parent in the brute realm often have their oeuvre cut out for them , fromoctopus momswho ca n’t exhaust while looking after their eggs , to those animals going it alone . What is unusual is magnanimous mammals having multiple offspring , but that is exactly what ’s happened in Yellowstone National Park as a grizzly bear female person was spotted with an extremely rare five sonny .

Grizzly bears ( Ursus arctos horribilis ) are one of two species that populate within Yellowstone , the other being the black bear ( Ursus americanus ) . Bear cubs are normally born in January or February and typically in pairs though some litters can be up to four . This makes this litter of five even more unusual . In fact , it seems this is the first clock time a bedding that big has ever been report in the parking lot .

Andrea Baratte , a tour of duty scout at Yellowstone who grapple tofilm the cubs , toldCowboy State Dailyhe’d never try of a bedding of five before . “ I ’m so glad that I got to document it , otherwise nobody would have believed it , ” he said .

Nature photographerStan Millsalso film the sonny . “ These grizzlies were walking toward the right when I came over a little cumulation and discern them , ” Mills wrote in a subtitle in the video below ( the bear can be meet at 2:23 ) . “ The mother spotted me while I was getting my camera out . ”

There is the interrogative of whether the lad all belong to to the one bear mother or some have been adopted from another bedding . In 2011 , mother and daughter grownup bears each give birth to two and three cubs , respectively . The third cub originally belonging to the daughter waslater adoptedby the old bear . In 2016 , aKatmai brown bearadopted a yearling laddie in addition to her own 9 - month - sure-enough after its mother become flat . Grizzly bear mothers have been cognize to give up their cubs , possibly due to fright of man orhuman contact .

“ If this was truly a litter of five , it would be the first one commemorate in the story of the Greater Yellowstone Ecosystem , for trusted , ” read Frank van Manen , who lead the Interagency Grizzly Bear Study Team , in a affirmation inWyoFile .

Without transmitted testing , we wo n’t know if the currentYellowstonesupermom is biologically related to each of her offspring .

“ Five cubs in a bedding material are the most we have ever observed in the park , at least from 1959 to present — the period of the park ’s chronicle we have good records for , ” National Park Service spokeswoman Linda Veress told Cowboy State Daily .
