About 5 p.m. one of the parents shows up on the ledge.  Hops along and then down onto nest area and picks up a "leftover" of the ground.
With about a minute chicklets go from "comatose pancake power nap mode" stampede on over and say "Hi, there Mom/Dad. What's that you got?". 
First one there swipes the leftover from Mom/Dad and tried to run off with it (a small repeat of last evenings performance).  Tug-a-war ensues with parent.  Parent wins and begins tearing apart the leftover and starts doling it out.  Doesn't last long though, it was only a small piece.  Parent flies off.
Within about two minutes, a parent (the same one?)comes back with a "real meal" and begins defeathering.  All three chicks are right there, in parent's face "feed me, feed me".Mom/Dad can't rip that bird apart fast enough for them.
By 5:15 pm this meal is over!
