Raptors is right ! I was gardening as always and heard a woosh overhead and saw a huge all white bird with brown just at the tip of his winged feathers maybe even larger than a Turkey Vulture which are pretty common here in San Diego. It landed up on my deck which I've never seen and than swoop down and grabbed a large rabbit or RoofRat in it's Talons. Sure would like to know what I saw since I've seen it twice more a couple of days apart.
