Got it finally! It has taken me 6 years to get a visual photo of this bird

We moved to this house six years ago and almost immediately we heard a very unique bird sing. My wife and daughter fell in love with its song. The only way I can describe it is Weee-Wooo. so as you can imagine that is what we call it. This is the best photo I have been able to get of it. Please help me identify it.
Thanks

Well Eric, my first thought when I looked at the photo was that it was a chickadee, but it is difficult to tell from the photo if it has any black on its throat. Your description of its song could fit for its slow long call. Lets see what our readers have to say.
