Here's a slo-mo video from earlier in the season. The hummer is feeding at rosebud salvia, but gets interrupted a couple of times by bees.
We still have at least a couple of hummingbirds around at the sanctuary, though activity is definitely tapering off, and I've greatly reduced the number of feeders. It will be interesting to see how much longer they stick around. However, it will be impossible to pin it down to an exact date, first because I'm spending less and less time at the sanctuary, and second because one can never be sure there are no longer infrequent visits. Often one can have a few days of no action, then they reappear for a couple of days (perhaps as laggards arrive from further north, and then scurry further south after a quick rest). Other reports indicate that there are still many sightings in the north of the country, though numbers are diminishing, and numbers on the Gulf Coast are climbing.
