Should there be wildlife?

One of the things I liked about reaches campaign was the addition of wildlife. I think it added a nice feel tat we are on an actual planet and not some battle field. In Halo 4 do you think there should be more wild life? I think there should be more than just animals like the Moa. I would like it if there were some small animals and even birds that are flying. MAybe a few hostile ones like the Guta. I think it would be cool if we saw some of the covenant species that weren’t intelligent and more animal like.
