We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list the Sonoran Desert Area population of bald eagle (Haliaeetus leucocephalus) as threatened or endangered under the Endangered Species Act of 1973, as amended (Act). After review of the best available scientific and commercial information, we find that listing the Sonoran Desert Area population of bald eagle does not qualify as a distinct population segment (DPS) and listing the Sonoran Desert Area population of bald eagle is not warranted at this time.

Research like this is part of the relatively new field of urban ecology, the study of how urbanization affects interactions between the living and non-living components of a city. Thanks to a grant from the National Science Foundation, Phoenix - the fifth-largest city in the nation and still growing like mad amid a fragile desert ecosystem - is one of urban ecology's busiest study sites. Researchers here are discovering insights about urban ecology that they hope will apply to other cities in the West, and to arid urban areas around the globe. "I think we're providing a new range of information for people making decisions," says [Charles Redman], co-director of the project, "all the way from the individual house owner to homeowners' associations to town planners.

Real Animal" is to date both Escovedo's most straightforwardly autobiographical and the strongest synthesis of the singer- songwriter's many disparate musical impulses. If anything, Escovedo's desert twang is the least prominent musical direction featured on this album, subordinated to the volume and direct rhythms of his punk loves, which mark about half the album, and the carefully orchestrated melodies that fill the chamber pop of the other half. Escovedo enlisted Chuck Prophet to co-write the album, and it is produced by Tony Visconti, known for his work with David Bowie, T. Rex, and Thin Lizzy, and the punk and glam sensibilities Escovedo cultivates with his two collaborators are shot through the veins of the album like the "creature in (his) blood" of which Escovedo sings. Throug...
