Wordless Wednesday - What type of birds are these? Parrots or Conures in the Toys R Us Parking lot?

I was at Toys R Us last week... And no, not for me, but my son. :) And as I was loading a new sand box for him, I heard several birds chirping, but they were not local birds to our area. We have sparrows, mocking birds, crows, robins, seagulls... But not this type of chirp. I felt like I was in the pet store. I turned to look, and there were 10-15 birds flying, swooping, playing... as if they have always done this.

So I am unsure what type of birds these are? Do you???

One last picture.

So they were flying all around this area of Sunnyvale CA. Kind of fun!
