The low number of records and specimens of red foxes (Vulpes vulpes) for Arizona and Utah through the 1960s prompted us to collect verified records of the species from the Navajo Nation in northeastern Arizona and southeastern Utah. We compiled and verified 80 visual observations of 88 live and dead foxes, and 21 specimens, from the study area between 1979 and 2001. We also compiled 686 supplemental records of foxes reportedly trapped by permitted fur-trappers within the same area and time period. This work verified that the red fox was common to this region despite the low number of records prior to the 1960s and that northeastern Arizona should be included in distribution maps for the species. We analyzed temporal and spatial distributions of fox records and determined the vegetation types and elevational range of records within the study area. Numbers of trapped foxes (and trappers) peaked during the mid 1980s, but the number of observations has remained relatively constant. Foxes occupied a 1,100-m range of elevations and were observed in equal numbers in 3 vegetation types that comprise 95% of the study area. Seventeen of the 21 specimens were measured for 15 standard cranial measurements. A thorough literature review and museum search revealed 8 specimens previously documented elsewhere.
