Sound on to hear bison bellows! 🔊 Mating season is in full swing at Neal Smith National Wildlife Refuge in Iowa. Bison bulls compete for a chance to mate, making deep vocalizations that echo across the prairie. 🎥 Nancy Corona/USFWS | U.S. Fish and Wildlife Service

Bison mating season is still going on in the park. Male bison are particularly aggressive right now, though all bison and other wildlife can be dangerous. Remember to always keep your distance—25 yards from bison and elk; 100 yards from all other wildlife. #Yellowstone #NationalPark #WhatWildlifeDoWednesday #Bison | Yellowstone National Park

WATCH THESE BISON SWIM THE YELLOWSTONE RIVER 👀 This small herd of bison decided to take a nice cold swim this spring (notice the melting snow ❄️ on the riverbank) in the Yellowstone River! Bison are the largest mammal in North America. Male bison (called bulls) weigh up to 2,000 pounds and stand 6 feet tall, while females (called cows) weigh up to 1,000 pounds and reach a height of 4-5 feet. It's hard to believe these large creatures can swim but as you can see from the video they do just fine!
