We have this exact 30 ounce feeder in So. Calif and need to fill it every day (use 1 cup white sugar to 4 cups water.... http://www.hummingbirds.net/feeders.html#recipe ) and simply use a funnel to fill it with a 32 ounce Pyrex glass container.  I didn't want to get the model 220 because the clear reservoir is plastic...Glass is better for cleaning and maintaining.
