Figure 4 in Nesting biology of the Spotted Nightingale-Thrush (Catharus dryas) and comparison of life histories in the genus Catharus

Figure 4. Daytime incubation behaviour in C. dryas. (a) Egg (black points) and environmental (grey points) temperatures, and the variation by hour measured as standard deviation. (b) Time on the nest, measured as the number of minutes in the nest. (c) Number of off-bout trips. (d) Length of off-bout trips. These figures are based on data from seven nest monitored during 52 days. This plot shows a relative constant pattern of egg temperature, nest attendance and the length of trips across the day.
