Yesterday I also posted the video of the hummingbird feeder swarm on the SW Birds site I belong to, also with the organic sugar info.  Virtually immediately I got a lot of feedback that organic sugar is high in iron, which can be lethal to hummers.  We did some research and discovered that was true.

  So despite the fact that the hummers seem to have done well in the past 18 months (when Steve arrived and switched over to organic) Terry emptied the feeders and refilled them with white sugar water.
