About this time of year for the last 3 years a little mama bird builds a nest above our front door, she builds it in my garland that goes around the door. It might have something to do with the lights that are in the garland, maybe it helps keep the baby eggs warm:)
I think it's amazing how the mama bird builds the nest with her little beak, i actually saw her build it this year. She would leave for awhile then come back with a mouth full of stuff and build away.
