The bears on our Polar Bear Tracker were on the move this fall! Some were waiting for freeze-up, while pregnant females entered their maternity dens. Learn about what each of these bears have been up to as they follow the changing sea ice while hunting seals: pbears.org/4rnQ43n

Recent research shows that polar bears on the sea ice show more variation in weight gain on the sea ice than previously thought, which may make them more vulnerable to loss of summer sea ice. Learn more ⬇️ https://pbears.org/42E814u

Made it to the weekend 🙌🏻 #TGIF #FriYAY

Want to teach your students or kids about polar bears? Check out our Paws up for Polar Bears unit! This unit focuses on polar bear ecology, the Arctic, and the impacts of climate change on habitats and natural processes, all while instilling a stewardship ethic. https://pbears.org/3SvXbbq

We're thrilled to share that our “Bear-dar” early detection radar is currently being used on a remote research station in the Canadian high Arctic. “We’re trying to give people tools to prevent conflicts,” PBI's Elbert Bakker told @gearjunkie.bsky.social. https://pbears.org/49ORSeH

The silliest little cub to brighten your Monday feed.

Two years in a row, photographer Chuck Wood has witnessed a polar bear interacting with abandoned fishing nets. In 2024, he witnessed a bear struggling in the water, but it thankfully freed itself. This past fall, a fed on a reindeer stuck in a net. Read Chuck's story, here: pbears.org/4jLUTB8

Hey teachers and educators, looking for curriculum ideas? In our Mom & Me unit, students will learn about the relationship between sea ice and polar bear populations and about the ways climate change impacts the sea ice ecosystem in the Arctic. pbears.org/49CDbcY

Right now, polar bear moms are snug in their dens with their newborn cubs that were born around New Years. How do polar bears know they're pregnant & when to build a den? Polar bear scientist Dr. Thea Bechshoft answers a reader's thoughtful question, below. https://pbears.org/3DO3135

Climate change may be causing some of that ice to injure the feet of polar bears. A 2024 paper found that bears in two of the most northerly populations had suffered lacerations, skin ulcerations, and ice build-up on their feet. Learn more from the paper's lead author: pbears.org/3YtXFkK

Polar bear cubs’ long journey to adulthood begins in the cozy confines of a maternal den, which provide critical shelter to fragile new-born cubs. Learn about the basics of polar bear denning: pbears.org/48mh2PY

Conservation work on one species can benefit others in the same environment. “In most cases, if you do the work necessary to protect the animals at the top of a food web — like the polar bear — then everything below them is going to be protected.” —Dr. John Whiteman pbears.org/meetjohn

Three years ago, Dr. John Whiteman was appointed Polar Bears International’s chief research scientist. We recently talked with John about his role at PBI, what drew him to working with polar bears, and why he is so committed to polar bear conservation: pbears.org/meetjohn

In honor of Polar Bear Week, @jrnymag.bsky.social shared some of the most interesting facts about polar bears! See how many of them you know in the below article.

When researchers first looked at pregnancy rates among the polar bears of Hudson Bay in the early 90s, the results were promising. However, a recent study has uncovered a striking decline. We talked to the study authors about what they’re seeing and why. pbears.org/3JAf1Zo

As the Arctic warms and the sea ice melts, more polar bears are spending more time ashore in more places, and for longer periods. Our coexistence efforts help aim to help keep polar bears and people live safely alongside each other. Learn more below. https://youtu.be/S4qjNYHB2m4

After several years of testing and training the AI, our Bear-dar radar had its first real-world deployment in the Canadian high Arctic this summer! Geoff York spoke with The Weather Channel about this project and how it can help protect communities in the north. https://pbears.org/4oWm7pT
