Scientific research for the conservation of the species
This permit allows aerial surveys by fixed or rotary wing aircraft over the whooping crane summer range in and around Wood Buffalo National Park. Breeding pair surveys are May 1-30, hatching success surveys are June 5-20 and chick survival surveys are Aug. 8-20, 2006. The research also includes collection of unhatched eggs, scats and moulted feathers; measurement of nest ponds depth; collection of: water samples, potential food items of cranes, fecal pellets, prey remains, evidence of moulting, dead cranes and regurgitates. Crane vocalizations will be recorded on nesting territories by using playback to solicite reponses from territorial pairs. Live trapping of invertebrates, small mammals, amphibians, reptiles and minnows may take place on a limited basis. These activities have been conducted annually since 1966.

a) all reasonable alternatives to the activity that would reduce the impact on the species have been considered and the best solution has been adopted; Long-term population monitoring of the Whooping Cranes is necessary to make management decisions to assist with the recovery of the species. Least intrusive methods have been chosen to reduce or eliminate potential impacts to the Whooping Crane. Surveys of this nature have been conducted on the breeding and wintering grounds since 1966 and results to date do not indicate that there is any adverse impact. b) all feasible measures will be taken to minimize the impact of the activity on the species or its critical habitat or the residences of its individuals; and Aerial surveys are normally conducted from an altitude of about 300m agl. except lower passes may be required to determine colour leg band information and presence of chicks. No removal of surplus eggs is planned during 2006, unless the eggs are abandoned or in immediate danger of destruction (eg. fire or flood). In that case the eggs will be removed, determination of viability will take place and the eggs will be sent to the Calgary Zoo. Viable eggs will be hatched and nonviable eggs will go to Veterinary Pathology for analysis. Vocalizations will be recorded from a distance of several hundred metres so as not to overly disturb the birds on their territories. The researchers will land the helicopter away from the cranes and proceed on foot to within a recordable distance. All research will be directed and/or conducted by the principal investigator, who has several years of experience in the techniques involved. The procedures have undergone an animal care committee review. c) the activity will not jeopardize the survival or recovery of the species. There is no evidence to suggest that the aerial surveys, nest visits, collection of eggs, etc has had any negative effects on the population. From the time that the Canadian Wildlife Service begun the monitoring and recovery activities for whooping cranes (1954) the population has grown at an average rate of 4% per year.
