Abstract
The Vancouver International Airport (YVR) is Canada’s second-busiest civil airport and is located on the Fraser River delta—the staging and wintering ground for millions of birds representing many taxonomic groups. Consequently, YVR experiences one of the highest bird-strike rates of any airport in Canada. Since 1994, LGL Limited has investigated and monitored avian ecology as it relates to existing and potential hazards to air-traffic safety at YVR. A formalized monitoring program is on-going. The distribution, abundance, and flight patterns of birds are recorded and summarized by individual species or by taxonomic group. Monthly and semiannual reports present information that depict changes in the local bird community regarding spatial, temporal, and behavioural factors. A multi-year database permits the comparison of these factors during a present period to past highs, lows, and averages. Data analyses are complex, but have been streamlined through the development and application of database programming developed specifically for this project. Using this, and other information such as habitat mapping and bird-strike statistics, “hazard maps” are generated. Together with the remainder of the reports, these maps provide the Wildlife Control Program with an objective view of bird hazards at YVR. Among other uses, this information can guide control efforts and gauge the effectiveness of bird control over time.
