Scientific research for the conservation of the species
To conduct the corticosterone analysis on migratory bird species protected under the Migratory Birds Convention Act and the Species at Risk Act.
Start Date: 2015-11-05 End Date: 2019-03-15
Issuing Authority: Environment Canada
- Species at Risk Act
- Migratory Bird Convention Act
Location of Activity (province, territory or ocean):
(a) To conduct the corticosterone analysis, one must sample blood, a keratin-based tissue (e.g., feathers), or feces. Fecal sampling of Whooping Cranes would require following and/or temporary capturing the bird to allow for feces to be excreted and collected, which is more disturbance than can be justified ethically for Whooping Cranes. However, blood sampling is routinely performed by ICF on Whooping Cranes for health assessments (disease, blood chemistry, etc.), during which time feathers are collected non-invasively, so archived plasma and feather samples can provide retrospective measures of contamination and corticosterone over short-term and long-term periods, respectively. These archived tissues provide the only means of assessing past exposure to contaminants and measuring corticosterone levels. Thus to establish historical baseline levels – or reveal past exposure – these samples must be analyzed. (b) This research will use archived blood and feather samples (i.e., tissues collected previously) and therefore will have no negative impact on Whooping Cranes or their habitat or nests. Thus, no mitigation measures will be necessary. (c) This research uses previously-collected blood and feather samples and thus will not jeopardize the survival or recovery of Whooping Cranes.
