Making Momma Bird Mad

I went out this morning to check on the baby birds and Momma (or Poppa) caught me in the act of trying to take a picture.  I got dive bombed.  It was like being swarmed by a bunch of bees.  I got out of there and left them alone.  The chicks are hungry and need to be fed and I don't want the job so I will let the parents do it.
