Hoothoot! I don't have an internal organ that marks the passage of time, but people could set their clocks by me. Some people do. My life isn't brilliant, but it IS highly structured, and whilst I'm relatively flexible, I have good habits: I go to bed and get up at pretty much the same time each day, etc.
Some people I speak to would also consider me wise, and have said as much several times, although I'm not sure I'd share that opinion. I'd say I was full of myself, because I have a lot of sage views, but...eh, semantics. My world view and manner of presentation in personal conversation gives the impression that I am relatively wise. How relative that is depends upon your perspective. Make of that what you will.
As an added bonus, Hoothoot is a bird, and I love birds.
