WILDLIFE WATCHING — 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.
“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 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.”
Researchers launched the study in 2011, using radio-telemetry and banding to learn more about the location of harlequin nests and factors affecting offspring survival.
Upper McDonald Creek is considered an important breeding stream for harlequin ducks, comprising 25 percent of known broods produced in Montana. The area also has the highest density of breeding harlequins in the lower 48 states.
About 40 pairs of harlequins in the park are known to be in Glacier Park.
