Vancouver BC - Distinctive two tone whistle
by Doug Brown
I haven't spotted it yet. In the morning I hear this over and over: Two tone, each tone is almost a second long, with no warble, first tone is higher in pitch than the second.
Throaty, like the first tone is a drawn breath and the second is exhaled. Musically first tone could be a mid-A, then second descends to around a G.
I live in a wooded area, about 2km from the Pacific.
