Endangered whooping cranes will soon begin their annual 2,400-mile spring migration from Aransas to Canada. As the rare birds leave the Lone Star State, Texas residents and visitors are invited to report whooper sightings.

Since beginning their slow recovery from a low of 16 birds in the 1940s, whoopers have wintered on the Texas coast on and near Aransas National Wildlife Refuge. Recently though, several groups of whooping cranes expanded their wintering areas to include other coastal areas and some inland sites in Central Texas. Last year, whooping cranes from an experimental flock in Louisiana spent most of their summer months in Texas, and the Whooper Watch volunteers were able to provide valuable information to TPWD, Louisiana Game and Fish and the United States Fish and Wildlife Service about these birds.
This year, biologists expect whooping cranes to start moving north in mid-March or early April. Reports to Texas Whooper Watch will also help improve the accuracy of surveys on the wintering grounds, as the growth of the flock has made traditional census methods more difficult.
Whoopers usually follow a migratory path through north and central Texas, including Wichita Falls, Fort Worth, Waco, Austin, and Victoria. During the migration they often pause overnight to use wetlands for roosting and agricultural fields for feeding, but seldom remain more than one night. The typical sighting (71 percent of all observations) is fewer than three birds, although the fall migration this year produced some groups of more than 10 birds. They may also be seen roosting and feeding with large flocks of the smaller sandhill crane. Whoopers are the tallest birds in North America, measuring nearly five feet tall. The cranes are solid white in color except for black wing-tips that are visible only in flight, red crown and black mustache. They fly with necks and legs outstretched.
Citizens can help by reporting sightings of whooping cranes and by preventing disturbance of cranes when they remain overnight at roosting and feeding locations. Sightings can be reported email@example.com or (512) 389-TXWW (8999). Observers are asked especially to note whether the cranes have colored bands on their legs. Volunteers interested in attending training sessions to become “Whooper Watchers” in order to collect more detailed data may also contact TPWD at firstname.lastname@example.org or 512-389-TXWW (8999).
