Table 4. Pearson correlation coefficients between western willets and marbled godwits seen during surveys, and nests found in the same areas, 1998–2000, in southeastern Alberta. For all survey periods, the number of sites where birds and nests were compared was four managed, three natural, three no wetland basin sites in 1999 and 2000, and four managed, two natural, and three no wetland basin sites in 1998. | |
