The Indigo Bunting is a proud papa. As soon as the nest is built - a compact cup of grass and leaves, attached and standing in the upright crotch of a shrub - he starts proclaiming the blessed event from the treetops. He has even been known to take a turn on the eggs. His mate - what did he ever see in her? Dull and anonymous, she'd never be noticed in a crowd of sparrows. But he is faithful to the end - of the summer.
