This morning our deck featured two squirrels, a cardinal, and what I assume were two bluebirds based on their color (every time I tried to get a picture, the birds would sense my movement through the window and fly away). Turning into a menagerie out there. The birds were a really beautiful deep blue color, though they looked bigger than what I found online when I did a search for "bluebird." Maybe they were blue jays. Noticeably bigger than the cardinal. I'm no expert on birds other than cleaning their crap off my cars, so I'm not sure what they were other than that I loved seeing the blue color.
