Sampling comments: sampling was "from July 2000 to July 2004... in two 1 km x 1 km study areas in the goose colony at Karrak Lake and in two 1 km x 1 km study areas outside the colony" and sampling was only in "early to mid-July" each year
there were "three traplines" in each area and "Each trapline consisted of 25 trap-stations, spaced 10 m apart, and with one snap-trap within 1 m of each trap station... Traplines were set for two consecutive nights" and "baited with a mixture of peanut butter and rolled oats"; there was a total of "2744.5 trap-nights" because the authors "subtracted 0.5 trap-nights for each trap that was snapped without capture", so the actual total seems to have been 10 x 300 = 3000 trap-nights
