Friends, I call these wild Iris, the wild blues although when they have been out in the sun, they soon fade to a light blue or white.  This ruby-throated hummingbird was jumping from bloom to bloom.  He would periodically disappear into the willows and when he exited he flew above the iris in a u-shaped diving back and forth.  I witnessed a male showing off for his girl.   Although this shutter speed 1/1000 of a second is fast enough for most flying birds, hummers are too fast to freeze without special means. Their wing speed is 50 flaps/second and they do hum when they fly hence their name, hummingbird. til Tomorrow MJ
