What type of New World monkeys (e.g., squirrel monkey, howler, sakis & titis, capuchin, tamarin & marmoset) would be the safest to keep in an aviary environment amongst birds? I know a lot of these species might have tendencies to predate eggs and even adult birds if given the chance, but I was just wondering what might be the best choice to avoid this happening, if such choice exists at all. The aviary in this scenario would be a large walkthrough hall of sorts, akin to Burgers' Bush or Masoala.
