FIGURE 5.

Eggshell thickness at the egg equator (model‐generated least squares mean ± 95% CI) did not relate to the status of the egg at the time of collection for three avian species (American avocet [Recurvirostra americana], black‐necked stilt [Himantopus mexicanus], and Forster's tern [Sterna forsteri]) during 2014–2018. Active eggs were normally progressing in nests that were actively being incubated, whereas abandoned eggs were from nests where the parents had naturally abandoned the nest. Eggs classified as dead contained dead embryos and had stopped progressing normally in nests while they were still being incubated and no sibling eggs in the clutch hatched. Failed‐to‐hatch eggs contained dead embryos and also did not hatch but were from nests where other sibling eggs in the clutch successfully hatched
