Now that more than half of the world’s population lives in cities, the study of birds in urban ecosystems has emerged at the forefront of ornithological research. An international team of leading researchers in urban bird ecology and conservation from across Europe and North America presents the state of this diverse field, addressing classic questions while proposing new directions for further study. Areas of particular focus include the processes underlying patterns of species shifts along urban-rural gradients, the demography of urban birds and the role of citizen science, and human-avian interaction in urban areas. This important reference fills a crucial need for scientists, planners, and managers of urban spaces and all those interested in the study and conservation of birds in the world’s expanding metropolises.















the land use classes where each public sighting of roadrunners occurred (used) with the amount of that class based on the WHIPS database (available). We calculated the total area for each land use class and then calculated the expected number of points that would fall in each land use class if use was consistent with availability. We then used chisquare goodness-of-fit tests (Sokal and Rohlf 1995) NO. 45 Lepczyk and Warren to compare observed use of land use classes by roadrunners to an

In two field tests of bird identification involving six species and 40 residents of Tucson, only the roadrunner was identified correctly 100% of the time (Webster and DeStefano 2004). The Gambel’s Quail (Callipepla gambelii) and Rock Dove or Pigeon (Columba livia), two very common species in Tucson, were identified correctly

natural areas remaining at the edge of the city. Beyond describing how birds are distributed within Tucson, further analyses of the TBC distribution data indicate how birds respond to different habitat features and land uses in urban areas. Turner (2003) used a single year of RP data to quickly assay the sensitivity of more than 70 species to development. Results indicated that a suite of native species are particularly vulnerable to development and merit greater attention 144 STUDIES IN AVIAN

maintaining bird populations within the Tucson area. Due to the scarcity of natural habitats and permanent bodies of water in developed Tucson, the RP, with its comparatively coarse resolution of ϳ1 km between sites, misses many of these locations. The finer spatial and temporal resolution of the PMP complements the design of the more extensive RP. Another benefit of the flexibility in locating PMP sites is that it has enabled the TBC to form partnerships with several other organizations that use
