The NIH is 'largely finished' moving its former research chimps to a sanctuary

For two chimpanzees named Huey and Pancake, both in their mid-30s, this week has been unexpectedly dramatic.

Huey, a male, and Pancake, a female, have been devoted to each other for over two decades. Together, they got loaded onto a truck at a research facility in Texas, where they've lived since they were young. They traveled for hours to a place in Louisiana where the hoots of hundreds of chimpanzees echo over pine trees.

The two chimps are now hanging out in a building that serves as the welcome center for Chimp Haven, the largest chimpanzee sanctuary in the world and the official retirement home for research chimps owned or supported by the federal government.
