UPDATE: They are gone! I looked out the window yesterday a few times and never saw the momma bird but I assumed she was gathering food for the babies. Today I decided to walk out on the porch and look and the nest is empty. No signs of anything, no eggs, no pieces of shells and no babies. I don't know what happened! The nest is in a fern in a hanging basket under the roof of my front porch. Nothing looks disturbed so I can't figure it out. BOO HOO! This is the second nest of babies birds I've seen not make it this year. The other was at my Dad's house.
