The southern flying squirrel (Glaucomys volans), sometimes called the assapan or polatouche, is a species of squirrel in the family Sciuridae. G. volans is one of three species of flying squirrels found in North America. It is found in deciduous and mixed woods in the eastern half of North America, from southeastern Canada to Florida. Disjunct populations of this species have been recorded in the highlands of Mexico, Guatemala, and Honduras. There are 11 subspecies that are recognized as being valid, including the nominotypical subspecies.
Southern flying squirrels have grey-brown fur on top with darker flanks and are a cream colored underneath. They have large dark eyes and flattened tails. They have a furry membrane called a patagium that extends from the front to the rear legs and is used to glide through the air. Total length (including tail) is 21–26 cm (8.3–10.2 in). The tail can be 8–12 cm (3.1–4.7 in).
They are nocturnal and feed on fruits and nuts from trees such as red and white oak, hickory, and beech. They store food, especially acorns, for winter consumption. They also dine on insects, buds, mushrooms, mycorrhizal fungi, carrion, bird eggs... Wikipedia →

Under 5% of wildlife watchers report a Southern Flying Squirrel sighting in Houston on a given day, based on 15 verified sightings from GBIF citizen-science data. It is the 13th most-seen of the 17 mammals we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Southern Flying Squirrel in Houston on a given day, against under 5% in November to September, the lowest months.

GBIF citizen-science records
It is estimated from how often the Southern Flying Squirrel is recorded against all the mammals logged in Houston (15 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.
