Jazz Bird in the Neighborhood

So today I got to mow the lawn! (Trying on the Timothy Leary “Life is an opportunity” approach to this chore.) I got to be outside in our BIG backyard. I got to walk, bend, push, lift and carry – all great functional exercise. I got to observe butterflies and birds gracefully fluttering around me. It was cool and overcast, so all in all an enjoyable experience.

AND —- I got a huge gift for doing this. As I was mowing the front yard, I kept hearing this bird call that sounded like the first four notes of a jazz standard that I like. Over and over, this bird sang this little intro and my brain voice would fill in the rest. I thought, “I need to go get my digital recorder and catch this sample. Ohhhh, but as soon as I do that, the bird will be gone.” So I continued mowing.

Later, while I was taking a hydration break in the house, I heard the bird again. I thought, “Dang, now is my opportunity.” I ran in my studio, grabbed the Zoom, went outside on the porch and captured this:

Isn’t that cool? I love that the bird is singing the beginning of…what is the song? I can’t identify it. It has a similar tonality to “My Blue Heaven”, but the melody pattern is not right for the beginning of that song. Here it is lined up the way it goes in the song. It repeats and then changes slightly the third phrase (of course, the bird did not change, so you are hearing just the first two iterations):

So I need your help. Can anyone tell me what song this bird is singing? Can anyone identify the bird? I never got a sighting on him either. Thanks for your input.
