The Humming Birds have arrived again after an amazing journey of perhaps a 1000 miles on wings smaller than a thumb.  They have arrived at our feeders between May 1 and May 4 for 14 years in a row-as long as we have lived at our current place. We put our feeder out May 1 and the first male hummer arrived May 3 this year.  We mix 1 cup sugar with 4 cups of water, bring it to a boil, cool, and use that mixture as our food source. We do not add food coloring.  They are an amazing creature.
