Parks Canada and the Canadian Wildlife Service have completed their joint whooping crane fledgling surveys on Wood Buffalo National Park and surrounding area. A total of 37 fledged chicks from 36 sets of parents were observed. An increase from last year’s 24 fledglings. It appears that conditions at the park were better than last year. May rainfall was only 84% of normal, however, in June rainfall was 141% above normal, with most (22mm) of that falling on June 2 just as some of the chicks were hatching.
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.
