From macewan house (near the art gallery), head down the main path, to the double row of big spruces. Turn left at the end of the spruces. Continue along, past the start of the fence on the right, until you come to a trail though the fence. Right at the base of this hill, look a little left a few metres above eye level, where the nest is in the crook of a maple. It may take a while to see it!
