Anna's Hummingbird Fledglings

I believe the hummingbird chicks have achieved the stage of "fledgling" in that their flight feathers are ready to pop out of the sheaths.
They are increasingly active and have some new behaviors involving standing up and stretching their wings along with poking their tongues out.
It certainly seems like they are preparing for their launch party!
The Mom is looking thinner to me, but is still robust and bright-eyed.
