The above bird is a Red avadavat, the bird below could be a female of this species but because of the bad position it is sitting in, not sure about that one.
obviously you can't see here but the head is all wrong for a Zebra Finch. I'm not sure about the bottom bird in this shot but thanks very much VC because I did actually see a female that I wasn't able to photograph, and I had thought it was a separate species that I would never get the ID for
