I too had similar problems trying to shoot hummingbirds at a feeder on my porch. 1/180 of a second was way too slow to freeze their wing motion. I needed fill flash for the pop in their colors due to a backlit situation. eventuelly got frustrated without finding a solution. I had thought about setting up halogen worklights on stands to increase light levels, but didn't try it. Too bad they don't let you have a moron mode where the camera lets you do whatever you want without telling you you are a moron for even trying. I'm still not sure why i would care that my flash duration was longer than my shutter speed. Oh well, the hummers will be back again.
I agree that flash helps with hummers. However, wingbeat rate varies from 14-75 beats/second so a flash at 1/180th will provide freeze of wing motion.
