Hickory, a 1-year-old black-footed ferret, gave birth to her first litter on May 27. 💻 Tune in: Link in profile! *** Black-footed ferrets are endangered and presumed extinct until 1981 when a colony was discovered in Wyoming. Since 1988, our team has participated in U.S. Fish and Wildlife Service’s cooperative breeding and reintroduction program, helping increase the genetic diversity in the black-footed ferret population using artificial insemination and cryopreserved sperm. All black-footed ferrets today — in human care and in the wild — are descendants of the 18 individuals brought into human care to prevent the species from going extinct. 📸Photo: Black-footed ferret female Hickory standing inside a nest box as her kits snuggle up next to her.」6月2日 23時30分
