If you put out the feeder they will come and you will have few , if it doesn’t get too cold for too long, in the fall and winter as it happened here. Lately we are having colder than usual winters but so far they survive.i'm so jealous you not only get hummingbirds, but get them all year! they migrate here and i never see many of them in the summer - often just once. but my daughter bought me a new, pretty all red glass feeder for christmas that i am excited to use in the spring, so maybe i'll get more this year.
I guess they shelter near chimneys. I noticed few times they were pretty dirty
