My babies and our 'Tweet Tweet'!!

While turning on the water to give our dry, yellow grass a drink Matt found a small bird's nest in a bush in our front yard. The nest has a five small eggs, some blue ones, and some pink ones! Anybody know anything about bird eggs?? What bird lays eggs that could be blue or pink?? This bird also likes to poop on our rear view mirrors on both our cars...just one side, but it poops a lot then smears it a little on the window...NASTY!
...And here are some pictures of my babies!
