Flowers on a Sunday Morning

Like clockwork, it was another Sunday morning where the crows were gathered in the same general area for an extended conversation.  It's gotten so regular that I've decided to make Sunday morning at 9:30 am crow time, and be prepared with a recorder, some paper, a pen, and camera.  

When I pulled back the blinds I saw two crows strolling down the street.  A third one chose not to go and had its head and back facing me. I could see the wind turning up its feathers.  I got the impression that this crow was not a fan of the mighty winds that were blowing.

Before leaving, it tried to pluck a flower.  There's something about this little tree.  This is the third time I have witnessed a crow trying to pluck a flower from this tree, but they never can do it.

The crows concentrate on the bottom branch on the left side that hangs down very low. The crow stood next to the tree and tried get a flower from the branch that was near to the ground.  Once I saw two crows trying to pluck flowers from that same tree.  One stood on the ground next to it and concentrated on a flower near the ground.  Another one perched on the same branch but higher up and tried to pluck a flower. 

I've never in my life seen a crow try to pluck a flower before I came to this area.  Why do these crows want the flowers from this tree?  Do they actually eat them?  I've never heard of that before.  This warrants an  investigation.
