Serum Biochemical Analytes and Trace Elements in Juvenile Whooping Cranes (Grus americana)

A comparative analysis of serum biochemical analytes and trace elements in juvenile Whooping Cranes (Grus americana) from Wood Buffalo National Park revealed significant differences between wild and captive populations, likely due to dietary variations. The study, conducted by Ratliff and Hartup (2019), sampled 31 wild juveniles aged 49–70 days during midsummer from 2010 to 2012, alongside archived serum and whole blood samples from captive cranes serving as age-matched controls. Reference values for serum biochemical analytes and trace elements were established in captive cranes reared under controlled conditions with known health histories. Statistical differences in blood biochemical profiles and trace element concentrations between wild and captive juveniles were identified, suggesting that dietary factors play a crucial role in the health of this endangered species. This research provides valuable insights into the nutritional and biochemical health of the only self-sustaining migratory population of Whooping Cranes in North America.
