Urban raptor population assessment for the metropolitan Phoenix area, central Arizona, 2001-2006

Author(s):

  • Philip Tarrant, Global Institute of Sustainability, Arizona State University

Abstract:

The spread of urbanization is inevitable in both the developed and developing nations of the world. As cities continue to spread the impact on the environment, flora and fauna of their local ecosystems increases. In a southwestern U.S. city (Phoenix, AZ), we assess the effects of urban development on the local raptor population both in terms of casualties and nesting behavior.
