The book "Avian Ecology and Conservation in an Urbanizing World" edited by John M. Marzluff, Reed Bowman, and Roarke Donnelly, provides a comprehensive overview of the ecological and conservation challenges faced by birds in urban environments. The book is divided into five sections, each addressing different aspects of avian ecology and conservation in urban settings. **Section 1** introduces the study of birds in urban environments, covering historical perspectives, the effects of urbanization on birds, synanthropic birds, human perception, and the quantification of urban gradients. **Section 2** explores processes affecting birds in urban environments, including population dynamics, community interactions, and the impacts of urban sprawl, non-native plants, and human disturbance. **Section 3** delves into specific bird populations in urban areas, such as Western Gulls, American Crows, Florida Scrub-Jays, and European Magpies, examining their responses to urbanization. **Section 4** focuses on bird communities in urban environments, discussing the homogenization of avifaunas, the role of greenspace reserves, and the conservation efforts in various urban regions. **Section 5** offers a synthesis of the book's main points, highlighting the need for long-term research, interdisciplinary approaches, and policy interventions to effectively conserve birds in urban areas. The book aims to provide a valuable resource for ecologists, land managers, wildlife managers, urban planners, and conservation biologists, offering insights into the ecological and conservation implications of urban life. It also includes high-altitude photographs of study areas, illustrating the diverse ways human settlement affects ecosystems.The book "Avian Ecology and Conservation in an Urbanizing World" edited by John M.
