On a Facebook post I saw from Gus Keri, REDHEAD ducks still remain at the basin # 2 water reservoir.
I believe I have a map of the reservoir on my blog menu. ( If Not I will add it later)
look at the aerial view of the park below (The highway at the top border of the park is the Jackie Robinson Parkway. Nearest train is the J to Broadway Junction. See the blog "Save Ridgewood Reservoir".
