Happy Father’s Day! This month features the American goldfinch, one of the avian world’s busiest fathers. When brooding, a female goldfinch spends 95 percent of her time incubating eggs. She is totally reliant on the male for food. If there is a second brood, the father will assume the duties of feeding the fledglings, as well as the female.

Those who know the answers to all of these questions deserve a gold(finch) medal.
