17-year old harlequin duck identified in Glacier

By | June 6, 2013

A male harlequin duck, known to be at least 17 years-old, was recently identified in Glacier National Park by University of Montana researchers and Glacier National Park scientists. The banded duck is believed to be the third oldest on record. The oldest known banded harlequin duck has a recorded age of 18 years and 10 months. “Prior to these findings, harlequin ducks were reported to live up to only 10 years of age, which makes this finding a positive indicator of the health and longevity of harlequin breeding populations in Glacier National Park,” said Lisa Bate, Glacier National Park biological science technician. “Research indicates harlequin ducks mate for life unless something happens to one member of the pair. This old male has returned the last three years with the same female.”  Read the full news release from Glacier Park here.
