Every year, right on schedule, I get a big basket of flowers for Mother's Day and within a day or so of hanging them on the front porch, a bird promptly builds a nest in the flowers.
Which gives the kids a great view of the eggs as they hatch and the naked baby birds grow feathers and eventually fly away.
We've had several different types of birds build a nest in the basket over the years. One year - we even had a bird push the eggs out of the nest and lay her own eggs in the nest for the other bird to raise.
This year - purple finches have moved into the neighborhood.
