Bird as Omen?

As I type this, there is a bird sitting four feet from our front door switching between repose and watching intently. He has been there since before I came home and he did not move or try to flee when I walked right past him to go into the house. It's dark, so it's hard for me to guess the type, but he looks larger than a house finch, so I'm guessing he is a sparrow. He even allowed me to come back out of the house and visit with him. Is this an animal omen? I couldn't find much on sparrows, just crows, ravens and owls. If this is an omen, how should I interpret it? He's still hanging around on the porch.
