2022 Wood Buffalo Survey Results 96 Nests, 61 Colts

Each year, Canadian Wildlife Service (CWS) and Parks Canada staff conduct aerial surveys over the extensive wetlands of Wood Buffalo National Park, (WBNP) that the cranes nest in and call home for the summer. These surveys occur at the end of May for the purpose of locating nests and then again in late July to count the number of chicks fledged.

Parks Canada and CWS were in the air again this past Spring and late summer of 2022 searching for whooping crane nests and crane chicks amongst the extensive wetlands of the park. Water levels on the nesting territory were higher than normal for the 2022 whooping crane nesting season. However, park and wildlife officials were still able to observe 96 nests during their spring nesting survey. 13 of those nests were found outside of the boundary of WBNP and 26 nests were outside of existing identified critical habitat (range expansion).

During the summer, 61 colts were counted during the fledgling survey. Of the 61 counted, 11 families were observed having 2 colts. So if you see a higher number of “twins” wintering with their parents in Texas this year, you’ll know why.

CWS and Parks Canada cooperate to survey the Aransas Wood Buffalo breeding population. Annual monitoring of nests and fledgling numbers, estimates of the breeding population size and annual reproductive success, respectively, have been conducted in WBNP since 1966 via aerial surveys. Record numbers of nests (nearing 100) have been recorded in recent years. The long term 20-year average of fledgling survival is 0.49 fledglings per nest (so 2022 was a very good year compared to the average in terms of nest and fledgling success).

An estimated 543 whooping cranes wintered in Texas in winter 2021-2022

Population estimate shows continued signs of winter range expansion for the endangered bird

Last winter, an estimated 543 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 (Service) survey the birds by air and analyze population trends.

Record year

“It is exciting to see another record year as whooping cranes continue to increase in number and expand their winter range,” said Wade Harrell, the Service’s Whooping Crane Recovery Coordinator. “Next year, we will be adding the South San Jose Island and Heron Flats Secondary Survey areas to our Primary Survey area given we detected enough whooping crane groups there to meet our protocol for inclusion. Conserving additional winter habitat for the species will be a key component of future recovery efforts.”

Preliminary data analysis of aerial surveys of the Aransas-Wood Buffalo whooping crane population conducted last winter indicated 543 whooping cranes, including 31 juveniles, in the primary survey area (approximately 160,125 acres) centered on Aransas National Wildlife Refuge near Austwell, Texas. This is an increase with the last survey from winter 2019-2020 estimating 506 whooping cranes, indicating the population has grown over the last two years.

An additional 38 birds were recorded outside the primary survey area during the survey, which is also a record high. This marks the fifth year that the population has topped the 500 mark, although a survey was not conducted during winter 2020-2021 due to COVID-19 concerns.

Harrell said biologists plan to conduct the next survey in January 2023.

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.

Deaths of Endangered Whooping Cranes Under Investigation

Whooping Crane Deaths Under Investigation

The Oklahoma Department of Wildlife Conservation (ODWC) is working with the U.S. Fish and Wildlife Service (USFWS) to investigate the deaths of endangered whooping cranes near Tom Steed Lake in Kiowa County.

One whooping crane was discovered by hunters who notified game wardens with ODWC. The whooping crane subsequently died while being transported to a veterinarian clinic. Additional evidence was recovered at the scene. The USFWS’s Wildlife Forensics Laboratory conducted a necropsy and verified the cause of death as a shotgun wound.

Further investigation of the original crane’s location uncovered evidence of three additional whooping cranes, bringing the total loss to four. All of the deaths are being investigated by ODWC and USFWS law enforcement officers.

“This is sickening to see such a wanton waste of wildlife, and our Game Wardens are very eager to visit with the individual or individuals who committed this crime,” said Wade Farrar, Assistant Chief of Law Enforcement with the Wildlife Department. “Somebody out there knows something that will help in this investigation, and I trust that they will do the right thing and come forward.”

Whooping cranes are an endangered species with a total population of approximately 500 birds in North America. Whooping cranes are protected under the Migratory Bird Treaty Act and the Endangered Species Act. A conviction for killing a whooping crane can carry up to one year in prison and a $100,000 fine per person under the Endangered Species Act, and up to six months in jail and a $15,000 fine under the Migratory Bird Treaty Act.

Reward Offered for Information

Anyone with information regarding the deaths of these whooping cranes is asked to contact the Wildlife Department’s Operation Game Thief at (918) 331-5555 or the USFWS’ Office of Law Enforcement in Fort Worth, Texas, at (817) 334-5202. Callers with information may remain anonymous.

Operation Game Thief, the Oklahoma Game Warden Association, ODWC’s Wildlife Diversity Program and the USFWS are offering cash rewards for information leading to the conviction of the person or persons responsible for the death of these endangered cranes.

Whooping cranes travel through Oklahoma during migrations to and from their breeding grounds in Texas. Most whooping crane sightings in Oklahoma are reported from mid-October through November. Whooping crane sightings can be shared with the Wildlife Department online.

Record Year for Whooping Crane Nests at Wood Buffalo NP

It was a record year for the 2021 whooping crane nesting season at Wood Buffalo National Park, (WBNP). Park and wildlife officials were able to observe 102 nests during their spring nesting survey. In 2017, a total of 98 nests were observed on the nesting grounds. The 102 nests were found using traditional flights and at least 4 of the nests were found using the crowdsourcing techniques, Zooniverse. This satelite imagery once perfected could become important with the surveys in the future and as of now is proving to be helpful when used along with the standard aerial surveys.

Zooniverse crowdsourcing project.

The crowdsourcing project is continuing and still needs virtual volunteers from near and far to sign into Zooniverse and take part!  If you’ve not had a chance, take a few moments to sign on or share this link with others who might like to learn more and study the Whoopers from space!”  https://www.zooniverse.org/projects/whcr-cr/whooping-cranes/classify?reload=0&workflow=18333

Conditions at Wood Buffalo NP

For the most part, Parks Canada operations have returned to fairly normal levels, with COVID-19 mitigations such as physical distancing and masking still in place. Park staff have been able to operate campgrounds, interpretive programs and hikes, the Fort Smith visitor centre and all the usual resource conservation work that comes with Canada’s biggest national park.

Overall it’s been a good summer—with not much extreme weather other than a really bizarre one week stretch which this area and western Canada almost never ever experiences. It’s been the worst forest fire season on record in some places, but the WBNP area of the NWT has been relatively mellow and fortunate this summer.

Become involved with counting nests

Want to get involved and be a citizen scientist and help out the biologists? Just go to Zooniverse. Once there, you can register, do a tutorial and once that is done, you are ready to begin your own nesting survey. Who wouldn’t want to participate doing that!

Zooniverse is the world’s largest and most popular platform for people-powered research. This research is made possible by volunteers — more than a million people around the world who come together to assist professional researchers.
