Lovebirds are social birds and thrive in pairs or small flocks. Keeping only one lovebird as a pet can be challenging, as they require a lot of attention and social interaction to prevent loneliness and boredom. In the absence of a mate or companion, a single lovebird may become depressed, lethargic, or aggressive.
However, if you are willing to dedicate a significant amount of time and attention to your pet lovebird, keeping just one bird can be manageable. You will need to provide your lovebird with plenty of toys, social interaction, and mental stimulation. You should also consider spending several hours a day interacting with your lovebird, playing with it, and providing it with opportunities for exercise and exploration.
Ultimately, the decision to keep one or more lovebirds as pets depends on your ability to meet their social and emotional needs. If you are not able to provide enough social interaction or attention, it may be best to consider adopting a pair of lovebirds or another social bird species instead.
