This is a magnified area of a photo, but I thought it told an entire story, so I am including it. I think the little bird is a female Sparrow.
As I admired this huge Yucca tree in full bloom, I noticed the little birds were flying in and out of its uppermost brances, and into the blooms. These tiny birds easily hid from my camera by moving to the other side of a bloom. I caught this little bird and zoomed in to find it taking Yucca blooms it had just picked for it’s nest! I assume the blooms are aromatic. A natural deordorizer for baby birdies not yet outof the nst. I mean, they don’t have diapers…. So NOW I understand why some of the blooms were missing!
