Walnut— a crane at theSmithsonian’s National Zoo and Conservation Biology Institute, who chose one of the establishment’s workers as her mate — has died. She was 42.
The Washington, D.C.-based attraction announced Walnut’s death through anews releaseearlier this week.
“Staff at the Smithsonian’s National Zoo and Conservation Biology Institute’s (NZCBI) campus in Front Royal, Virginia, are mourning the loss of Walnut, a white-naped crane who became an internet sensation for choosing one of her keepers as her mate,” the zoo wrote.
According to the National Zoo, Walnut was considered “geriatric” for her species as she lived far past the normal life expectancy for white-naped cranes kept in human care. (The organization said 15 years is the average lifespan.)

Walnut was born in 1981 and was named after a local restaurant’s popular walnut pie, according to the National Zoo.
In 2004, when she was brought to NZCBI’s Virginia campus, Walnut formed a bond with keeper Chris Crowe, who artificially inseminated her after he mimicked how male white-naped cranes at the organization interacted amid their breeding season.
In the years to follow, Walnut went on to give birth to eight offspring, many of whom “reached adulthood,” per the zoo.
“Walnut was a unique individual with a vivacious personality,” Crowe said in a statement. “She was always confident in expressing herself, an eager and excellent dancer, and stoic in the face of life’s challenges. I’ll always be grateful for her bond with me."
