HOW DO NESTING BIRDS SUCH AS PIPING PLOVERS KEEP FROM BOILING THEIR EGGS IN A HEAT WAVE?

During this heat wave I have been concerned about one of the Piping Plover families that I am documenting. They are nesting in an exposed site and it is late in the season. I wondered if their eggs were at risk of becoming overheated. As of Saturday, my worries were for naught.

Both the Mom and Dad are sitting high on the nest. Typically when brooding eggs, Piping Plovers fluff out their brood feathers and the eggs are entirely hidden. During these 90-degree-plus days, the parents are continuing to sit on the nest to keep predators from seeing the eggs from overhead, but they are raising their bodies enough to allow air to flow beneath.

Both parents are struggling in the heat; they are overheated and panting while minding their nest, yet despite their obvious discomfort, they are determinedly continuing to brood.

Allowing for air circulation is really a pretty genius way of managing their eggs and I am keeping my hopes up that the pair will be successful ❤
