Sparrow? ID in Richmond, VA (song attached) (1 Viewer)

Hi, hopefully the attachments work. Every day this bird sings the same song outside my office window all day long. He sings at the top of a very tall tree and I can't get a good look at him. I think it's a sparrow but once I saw him on a power line but my phone only got the attached silhouette which confused me even more because of the long non-sparrow looking tail. Does it sound familiar to anyone?

This is a Song Sparrow. They have a fair bit of variation in their song between birds, but this one is within the limits of "normal". It is very like them to sing pretty much all day, and they are a long-tailed species as sparrows go.

Agree with Song Sparrow.

Thank you guys so much!
