What is the exact locality within Maricopa County this photograph was taken? Living in Arizona now, Sigmodon arizonae cienegae is definitely a taxon I would be interested in seeing and photographing myself!
@UngulateNerd92 A few years ago I got very good closeup photos of a cotton rat at Sweetwater Wetlands, which is not that far from where you now live (and a LOT closer than Gilbert).
