Overview: The population of Pintail ducks has been declining over the past decade, and wildlife biologists are trying to figure out why. Watch as captured hens are fitted with transmitters and tracked as they winter on the coast and migrate north. Examine how hurricanes have impacted Texas; past, present and future. In part two of a six part series on the state of the gulf, we'll see how a century ago a hurricane determined the future of Indianola and Galveston. Then take a look at how recent hurricanes, Rita and Ike, devastated Sea Rim and Galveston Island State Parks, and the progress of their recovery. We will reiterate the benefits of healthy marshland to diminish the force of hurricanes. Then visit oyster reef restoration sites in Galveston Bay and see how new technology is being used to map the bottom of Texas bays so that future damage from hurricanes can be more accurately assessed.
