The trio will be on exhibit when Experience Migration opens in 2021. For now, our Bird House keepers are caring for them (and other amazing migratory birds) behind the scenes! #NZKW2019 Every year, sanderlings and ruddy turnstones make marvelous migrations—up to 12,000 miles round trip—between their breeding grounds in the arctic tundra and their wintering grounds throughout North, Central and South America. 🌑 That’s nearly twice the circumference of the moon (6,786 miles)!」7月28日 3時50分
