The historical range of the ferruginous pygmy-owl included areas of southern Arizona, southern Texas extending south along both coasts in Mexico, through Central America into the southernmost population in Argentina. However, over the past 150 years urban and agricultural expansion within the United States has reduced its population to a few isolated pockets of uncertain stability.

Most of the owls until just the last couple of years have been found in residential areas in northwest Tucson. It take a lot of cooperation on the parts of private residents to help get the work done. These are incredible little birds that fill an interesting role in the environment since they are more diurnal versus nocturnal. Our objective is to gather as much information as fast as possible to feed into the process to make this County plan based on the best available science that we have.

Arizona is one of the most highly urbanized states in the nation with 87.5% of the population as of 1990 lives in an urban area. Corporate American views Tucson for tourism and mining. It is also known for aviation, missiles and aerospace; and for its astronomy and optics like Kitt Peak and Mt. Graham observatories. "Economic success will increasingly be determined by how effectively an area can spur technological innovation, entrepreneurship, education, specialized skills, and the transition of all organization -- public and private -- from bureaucratic hierarchies to learning networks."

Pima County contracted with Arizona Game and Fish Department to conduct telemetry analysis and gather information that would lead to effective conservation and recovery initiatives for the cactus ferruginous pygmy-owl. During 1997, banded birds were monitored. Beginning in 1998 and during 1999, pygmy-owls were radio-marked with backpack transmitters and followed on foot or by vehicle.
