Whooping cranes are passing through Nebraska for their annual migration, and wildlife officials are helping them by releasing more water into the Platte River at Grand Island.
The release will provide and maintain adequate roosting and feeding habitat for whooping cranes on the Platte River, and is expected to continue through early to mid-November when the whooping cranes leave the region.
The U.S. Fish and Wildlife Service plans to release water from their Environmental Account beginning on Oct. 19. The cranes use the Platte River in Nebraska as a stopover site during their migration in the Central Flyway south to Aransas National Wildlife Refuge, Texas for the winter.
Friends of the Wild Whoopers, (FOTWW) has received several reports and photographs of Whooping Cranes staging in Saskatchewan, Canada. On October 5th, a Whooping Crane was spotted and photographed at Quivira NWR, in Kansas. It can be said that the fall migration of the only natural wild population of whooping cranes is underway. The flock is expected to migrate through Nebraska, North Dakota and other states along the Central Flyway over the next several weeks. The Nebraska Game and Parks Commission, the North Dakota Game and Fish Department and other state Fish and Game agencies along the flyway encourage the public to report any whooping crane sightings.
If you see a whooping crane in Nebraska, please report your whooping crane sighting to Nebraska Game and Parks (402-471-0641), U.S. Fish and Wildlife Service (308-379-5562), or The Crane Trust’s Whooper Watch hotline (888-399-2824). Emails may be submitted to firstname.lastname@example.org.
North Dakota reports
If you see a whooping crane in North Dakota, please report your whooping crane sighting to, U.S. Fish and Wildlife Service offices at Lostwood, (701) 848-2466, or Long Lake, (701) 387-4397, national wildlife refuges; the state Game and Fish Department in Bismarck, (701) 328-6300, or to local game wardens across the state.
The Oklahoma Department of Wildlife Conservation is asking for your help in logging the migration path of the cranes. Sightings can be logged online here or by calling Endangered species biologist Matt Fullerton at 580-571-5820 or wildlife diversity biologist Mark Howery at 405-990-7259.
Texas Whooper Watch also has a project in I-Naturalist that is now fully functional. You can find it here. You can report sightings directly in I-Naturalist via your Smart Phone. This allows you to easily provide photo verification and your location. If you are not a smart phone app user, you can still report via email: email@example.com or phone: (512) 389-TXWW (8999). Please note that our primary interest is in reports from outside the core wintering range.
Keep your distance and why reporting is important
Should you see a whooping crane, please do not get close or disturb it. Keep your distance and make a note of date, time, location, and what the whooping crane is doing. If the whooping crane is wearing bands or a transmitter, please note the color(s) and what leg(s) the bands are on.
You may wonder why the wild life agencies are asking for these sightings to be reported. The reports are very helpful in gathering data and information on when and where the whooping cranes stopover, what type of habitat they are choosing, and how many there are.
With just over 500 wild whooping cranes migrating along the Central Flyway, odds are low of seeing a wild whooping crane. However, FOTWW hopes that someone reading this article will be one of the lucky few and if you are, please report your sighting so that these agencies and other conservation groups, including FOTWW can continue helping these magnificent cranes.

The numbers are in. This August, 24 whooping crane fledglings were counted in and around Wood Buffalo National Park.
Rhona Kindopp, manager of resource conservation with Parks Canada in Fort Smith, said while two dozen fledglings is a low number, “it’s still within the natural range of variation that we would expect from this species.”
Kindopp continued: “In some migratory bird species, productivity is influenced greatly by weather. This spring, in early June, we saw a significant increase in the amount of rain that we received locally.”
Kindopp stressed the weather may be just one contributing factor. “Another factor could have been local predation cycles. In other words, there may have been a greater number of predators in the area than in previous years,” she said.
Breeding pair surveys are done in mid to late May over 4-5 days with a crew of 2-3 made up of Parks Canada staff and Canadian Wildlife Service biologists. Breeding pairs normally use the same territory each year to build their nest and raise their chicks. Knowing where the cranes nest helps make locating the adults and juveniles a bit more successful. Following further examination of the data, this year there were 87 nests in and around Wood Buffalo National Park. Up one from the 86 nests that were originally reported in May.
The fledgling survey is done in between the end of July and mid-August. Fledglings are birds that have reached an age where they can fly. The technique for this survey is very similar to the breeding pair survey. The nest locations are known so that the staff can fly directly to the nest. If the Whooping Cranes have not been successful in raising a chick they may still be in their territory or they could be kilometers away. If a pair does have a chick, they are generally found fairly close to their nest.
Importance of surveys
Both the Nest and the Fledgling Surveys are part of the world-class restoration plan that has made the endangered Whooping Crane an international success story and symbol of species recovery and conservation. By counting the number of fledgling chicks, Parks Canada, Canadian Wildlife Service, US Fish and Wildlife Service, and others gain important insights into the health of the world’s last remaining natural nesting flock of Whooping Cranes that contribute greatly to our ongoing stewardship of these magnificent birds.
WBNP and nearby areas provide the last natural nesting habitat for the endangered Whooping Cranes. The birds are hatched in and near WBNP each spring. After they fledge they migrate 2,500 miles to their winter habitat on, or near the Aransas National Wildlife Refuge on the Texas coast. During their 2,500 mile migration they stopover 20 to 30 times to rest, forage for food and roost during the nights. Then, the following April the total population returns to WBNP to repeat the reproduction cycle again.
Estimated Texas Wintering Whooping Crane Population Breaks 500
Survey accuracy improved with shift from December to February timeframe
The first winter after Hurricane Harvey ravaged the Texas Gulf Coast, an estimated 505 whooping cranes arrived on their Texas wintering grounds after migrating 2,500 miles from their breeding grounds in Wood Buffalo National Park in Canada. Each fall the birds make their way back to Aransas National Wildlife Refuge and surrounding habitats, where they spend the winter. Once they have arrived, wildlife biologists with the U.S. Fish and Wildlife Service survey the birds by air and analyze population trends.
Biologists have completed analysis of aerial surveys of the Aransas-Wood Buffalo whooping crane population done last winter. A switch in aircraft the previous winter and a shift to surveying later in the winter when a larger proportion of the population had arrived helped improve accuracy of the counts. Preliminary data analysis indicated 505 whooping cranes, including 49 juveniles, in the primary survey area (approximately 153,950 acres) centered on Aransas National Wildlife Refuge near Austwell, Texas. An additional 21 birds were noted outside the primary survey area during the survey. This marks the 6th year in a row that the population has increased in size and the first time the population has topped the 500 mark.
“Breaking the 500 mark for this wild population is a huge milestone”, stated Amy Lueders, the Service’s Southwest Regional Director. “Seeing this iconic bird continue to expand demonstrates how the Endangered Species Act can help a species recover from the brink of extinction. I have to credit our biologists and our partners and local communities who continue to invest so much time and effort to improve our ability to make sure future generations have the chance to marvel at the beauty of these amazing wild birds.”
The U.S. Fish and Wildlife Service has implemented several small changes that have greatly improved the agency’s capacity to survey the birds. “After two years of testing a shift of our December survey timeframe to later in the winter, we believe our previous survey estimates were likely low given that not all the whooping cranes had completed migration by mid-December. We had indications of a later than expected fall migration over the last several years via migration reports and telemetry data. This is the first year that we have based our winter abundance estimate from a February survey timeframe rather than a December timeframe. It may seem like population numbers jumped more than usual, but in reality we are just capturing a more complete proportion of the population, with most birds having completed migration by early February” stated U.S. Fish and Wildlife Service Whooping Crane Coordinator Wade Harrell.
Harrell said biologists will continue to conduct flights in late January and early February for future surveys. He also stated that staff at Aransas National Wildlife Refuge continue to make progress in recovering from the impacts of Hurricane Harvey. “The good news is that the coastal marsh that supports our wintering whooping cranes was not significantly damaged by the hurricane and recovered quickly from any impacts, demonstrating how resilient intact wetland habitats can be.”
Whooping cranes are one of the rarest birds in North America and are highly endangered. Cranes have been documented to live more than 30 years in the wild. Adults generally reach reproductive age at four or five years, and then lay two eggs, usually rearing only one chick.
