Merriam's pocket gopher (Cratogeomys merriami) is a species of rodent in the family Geomyidae. It is endemic to Mexico, where it is found in the area of the Valley of Mexico and the Valley of Toluca at elevations from 1800 to 4000 m. Its favored habitats are the Zacatonal grassland and temperate pine-oak woodlands, as well as farmland and rangeland. Its karyotype has 2n = 36 and FN = 68.
Until 2005, what are now considered the separate species C. fulvescens and C. perotensis were included within this taxon. They were split off due to clear molecular, chromosomal and morphological differences. All three species are part of the C. castanops species group.
The species is named after American mammalogist Clinton Hart Merriam. Although its distribution is patchy, it is not thought to be threatened. Wikipedia →

With luck
About 10% of wildlife watchers report a Merriam's pocket gopher sighting in Mexico City on a given day, based on 139 verified sightings from GBIF citizen-science data. It is the 5th most-seen of the 19 mammals we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
Any time of year
In every month with enough records, about 10% of wildlife watchers report a Merriam's pocket gopher in Mexico City on a given day, so our monthly data shows no clear season.
Yes

GBIF citizen-science records
It is estimated from how often the Merriam's pocket gopher is recorded against all the mammals logged in Mexico City (139 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
