Perfect Duluth Day

What is the dawn chorus of birds?

In the West Duluth area we get two choruses — a din of birds sing-talking. It’s annoying. It happens at dawn and also dusk. I am wondering if there is an expert who could tell me what type of bird this might be. I don’t have a recording, but it usually goes something like wa-oh wa-oh wa-oh twitter spike. The song is really varied with each “sentence” or “question.” It happens before the crows start their cawing craziness and the seagulls start piping up.
