In December, we were in a value studio across from where you indicated. We saw tommies(?) (small group of 5-8), saw and heard the crazy bird and watched an ostrich. I did see a zebra, far off to the left, toward Kidani construction, in the morning. There was a giraffe feeding station, or what looked like one, by our balcony, but it wasn't used.
We have visited AKL to see the animals, even when we haven't stayed there, and I have seen lots of animals from the observation room. Since you look at the Sunset Savannah from that room, I don't think they have far fewer animals there by design, but I too, was disappointed in the number of animals that I saw from our room in December. However, I also walked around the pool area, by the flamingos, and saw significantly fewer animals around that area as well.
