Hi I observed the male Harlequin Duck above the Falls on the small roosting island that they have preferred over the past few years. I found it after parking at Dufferin Islands and walking north to the wooden bridge behind the second pond. Regards Marcie Jacklin Directions: Take the 403 to the 420E exit towards Niagara Falls. Turn right onto Stanley Avenue/RR 102 to the Niagara Parkway.
