Three’s a rarity. Mom must have known she couldn’t raise them all and left them in a box. I smell a rat on this one.
Mom took the blanket out of the den and put it in the box for her cubs...good mom....
That struck me, too. Two is the normal litter for bears. I know a guy who killed a female bear in the early spring in northern Maine. (He was bear hunting and sat down to rest in a clearing, when a she-bear appeared on the other side of the clearing. She rose on her rear legs and began to roar, apparently intending to scare him. It worked. He shot her. Given her sex and the time of year, she probably left two cubs somewhere in the forest. Momma got a ride back to Massachusetts down the Maine Turnpike on the roof of an International Harvester 4WD small truck, to the horror and affliction of sensitive out-of-staters. This was before the days of the SUV. You had Jeep and you had IH.
First cub, "This box is too big."
Second cub, "This box is too small.
Third cub: "This box is just right."
I suspect the mother was likely killed by a poacher who couldn't bring himself to killing the cubs so he put them in the box hoping someone would find them......
At least she didn’t abort. There’s a service for this kind of thing in Chicago. It’s called Merciful Sisters of Ursus. You can drop cubs off for adoption, no questions asked.
