| Video on Harlequin Ducks at Race Rocks. -by Kiprop |
A single male on the shore at Race Rocks. Look for them using the remote camera in the water down close to the island from the docks around to the West side. Ryan Murphy photo. |
The harlequin population shows up in late summer at Race Rocks and stays through the winter. They do not nest in the area,but go to northern inland lakes and rivers for that. Usually a group of 6 individuals is in the area. |
