Harlequin Duck Infographic | Glacier National Park

In partnership with Glacier National Park Conservatory, I created an infographic documenting a scientific study conducted by Holli Holmes and Lisa Bate. Their research investigates the efficiency and accuracy of three non-invasive, survey methods to assess occupancy and/or abundance of Harlequin Ducks on streams in Glacier National Park. The three methods include camera traps environmental DNA (eDNA), and ground surveys.

Why is this project needed at this time?

Long-term bird monitoring programs throughout western North America have documented significant declines in bird numbers over the past five decades. Some of these species are common. Some are species of concern. Biologists are constantly challenged in their attempts to obtain solid data on the distribution, abundance, and reproductive success of all birds to protect them for the future.

"Western biologists have documented declines, and distribution shifts, of Harlequin Ducks (HADU), Barrow’s Goldeneyes (BAGO), and Great Blue Herons (GBHE) throughout their ranges. All are species of concern (SOC): species “at high risk because of very limited and/or potentially declining population numbers, range and/or habitat, making it vulnerable to global extinction or extirpation in the state.”
