I have been up since 3, not so much by the mockingbird, but by the noise it otherwise generated at home, I can ignore a bird singing, even if it is a loud song. I have been considering strapping the baby monitor to the tree. It is a little device that plays a heartbeat when it hears the baby cry, hope the mocking bird sound triggers it, however it may have some sort of voice recognition and ignore that sound.
Finally invoiced my last client, I am now going to work on personal projects. However may consider engagements closer to home. Commuting 2 hours a day is out.
