There are four main objectives of this project: 1. To survey Northern Fulmar (NOFU) nesting colonies in the Lancaster Sound region, at Prince Leopold Island (PLI), Cape Liddon (Devon Island), Hobhouse Inlet (Devon Island), Cape Vera (Devon Island), Baillarge Bay (Baffin Island), and Princess Charlotte Monument. 2. To assess plastic ingestion by seabirds, specifically NOFU and Thick-billed Murre (TBMU) at PLI. 3. To examine incorporation of plastic pollution in Black-legged Kittiwake (BLKI) nests at PLI. 4. To monitor contaminants in eggs of NOFU and TBMU at PLI. At the NOFU colonies, we will count and photograph the nesting areas from a helicopter. The helicopter will fly past the colony 250 m from the cliffs at about 30km/h. Multiple passes may be required, depending on the topography and the height of the cliffs. We expect to spend a maximum of a few hours at each colony. The purpose of the surveys are to count the birds present, so all measures will be taken to not disturb the birds. We take overlapping photographs that we stitch together afterwards with image software. We archive these and then mark each bird on a copy to conduct counts. Data are collated and stored with both Acadia University and federal wildlife officials. In 2018 the Canadian Wildlife Service and partners surveyed four NOFU colonies along the east coast of Baffin Island, and found that all of those colonies have declined by about 75% in the past four decades. Furthermore, genetic analysis of NOFU caught as bycatch in Baffin Bay fisheries indicates that about half of the individuals are from colonies in the Lancaster Sound region. We urgently need to assess whether population trends at colonies in the high Arctic, to help identify the geographic extent and cause(s) of the declines. These data will also aid management planning for PLI Migratory Bird Sanctuary, Nirjutiqarvik National Wildlife Area, and the newly formed Tallurutiup Imanga-Lancaster Sound National Marine Conservation Area. We also may land near each colony to salvage up to 10 carcasses or 10 eggs (birds found dead or cold eggs in abandoned nests) for each of the main species found at the colonies (possibly including NOFU, TBMU, BLKI, Glaucous Gulls, Black Guillemots, Common Eiders, Long-tailed Ducks, Snow Buntings, shorebirds). Samples from these birds will be used in ongoing analyses of contaminants and genetics. At PLI, a field crew will land to collect adults and eggs and take photographs. We will collect 40 adult NOFU and 40 adult TBMU. This will be done in an area of the colony away from any long-term population monitoring plots or egg collection plots. These birds will later be dissected to enable a detailed quantification of all ingested plastic pollution. Within established breeding observation plots for BLKI, 50 nests will be observed using binoculars to determine whether any plastic material is in the nest cups. Additionally, a minimum of 200 nests will be photographed (including the 50 nests within the focal plots) to be examined later for plastic pollution incorporation using digital photo processing software. While work of this type has not taken place in the Canadian Arctic to date, these methods are being used in Europe where BLKI are commonly found incorporating plastics in their nests. Finally, climbers will collect 15 NOFU eggs and 15 TBMU eggs, to be analyzed to track levels of contaminants in the marine environment (this contaminant monitoring has been ongoing at PLI since 1975). The work at PLI will be done in consultation and collaboration with the the Area-Co-Management Committee for the Migratory Bird Sanctuary, and the local hunter and trapper organization to ensure minimal impact on the land and animals during this work.
