After more than 20 months of pregnancy, Rose-Tu, a 30-year-old Asian elephant at the Oregon Zoo, gave birth to a beautiful calf on 1 February 2025.

Staff are keeping their distance to give the pair time to bond, but the calf appears to be a healthy, strong female, weighing in the vicinity of 200 pounds.

“We couldn’t be happier with how everything is going so far,” said Steve Lefave, who oversees the zoo’s elephant program. “This was one of the smoothest births I’ve ever seen. Rose knew just what to do. She helped her baby up right away. The kid was standing on her own within 15 minutes and took her first steps soon after that.”

Zoo staff had been on baby watch since 29 January 2025, when Rose-Tu’s progesterone levels dropped to near zero, indicating labor should begin soon. Rose experienced early labor throughout the day on Feb. 1 and began showing signs of active labor a little after 3 p.m.
Veterinary staff have yet to conduct their first check-up, but once Rose and her calf are ready, they’ll weigh the baby and confirm its sex. Based on their observations so far though, everything is going very well.

“Rose is a fantastic mom,” Lefave said. “She’s so gentle and protective, and the calf is already nursing well. These are signs that they will have a strong bond, which is exactly what we want to see. We’re ready to help if needed, but so far mom and baby are doing just fine on their own.”
It might take a little time before the new baby is ready for visitors, Lefave says, but once they’re feeling comfortable they’ll spend time in Forest Hall, where guests can catch a glimpse of the smallest member of the herd.

“We want to make sure the calf continues to do well and that Rose-Tu is calm and comfortable with people around,” Lefave said. “And we also want to give the baby a chance to bond with the rest of the elephant family.”

Considered highly endangered in their range countries, Asian elephants are threatened by habitat loss, conflict with humans and disease. It’s estimated that just 40,000 to 50,000 of them remain in fragmented populations from India to Borneo, and their home range overlaps with some of the most populous human areas on the planet — 20 per cent of people worldwide live in or next to Asian elephant habitat.
