Long-Term Population Monitoring of Songbirds at Fort Liard, NWT May 2011 to September 2011 Main Investigator: Craig Machtans, Forest Bird Biologist, Canadian Wildlife Service Wildlife Research Permit Number: WL005034 LOCATION: Fort Liard, NWT. PARTNERS: Financial and logistical support was provided by: ´ ´ Canadian Wildlife Service, Environment Canada ´ ´ Aboriginal Affairs and Northern Development Canada (Fort Simpson office and Cumulative Impact Monitoring Program) ´ ´ Environment and Natural Resources (Fort Liard office). CONTACT: Craig Machtans, Forest Bird Biologist Canadian Wildlife Service, Environment Canada P.O. Box 2310 Yellowknife, NT X1A 2P7 (P) 867-669-4771 (F) 867-873-8185 (E) craig.machtans@ec.gc.ca RATIONALE: A crew from Canadian Wildlife Service (CWS) returned to Fort Liard, NWT in June 2011 to visit long-term sampling locations for counting songbirds. The work started in 1998 and is currently repeated once every three years (2014 is the next anticipated visit). The purpose of the current work is to document long term trends in songbird numbers in the region. OBJECTIVES: ´ ´ The objective of this project is to count birds repeatedly over time to detect any long-term changes to their numbers in the Fort Liard area. METHODS: A total of 513 bird counts were conducted at 258 unique locations. Each location is usually visited twice during June. Bird counts are ten minutes long and conducted between sunrise and 9 a.m. Plots are permanently marked. RESULTS AND MAIN CONCLUSIONS: We counted 5,971 birds from 79 bird species. Our complete dataset now contains over 48,000 records from the area. One new species for the region was heard in early June, a blue jay. We have recorded 187 species since 1998 over the course of all work and including incidental observations. A complex regression analysis that accounted for autocorrelation and observer effects was run on the data. Of 51 species analyzed, the summary is: Nineteen species had significant trends. Twelve species were increasing. Of those 12, six had poor statistical power so the result is questionable in spite of statistically significant results. Seven species were decreasing. Of those seven, one had poor power and is questionable. 18 2011 Annual Report of NWT Wildlife Research Permits
Wildlife Species Research: Birds Thirty-two species did not show any statistical trend. Twelve species had good statistical power so it is highly likely the result is correct. Seven species had moderate statistical power, so the result is likely correct (no increase or decrease). Thirteen had poor statistical power, so it is unclear until more data are collected what the population trend of these species are. Results are presented graphically in a companion document. The results are being integrated in a scientific paper to be submitted for peer-review and eventual publication in a scientific journal. LONG-TERM PLANS . AND RECOMMENDATIONS: Results from this project are used by Environment Canada to understand bird population health in Canada. The long-term plan for the project is to continue to revisit the sites once every three years. COMMUNITY INVOLVEMENT: This year we did not hire any community help. The tragic loss of elder William Betthale when we were just starting our field program prevented our normal assistant (Gerry Betthale) from helping us. Bay-breasted warbler. Photo: C.
