Black lories are known for their playfulness; they consider everything a toy. They can be comical birds; some like to wrap themselves up in a blanket for sleeping. They can even be seen sleeping on their backs. Black lories are popular as pets because they are so entertaining. Because they are very active birds, they need as large a cage as possible with plenty of toys to keep them occupied; they enjoy toys that can be taken apart. Although they engage in soft, high-pitched warbles and chattering, they also have shrill calls that can bother nearby neighbors. Black lories can be demanding in care requirements — with daily baths and special diet preparations — but their affectionate, playful nature endears them to those who own them as pets.
Although black lories are often affectionate, they can exhibit aggressive behavior, including biting, if their territory and/or possessions are not respected. This behavior can be redirected positively by understanding the bird's nature. Part of their diet should consist of good-quality nectar. Black lories have a tendency to squirt waste matter and, because their diets contain nectar, the liquid-like waste can make the surrounding area near the pet bird cage dirty. Easy-to-wipe surfaces near the cage, or aviary housing where they can fly and climb to their content and where waste can be easily washed off, are good housing options.
