Friends, this is a young hummingbird, probably a male, the black streaking under his chin is where the red gorget will become apparent after his winter molt.  There were two siblings fighting over the feeder near the visitor’s center yesterday and i sat for an hour, shooting their antics.  I like the tiny feet in this image and the tongue showing beyond his beak.  The tongue is not a straw but two fibers that collect nectar by capillary action, he can “lick”  the nectar from the source with a tongue that can move 13 times per second, wow fast, til Tomorrow MJ
