Partners celebrating 50 years of whooping crane conservation

Parks Canada and its partners, Environment and Climate Change Canada (ECCC) and the U.S. Fish and Wildlife Service (USFWS), are celebrating 50 years of whooping crane conservation at Wood Buffalo National Park. This international conservation partnership began in 1966 when the fragile state of the world’s last whooping crane flock brought Canadian and American partners together to share their knowledge and work on joint species recovery efforts. This example of successful international stewardship is a model for cooperation amongst conservation groups in the preservation of endangered species that cross international borders.

Catherine McKenna, Minister of Environment and Climate Change and Parks Canada explained that: “The Government of Canada is committed to preserving our national parks and contributing to the recovery of species-at-risk. There is much to celebrate in the progress that has been made over the past 50 years in the recovery of this beautiful and iconic bird and I am very proud Canada’s role in this international conservation effort. I applaud Parks Canada and its partners, both domestically and in the US, for their on-going efforts to save this species-at-risk.”

FOTWW supports efforts of Wood Buffalo National Park

Friends of the Wild Whoopers (FOTWW) is one of several private groups that supports Wood Buffalo National Park and their efforts to protect and manage the only wild Whooping Crane flock on planet Earth. FOTWW joins with Wood Buffalo personnel, the U.S. Fish and Wildlife Service and others in celebrating the 50th Anniversary of outstanding Whooping Crane conservation. One highlight of the celebration is the hatching and survival of twin Whooping Crane chicks (Figure 1).

Accomplishments at Wood Buffalo National Park

The accomplishments of Whooping Crane conservation are remarkable. Mike Keizer, External Relations Manager, Wood Buffalo explained that, “We have watched the Wood Buffalo-Aransas Whooping Crane flock grow from 48 birds in 1966 to 329 today.  In fact, there are almost as many chicks born this year as there were cranes in existence when this partnership began and when annual surveys began in 1966. The 2016 chick count in August 2016 found that 45 chicks were born in 2016. 43 Whooping Crane pairs had one juvenile each and one pair had two juveniles. Annual productivity was 0.57 juveniles per nest, well above than the 20-year average of 0.48 but within the long-term natural range of variation (Figure 2).

Parks Canada and the International Whooping Crane Recovery Team

Parks Canada manages one of the finest and most extensive systems of protected natural and cultural heritage areas in the world, and is a recognized world leader in conservation.

Today, the International Whooping Crane Recovery Team oversees the cranes’ recovery. This group, made up of national, provincial, territorial, and state wildlife authorities and non-government organizations, works to preserve the ecological integrity of crane habitat, identify potential threats to the cranes, and foster research that builds a greater understanding of the species.

Aransas Wood Buffalo Population Update

Update on the Aransas Wood Buffalo Population of Whooping Cranes

The Unison Call – Vol. 27 No. 1

Breeding pair surveys in May detected 78 nests (an additional nest was inferred based on observation of a pair with offspring during August surveys), 15 of which were outside the area designated as critical habitat and seven of which were outside Wood Buffalo National Park; 18 pairs without nests were also observed. Surveys in August detected 45 juveniles; 43 pairs had one juvenile each and one pair had two juveniles. Annual productivity was 0.57 juveniles per nest, well above than the 20-year average of 0.48 but within the long-term natural range of variation.

The above are preliminary results from the Canadian Wildlife Service, contributed by Mark Bidwell.

Summary of Aransas Wood Buffalo Population Breeding Surveys for 2013-2016

Aransas Wood Buffalo

†Most nests ever recorded. *All family groups had a single offspring; **two families with twins; ***one family with twins; #20-year average is 0.48 chicks per nest. Wood Buffalo National Park (WBNP) 2013 data are from Harrell and Bidwell
(Oct. 2014), Report on Whooping Crane Recovery Activities; WBNP 2014 data are from Northern Journal (norj.ca), Sept. 1, 2014, quoting Mark Bidwell; WBNP 2015 data are from Bidwell and Conkin (March 2016), Recovery and Ecology of Whooping Cranes: Monitoring of the Aransas-Wood Buffalo Population during the Breeding Season 2015 Report. WBNP 2016 data are preliminary results from the Canadian Wildlife Service, with thanks to Mark Bidwell.

Aransas NWR winter counts are from ‘Whooping Crane Updates’ at the ANWR website. ‡Estimated numbers of birds outside the primary survey area in 2013, 2014, and 2015 were 6, 6, and 9, respectively. (95% CI means 95% confidence interval) — Ed.
