From: Comparative egg attendance patterns of incubating polar petrels
Example plot showing a 1-day (22.9 h) period of egg neglect for snow petrel 13. Inset figures show zoomed images of egg cooling and rewarming. Measurements of time to cool or rewarm were determined by the elapsed time between the starting (circle) and ending points (square). Shown in each inset is the elapsed time and temperature change for each phase. Summarized data for all events recorded are shown in Table 2. The ambient air temperature over this 1-day period was 1.3 °C (min − 2.2 °C, max 3.0 °C)
