Rain or shine, nature-loving Iowans are outdoors today, counting birds. The International Migratory Day is also known as the Big Count day and the “Bird-a-thon,” for some fans the most important day of the year. Ric Zarwell is head of Iowa’s “Important Bird Areas” program and an avid bird-counter himself. People will be out all day trying to spot different species and count total birds they see. Zarwell’s been working with Audubon Iowa for years and says a bird census can be as significant as the human kind.He says the data covers a wide area and long-time, helping show trends in bird populations. Zarwell says one example is a small warbler whose numbers dwindle as forest habitat disappears. The bird census is entirely voluntary and amateur, and anyone can go out and take part.
