One to ovoid? Using 3-D printing, researchers can study what causes birds to reject eggs with greater precision and repeatability

For decades, researchers have been making artificial eggs out of plaster, wood, and other materials to test how birds identify and reject the eggs that invading ‘brood parasites’ sometimes sneak into their nests. But these methods have many limitations; a new study is the first to test the usefulness of 3-D printed eggs for research on egg rejection.
