"Birds perform important roles in the environment, for instance controlling pests by eating insects, scavenging and removing carrion, or eating fruits and dispersing the seeds. But only bird species that are well adapted to urban environments such as pigeons or crows can thrive."

"The homogenization—resulting from losing diversity through the exclusion of certain groups—of farmland bird communities may disrupt important ecosystem functions and services in urban agroecosystems such as pest removal by insect-eating birds," explains Professor Catrin Westphal, head of the Functional Agrobiodiversity group.
