スミソニアン国立動物園さんのインスタグラム写真 - (スミソニアン国立動物園Instagram)「After an absence of more than 50 years, the swift fox has returned to the grasslands of the Fort Belknap Indian Reservation in Montana. The Assiniboine (Nakoda) and Gros Ventre (Aaniiih) Tribes of Fort Belknap released 27 swift foxes in collaboration with the Smithsonian Conservation Biology Institute, @DefendersOfWildlife and @world_wildlife, kickstarting a five-year swift fox reintroduction program. Data collected will increase our understanding of swift fox ecology and be a lesson for reintroductions of other small carnivores globally. To track movement post release, each swift fox was fitted with a GPS collar that will collect and transmit locations three times daily. The 57-gram collars, 3% of total swift fox body weight, feature a degradable screw and will drop off after approximately one year.
