Arizona shrew is one of the state’s genuine endemics, known from only a few isolated Sky Island ranges in the far southeast, and this dataset carries exactly one confirmed record, logged in April. That single point is not a measure of how rare the species truly is; it’s a measure of how seldom anyone traps or photographs a shrew this small in canyon-bottom leaf litter.
Because the record is this thin, no seasonal pattern or state-wide rank can honestly be drawn from it. The Arizona shrew’s real story is a narrow endemic range, not scarcity within that range.
