Researchers from multiple organizations are working together to track the population using GPS devices. The devices record 4-5 locations every 24 hours and help identify migration routes, habitat use, nesting areas and more. This great video from Texas Parks and Wildlife highlights the important work done and how it will benefit the endangered bird.Whooping Crane Tracking Study
The refuge posts Whooping Crane Updates while the cranes are on the Texas coast, their winter home. Get the most recent information on aerial surveys, habitat conditions and how the refuge is managing for the benefit of these endangered birds. While the Birds are Here

The Visitor Center is open Thursday through Sunday from 9:00 am to 4:00 pm. It is closed Monday, Tuesday, and Wednesday, as well as Thanksgiving and Christmas. The refuge auto tour and trails are open daily from 30 minutes before sunrise to 30 minutes after sunset.
The refuge uses Distance Sampling to estimate the population of whooping cranes within an established survey area. This survey method has been used to estimate populations of many other rare and endangered species, including fin whales, Karner butterflies and raptors. The refuge is not only interested in estimating the population within the survey area, it is also important to collect data on habitat conditions, food sources and other information that will lead to the best management decisions for the whooping cranes and other wildlife species.Counting the Birds
The average life span for an alligator that survives its first two years of life is about 50 years!
The Matagorda Island Unit of the Aransas National Wildlife Refuge is part of long chain of barrier islands that extend down the Texas coastline. This rugged landscape is host or home to many amazing wildlife species, including whooping cranes, Kemp's Ridley sea turtles, reddish egrets, alligators and coyotes.
