Animals that do well in urban areas tend to be the ones that learn to make use of resources such as the food humans throw away. But is our food actually good for them? A new study published in The Condor: Ornithological Applications suggests that a diet of human foods such as discarded cheeseburgers might be giving American Crows living in urban areas higher blood cholesterol levels than their rural cousins.

Every year, bald and golden eagles are killed when they inadvertently fly into wind turbine blades. One possible way to prevent these deaths is to chase the birds away with acoustic signals—sound. To determine what types of sounds are most effective in deterring the birds, researchers at the University of Minnesota and their colleagues tested the behavioral responses of bald eagles to a battery of both natural and synthetic acoustic stimuli.
