Figure 5. Developmental stages of a Black Skimmer (Rynchops niger) clutch (nest 4S) at Praia doTotelão, Pantanal, Mato Grosso, Brazil, from July to September 2015, with three fertilized eggs revealed by thermal imaging (right); with maximum (Max), minimum (Min), and mean temperature (Ds) inside the nest (white outline). Stages: (A) Day 8, (B) Day 14, and (C) Day 18 (two days before hatching). Note the well-camouflaged eggs inside the nest depression exhibiting some variation in shell pattern (left), with narrow corrugations caused by adults' bills when relocating the eggs. Photos by CO.
