Beak is too long and narrow for a sparrow and at least what I can see in your image seems to match the Pewee which would be part of the flycatcher family. The split tail would also match although it's hard to be positive from this angle. Looks to be singing its little heart out.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
