An Avian Dilemma — How Birds Are Hijacking Others’ Nests To Raise Their Young

A new study published in the Nature Connections journal looks at the particular phenomenon of brood parasites. These are birds that try to trick other birds into raising their eggs. They parasitize other nests by “squatting and dropping” their eggs there instead of using their own. Washington University assistant professor in biology Carlos Botero explains why birds do this in the first place and how it impacts Missouri’s ecology.
