Phase Shift

We are almost at the cusp point of a change in the flower-visiting habits of our hummingbirds.  I am seeing signs that the Columbine-Coral Honeysuckle phase is coming to an end (there are far fewer nectar-laden flowers on those plants) and that the Trumpet Vine phase is about to begin.  All of these plants are heavily dependent on the hummingbirds as pollinators and have evolved to respond well to hummingbirds.  In my own case I use Trumpet Vine as an indicator the complete set of summer residents is in place, rather than say only early birds or migrants.  Any day now there will be a phase change.  Can't wait!
