Yes, depending on the circumstances. There are several places you may visit, where you can see several species of toucans together mixing with other types of birds in free flight aviaries. Most notable of these facilities are the Matsue Vogel Park in Japan and the Dallas World Aquarium in Dallas, Texas.

The average toucan owner is likely to have only one toucan and maybe a couple other pet birds at home. Whether your birds are housed together in an aviary, or separately in individual cages within your home, toucans can and will get along with other birds if properly trained. This training is best accomplished with young birds. Toucans will sit peaceably next to other birds on perch stands and in adjacent cages. On occasion some minor conflict may arise, but training will resolve this issue. Large parrots such as macaws are potentially hazardous to other birds if they get close, so if toucans are mixing with macaws, be certain the macaws will not attempt to bite the toucan. A macaw bite can quickly remove toes and legs of other birds as well as damage beaks.

Whenever mixing birds together, whether it is toucans with toucans, or toucans with parrots, or parrots with parrots, always plan to spend considerable time observing the birds from a distance to be certain there will be no aggression. If aggression occurs, it is possible to eliminate it with training. Everything is possible with patience and perseverance.
