It’s not just kids who like snow days! Our American bison enjoy romping through and rolling in the snow too. | Bronx Zoo

Our recent snowfall in NYC didn’t stop the bison in their tracks! That’s because bison have evolved to survive some of the harshest conditions in North America. During the winter they grow wooly coats that help insulate them against the cold. They also have thick skin and layers of fat to keep them warm. Once spring arrives, the bison will shed their fuzzy winter coats. | Bronx Zoo

Introduce your kids to our calves and make a sweet summer memory. There are 8 new bison calves plus over 10,000 other animals to discover. | Bronx Zoo

You’re already familiar with our bison thanks to THE ZOO. Now, 8 purebred bison we received as a gift from the Fort Peck Assiniboine and Sioux tribes are on exhibit. This historic transfer is part of our longtime work on bison conservation. | Bronx Zoo

Important bison calf update! Our first bison calf of the season, born on Earth Day, April 22, is doing great! Currently weighing around 60 lbs, the calf is tiny compared to the adults, who weigh between 1500—2200 lbs for a male and 900—1200 lbs for an adult female. However, bison calves are hardy, and she is settling in well with the herd while staying close to her mom. See if you can spot her in the Bison Exhibit when you visit. | Bronx Zoo

Need an instant mood booster? In this video, watch as our bison calves release some energy. Newborn bison calves can stand within minutes of birth and have the ability to run within just a few hours. They can even reach speeds of 30-35 mph! This rapid development and speed are adaptations which help bison calves evade predators in the wild and keep up with the herd. There are now EIGHT baby bison born this spring around the exhibit! See if you can spot all the new additions to the herd! | Bronx
