Figure 1
Number of active Willow Ptarmigan nests across the breeding season at a) La Pérouse Bay, Manitoba, and b) Chilkat Pass, British Columbia.Daily nest survival estimates from the top model at each site were used to correct for the number of nests that were likely active but failed prior to being found. The approximate size of the study area was 10 km2 for La Pérouse Bay and 4.5 km2 for Chilkat Pass. Note the different scales on the y-axes.
