He was the beloved husband of Karen LaChance Osolin; the loving brother of Bruce Osolin and the late Gail Osolin Leo; the devoted uncle of Kyle and Andrew Osolin and Taylor LaChance; the brother-in-law of Debra LaChance; and the cousin of Brenda Curran, Jay Pickering and Audra Salazar.
To honor Randy’s memory, do a good deed for another or send a donation to the Little Guild, 258 Sharon-Goshen Road, West Cornwall, CT 06796. The Kenny Funeral Home has care of arrangements.
