This is a sign of a bad theromstat,

Bad thermostat or a faulty pressure cap.

Could also be a head gasket leaking into the cooling system overpressuring the reservoir causing coolant loss.

how would you know the difference between the bad head gasket and a bad thermostat. I do not see any type of oily concatenation in the fluid. is it common for a thermostat to be bad on a 2007 with 104,000 miles. thanks so much for your help.
