From what I could see, they would all run around together and occasionally slow down to a walking pace. This is just one of the few photos I have where I got all three of them in the same shot, but it was really great to see them all so active and well-integrated.
From the photo, I would say the taller of the three is Elish. From your comments it would that Crackers has died, although I am suprised not to have read about it anywhere. Dawn would have been about 31 when she died. Whilst I agree with comments linked to the other photo that there are some easy improvements that could and should be made to the giraffe enclosure, I do think it is worth remembering that many of London's giraffe have lived long and, as I understand it, healthy lives in the enclosure, even before current modifications.
