Jared - Not likely. I have banded late-season Ruby-throats that have thrived on sugar-water on the rocks. Similarly with late-season Rufuses, most notably one years ago in East Arlington, VT which drank nectar on the rocks well into January.
Feeders aside, Mother Nature's nectar in flowers can be a bit frosty at times, so not to worry.

Does anyone allow nectar to come to room temperature before feeding hummingbirds? I was thinking today that refrigerated nectar might reduce body temps, and on a cool day like today that might not be desirable (more calorically expensive). I make a quart at a time and refrigerate the excess. Curious if folks have thoughts abut this.
