I'm in the Baltimore area. Is it time to take down the hummingbird
feeder, or will they know when to head south even if that food is
available?

Hummers know exactly when it's time to depart the same as they know
exactly when to arrive. Keep feeding until at least two weeks after
you've last seen any. I'm up in NY, they're still here... they seem
to be feeding more on my roses, cone flowers, jade plant flowers and
others but they still sip that red juice. Why are you in such a
rush?!?!?
