Ibis - I only have hummingbirds in the Winter. I live in Sebastian, FL near Vero Beach. On rare occasions, I see a Ruby-throated hummingbird during the Summer months. (Always a female .... who might be a breeding female.)
There are breeding Ruby-throated hummingbirds (RTH) that nest in different areas of Florida in Spring & Summer in our state. In the southerly part of Central Florida as well as south Florida, the birds typically show up in Winter. I had 3 adult male RTHs spend the Winter with me last year and the year before. In 2011, I had 2 females and 1 immature male. The years in-between 2011- 2013, I had various males, but was not sure of the count. This year, I have 2 adult males so far and possibly another adult male that goes back and forth between my yard and the neighbor's yard. The birds aren't seen as frequently at the feeders until the weather turns much colder so that the plants are no longer blooming. Then the RTHs typically become "feeder" birds that I see regularly perching on the different feeders I have hanging around my yard.
So, YES! You may very well get hummers in Winter!
