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.

Wintering Whooping Crane Update, October 1, 2018

Wintering Whooping Crane Update, October 1, 2018
Wade Harrell, U.S. Whooping Crane Recovery Coordinator

Fall migration is upon us and we expect to have our first confirmed whooping crane in the area later this month! We have received a few unconfirmed reports of a few whooping cranes in Texas already, but have yet to receive a report with a photo or full description. If you have a question on whether the bird that you saw is a whooping crane or not, take a look here.  Many early fall observations of whooping cranes end up being American White Pelicans or Wood Storks, though both of these species usually arrive in Texas before whooping cranes and are often observed in larger flocks.

Cold and wet conditions early this summer contributed to a below-average breeding year in Wood Buffalo National Park (WBNP).  Eighty-seven nests were counted in May, producing an estimated 24 fledged whooping cranes (counted in August) that are now headed south on their first migration to Texas. It is likely that lower than normal chick survival was due in part to exposure to the wet, cold conditions. We know from historical records that we see a dip in chick recruitment and the population size about once a decade, and we may be witnessing that pattern again this year.

The Whooping Crane migration from Wood Buffalo to Aransas NWR is about 2,500 miles in length and can take as many as 50 days to complete. Right now, 9 of 11 of the whooping cranes that are alive from recent marking efforts in summer of 2017 and last winter have moved south out of WBNP and are in Central Saskatchewan. Three of these birds were marked as juveniles at WBNP and 6 were marked as adults here at Aransas NWR. It is common for whooping cranes to spend a long period of time in Saskatchewan this time of year, “staging” for fall migration by foraging on abundant agricultural waste grains. Our partners with the Canadian Wildlife Service are actively monitoring whooping cranes in Saskatchewan now and have reported seeing several of our marked birds.

We have not received any migration reports from the U.S. portion of the Central Flyway yet, nor have any reports surfaced via eBird, Texas Whooper Watch, or other citizen science sites. Thus, it is likely that few, if any, whooping cranes have crossed the 49th parallel just yet. Once northern cold fronts become stronger, the pace of migration will increase.

Texas Whooper Watch

Be sure to report any Texas migration sightings via Texas Whooper Watch. For instructions on how to report, please refer to this website.

Current conditions at Aransas NWR:

Food & Water Abundance:

September was definitely one for the record books, with at least 17.54” of rain reported at Aransas NWR. This is around half of our average annual rainfall, and as you can imagine it has created fresh conditions in the coastal marshes and standing water across large portions of the Refuge. Since June, we have recorded 36.19” of rain and the National Weather Service 3-month outlook suggests that the fall weather pattern will continue to be wetter and warmer than normal. Generally, wet periods bode well for whooping crane foods in the marsh such as blue crabs and wolfberries.

Habitat Management at Aransas:

We were able to burn one large unit (3,780 acres) on Matagorda Island on June 15. The area we burned consists of upland prairies adjacent to coastal marsh areas that are heavily used by whooping cranes. By maintaining coastal prairie habitats in a relatively open, brush-free condition, we provide additional foraging habitat that would not normally be available to the whooping cranes. Summer burns are typically more effective at suppressing brush species in our prairies than winter burns, and thus are an important habitat management tool at Aransas NWR.

Refuge Celebration October 13:

I hope you will come join us at Aransas NWR on Saturday, October 13, from 9 am to 3 pm for the annual Refuge Day Celebration and participate in a number of free, family-friendly activities that we have planned – archery, fishing, kayaking, target shooting, live animal displays, arts and crafts, nature journaling, photo scavenger hunt, face painting, and more!

2018 Whooping Crane Fall Migration Underway

Fall Migration Underway

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.

Nebraska reports

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 joel.jorgensen@nebraska.gov.

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.

Oklahoma reports

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 report

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: whoopingcranes@tpwd.state.tx.us 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.

Estimated Texas Wintering Whooping Crane Population Breaks 500

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.
