When we first spotted this Fox Squirrel she appeared to be more lightly colored than what is the norm. The thought crossed my mind that she might be a rare “blonde” Fox Squirrel. On closer inspection, though, it became clear that the only thing unusual about this Fox Squirrel is that she is about halfway through with her seasonal molt. She is losing her winter fur as it is being replaced by her shorter summertime coat.
Reportedly, Fox Squirrels molt their fur twice a year. The spring molt takes place from head to tail, and the fall molt reverses direction and goes from tail to nose.
