In a plot line that could have been lifted from a Palin family drama, two high-profile grizzly mamas in Grand Teton National Park have performed a rare feat of bear behavior: a cub exchange.
Grizzly No. 399 has passed off one of her three cubs to grizzly No. 610, herself a daughter of the famous grandma. Grizzly 610 is rearing the adopted cub with her two offspring of the year.
At 15 years old, grandma griz apparently doesn’t have the energy to raise three young bears, the way she did in 2006-08 when 610 was a cub. The two bruin families have been occupying the same range — often along park roadways — since emerging from hibernation this year with their respective offspring.
