Native to the Galápagos Islands, Nazca boobies nest in huge, crowded colonies, where adults frequently bite and peck their neighbors’ chicks. A Wake Forest University-led study shows that the birds more frequently abused as chicks are more likely to engage in such bullying as adults. Researchers are examining the role of early exposure to avian stress hormones in driving violent tendencies later in life.
