Some species of companion or caged birds are capable of serious violence toward other birds. In the world of parrots, large cockatoos, lovebirds and many members of the Poicephalus family (Meyer’s, Senegals, etc.) are especially noted for this level of aggression, though it has been seen in other species. In the world of wild birds, there are several species known for aggressive attacks on each other. Indeed, a well-known nature magazine had a wonderful article titled: “Hummingbirds: If They Were Large As Crows It Would Be Too Dangerous To Walk In The Forest!”
Be extremely cautious when putting birds together. Birds (songbirds as well as parrots) can be extremely territorial, so problems are especially likely if people try to introduce a new bird into an area in which another bird already lives. After all, most of us would resent a stranger being plunked without permission into our living room! The best technique to put two birds together entails getting a new, much larger enclosure in which to simultaneously introduce the two birds. See “Territorial” in this index for more information on this concept.
