Lovebirds are playful parrots who are super active. They require a large living space where they can play all day. Lovebirds need their toys and perches with them all day in their home. Their nature is larger than life. But still, they need a large house to live in. The size of the entry hole should be about 3 inches in diameter. If you wish to keep a single lovebird, then the minimum size could be 18’’ tall, wide and long. These dimensions increase to 24’’ tall, wide and long for a pair of lovebirds. You can change these dimensions, depending on the available space.
