アメリカ自然史博物館さんのインスタグラム写真 - (アメリカ自然史博物館Instagram)「Let’s soar into the weekend with today’s Exhibit of the Day, the Museum’s Flying Bird Group! 🦩 This vintage photograph, snapped circa 1947, depicts preparators working on flamingos in flight. These migratory birds travel long distances, usually under the cover of darkness, sometimes flying up to 373 miles (600 km) in a single night. Though flamingos are known for their pink color, it isn’t something they’re born with. Flamingos feed on large quantities of algae and brine shrimp, which produce reddish pigments. When metabolized, they turn the birds’ feathers pink! Want to spot flamingos flying overhead? Join us at the Museum for Earthfest! Use “birdoculars” to make discoveries, hear from Museum scientists, and more! For details, link in our bio.
