Humans have altered and created entirely new environments to which animals have either adapted or been extirpated. Urban environments are one of the most extreme examples of how humans have changed previous habitats. Urban environments present massive challenges for birds living in these spaces and the impacts can be seen on all aspects of their behavior including how they communicate with one another. This book discusses how seabirds and songbirds have adapted for life in urban areas, how it has impacted their migratory behavior, and also examines the ecology and conservation of these two species.
