Figure 3. Thermal images of a Black Skimmer (Rynchops niger) nest (12N, white rectangles) at Praia do Totelão, Pantanal, Mato Grosso, Brazil, taken on the same day (6 September 2015) in the early (05:59 h, A) and late morning (11.45 h, B), showing the mean (Ds), minimum, and maximum nest temperature, surface ground temperature (crosses), and egg surface temperature (within rectangles). Scale on right: color scale associated with the respective temperatures. With a special optical filter water drops were visualized (Blue and red circles outside the nest and next to the three clutch contours) which were taken to the nest by both adults. Note in Fig. B the sand surface temperature of 53.7℃. Photos by CO.BRA/INAU.
