Skull Valley resident Bob Pearson provided this information on wildlife:

I lived here starting 1940, when I was 5 years old. I attended local schools; I attended the University of Arizona following my 4 years in the Navy. I studied Electrical Engineering & then Wildlife Management, received BS in W/L Mgt plus some Graduate work at Utah State Univ.  in Wildlife Management.   My career was with the U.S. Fish & Wildlife Service, primarily in land management & public relations.  I had law enforcement responsibilities for the protection & conservation of all Migratory Bird species, including the Endangered American Bald Eagle ant the Threatened Golden Eagle. I retired as Refuge Manager of Benton Lake National Wildlife Refuge and The associated Wetland Management District (WMD).  The WMD covered a variety of habitats in North Central Montana, the District boundary included about 30% of the State.

Bald and Golden Eagles:

My records of both the Bald and Golden Eagle habitat use in this area of Western Yavapai County are scattered over a number of years.

Migratory birds, including the Eagles only occupy specific habitat sites for brief periods of time.  They have a moving Home Range.   Site usage by Eagles is dependent upon their food habits, the availability of that food source,  and the presence of Roost sites and or Nesting sites.  Predator pressure & or Human Disturbance factors also have great influence on site usage or avoidance.  Changing weather conditions affects the availability of food resources &  sheltered roost sites and is probably what triggered the Migratory tradition in birds. Most migratory birds thus have 1.) a wintering  Range  2.) a Summer Range . and then 3) the necessary essential Food & rest stops in between , twice a year (Migratory  lanes). Some birds use different routes going South than when going North.

The 320 acre BLM tract provides food & shelter & roost & or nest sites appropriate for the Golden Eagle.  Bald Eagles on the other hand are primarily dependent on Waterfowl & or Fish as a standard food source.  It is conceivable that Bald Eagles might perch & rest at some time on the BLM tract. My observations of Bald Eagles here are associated with small wetlands &  preferably  standing dead Cottonwood trees in the Skull Valley & Kirkland Areas.

Yellow-billed Cuckoo, and the Spotted Owl:

 In the early 1990's, I teamed up with 2 men from the Prescott Audubon Society and established a Nationally recognized "Christmas Bird Count" census area including parts of Skull Valley & Kirkland.  It was operated for several years.  I also have personal observational records of bird occurrence in this area, since 1989.

The Yellow-billed Cuckoo, and the Spotted Owl (photo record), also endangered species, occur in this area.  I have records of these two birds also.  I hear the Yellow-billed Cuckoo every year in this area, and the small wetland habitat on and near the BLM tract would qualify for it's habitat. I first got acquainted with it in Oklahoma & seven years later, I was able to immediately recognized it's call in the Refuge near Great Falls, Montana, without seeing it. I heard it from the office and went out into the shelter belt and got visual confirmation.  I have more immediate concern for these ladder two birds than I do for the former two.
