Fig. 6From: Behavioural flexibility in an Arctic seabird using two distinct marine habitats to survive the energetic constraints of winterPredicted proportion of time diving (%) for thick-billed murres in winter, based on time of day (yellow = daylight, green = civil twilight, light blue = nautical twilight, dark blue = night), day of the year (DOY), habitat type (Cold or Warm), moon illumination (0 = new, 1 = full) and North Atlantic Oscillation (NAO) index. In the two upper plots, the solid line shows the mean prediction and shaded areas are the 95% confidence intervalBack to article page
