PARAKEET
  I had several parakeets as a teen in L.A.  but it wasn't until I started learning about eggs that I learned that if a female starts laying eggs, she actually over produce and kill herself.  Calcium deficiency.  To defeat it you have to put phony eggs in with her until she gets "out of the mood"  Parakeets come in all kinds of colors and are really easy to maintain as pets.  It takes patience to teach them to talk and mimic, but they learn whistles all on there own.  I had one, Percy, that "fell in love" with my brother Warren, and that saved it's life.  They would whistle back and forth, and one summer day someone open the front door at the wrong moment and Percy flew right out side.  I hollared to my bro, "WHISTLE!"  And sure enough Percy whistled back from around the side of the house.  Warren put up his finger and Percy, willingly hopped on, and flew to his cage the minute we got in the house.  Didn't come out for several days.  Agoraphobic?   Wouldn't blame him.  I understand L.A. has flocks of exotic bird roaming the sky.  Escaped pets.  Not mine.  Thanks Warren.
