Wading Birds: Am I Heron You Right?
While schools are closed, we're creating a series of "Talk of Iowa" episodes that will be fun and educational for learners of all ages. Every Tuesday, we'll learn about Iowa wildlife, and every Thursday, we'll learn about Iowa history.
Unlike our neighboring state to the north, Iowa isn’t famous for lakes, rivers and streams, but our wetlands and waterways do attract some spectacular birds. Wildlife biologist Jim Pease will introduce listeners to the wading birds of Iowa’s wetlands.
We’ll learn about great blue herons, great egrets, snowy egrets, sandhill cranes, green herons and spotted sandpipers. We’ll discover what makes these birds unique, including their striking calls. We’ll also talk about colonial nesting behavior and the advantages it provides. Several of these species were once hunted to the brink of extinction, fortunately we still have the opportunity to see them today. Pease will give listeners some tips on how to get outside and see and hear these birds in person.
