Late start but I'm in. I wished I had seen this thread earlier. I am in a great area so I think I can catch right up. I'm starting today off with the first thing I saw ( and it was also a good omen ) outside my bedroom slider; an immature Golden Eagle. Therefore, so far today I have seen:

Golden Eagle
California Jay ( Scrub Jay )
Titmouse
English Sparrow
Linnet ( House Finch )
Lincoln Hummingbird
Ruby-throated Hummingbird
Redheaded (Acorn) Woodpecker
Redshafted Flicker
Common Crow
Raven
Towhee
Gold Crown Kinglet
Turkey
Domestic Chicken
Turkey Vulture

That's 16. Happy Hunting
