    • Longevity records show that Upland Sandpipers are long-lived birds 

      Sandercock, Brett; Kramos, Greg (Journal article, 2020)
      The life-history traits of migratory waders are characterized by low reproductive rates, delayed maturity, and high survivorship (Myers et al. 1987, Sandercock 2003), which leads to low rates of maximum population growth. ...
