Description

In 2022, the federal government launched the second phase of the Oceans Protection Plan, a vast interdepartmental program designed to enhance marine safety in Canada by improving our ability to prevent and respond to marine incidents. For the Canadian Wildlife Service (CWS) of Environment and Climate Change Canada (ECCC), this means filling gaps in our knowledge of marine and coastal bird species. In order to identify these gaps for the province of Quebec, we carried out a prioritization exercise in 2022. We concluded that major efforts needed to be made in the Nunavik marine region, since data were lacking in several sectors and for several species. Understanding the vulnerability of wildlife species over time and space will help us, among other things, to assess risks and act quickly and appropriately in the event of incidents affecting the marine environment, such as an oil spill or shipwreck. Another important objective of the Oceans Protection Plan is to implement sustainable partnerships with the Inuit in order to share our respective knowledge of migratory birds, develop joint projects and support Inuit-led marine bird projects. It is in this context that aerial inventories aimed at identifying avian diversity, counting seabirds and coastal birds and better understanding their distribution at different times of the year have been taking place in Nunavik since 2023. These inventories are particularly aimed at sites of large gatherings, such as molting and staging areas, where birds are more vulnerable. During flights, the crew scans the sea, bays, river mouths and coasts for single birds or groups of birds. When birds are spotted, the number of individuals is estimated and a formal identification is made to the most precise taxonomic level possible, usually species or genus. In some cases, particularly for species that are more difficult to identify or in the case of very large groups, high-resolution photographs are taken to confirm identifications and estimates of the number of individuals a posteriori. Where possible, individuals are identified by age and sex. For the purposes of these inventories, flight-capable birds are considered adults unless immature plumage is easily identifiable from a moving aircraft. Thus, most ducks, as well as shorebirds, are considered adults as soon as they are able to fly. Occasionally, the aircraft lands on the ground for short periods to allow the team to refine the identification of the species, genus and age of the birds. These observations are then included in the database. Observations made over land, during various trips, are also recorded opportunistically.
