When I visited Yellowstone in 2016, seeing the American baby bison at play was one of my favorite sightings; I was certainly looking forward to seeing them again in May 2022. They did not disappoint; the first group of bison (Bison bison) that stopped us on the road on Day 1 included a good number of babies.
During our week’s stay in Yellowstone, the weather was very changeable. On one and the same day, we would have snow flurries, cold winds and hours of bright sunshine and balmy warmth leading us to shed warm jackets. That didn’t stop us from seeing bison everywhere though.
As you drive through Yellowstone, your progress is often slowed down or stopped as herds of bison take over the roads. They have the right of way, so cars need to stop as the group walks around the parked vehicles. People are not allowed to get out as the protective parents could seriously harm anyone nearby.
Sitting in your stopped car does give you a good look at the molting adults and cute youngsters as they pass by your window, sometimes within a couple of feet.
Bison are the largest mammals in the USA. They were designated the country’s National Mammal on 9 May 2016 through the National Bison Legacy Act.
They literally go everywhere. When we walked through thermal areas, we often saw bison “patties” lying about.
When I asked a ranger how they could traverse the hot springs, she said that their hooves can withstand the heat; in some areas, their thick fur even shields them and they lie down to rest in the warmth for a while. However, rangers have seen some with burns on their legs.
Bison patties are also left in grasslands, hillsides and forests. I don’t recall seeing many on roads, however.
Most calves are born in late April and May. They can stand within an hour of birth and begin walking soon thereafter. It doesn’t take long at all for them to become rather independent even though their mothers care for them for about a year.
Apart from their obvious small size, the baby bison are notable for their reddish coloring; their fur will turn adult brown during their first mid-winter. When they are about 2 months of age, the characteristic shoulder humps begin to emerge.
The babies can be extremely playful; their relatively small size enables them to run and jump in seeming jubilance, leading to the nickname “red dogs”.
Perhaps it was the climatic circumstances, but we didn’t see as many playful red dogs as I’d seen in 2016. One youngster did give us a sample of youthful exuberance, however, running, jumping and generally exuding joy.
I did learn this year that Yellowstone’s bison are quite unique. The Park is the only place with bison that are direct descendants (without cattle genes) of the millions of early bison that roamed the area in prehistoric times.
By the late 1800s, only a few hundred bison remained, having been hunted to near-extinction and deprived of needed habitat. Then, by 1902, poachers had reduced Yellowstone’s herd to only about two dozen animals.
Today, their Yellowstone population varies from 2,300 to 5,500 animals and there are groups at other National Parks as well. The Native American Inter-Tribal Buffalo Council collaborates with the National Park Service to transfer bison from national parks to tribal lands.
It’s so fortunate that strides have been made in preserving these iconic animals for us to see in person. And dedicated people are providing resources for people who want to learn more about bison: https://allaboutbison.com/
