Ruby-throated Hummingbird - female

One of the first hummingbirds for the year, May 17, East Jordan NS. They seemed to arrive a little late this year, no doubt affected by the cold, wet Spring we had. At times there have been at least 4 birds attending the feeder in the weeks since, two males and two females. The males always seem to disappear once nesting starts, I haven't seen one in a week or more.  The last time one was doing his courtship ritual in the yard, flying pendulum style back and forth while being watched by the resident females or so I surmised.
