National Zoo Confirms Pregnancy of 12-Year-Old Asian Elephant, First Calf Expected in Nearly 25 Years

The zoo says the first-time mother is being closely monitored under an AZA breeding plan to bolster the endangered species.

Overview

  • Nhi Linh is due between mid-January and early March 2026 after breeding with 44-year-old bull Spike in April 2024.
  • Veterinarians are tracking the pregnancy with ultrasounds, hormone testing and behavioral checks, and report cautious optimism.
  • The pairing followed the Association of Zoos and Aquariums’ Species Survival Plan guidance to maintain genetic diversity.
  • Staff are preparing neonatal protocols and modifying the Elephant Trails habitat for a newborn, noting the risks and Spike’s prior calves did not survive.
  • Keepers say Nhi Linh’s mother, Trong Nhi, likely has a non-viable fetus but remains stable, and the zoo plans regular updates, an Elephant Cam and a $23 million fundraising push for elephant conservation and research.
