Lovebirds are one of the smallest known parrot species. These beautiful little birds should not be overlooked in favor of larger, more demanding parrots; any Lovebird owner will tell you that these birds possess all the intelligence and personality of the largest of macaws. These birds are fairly quiet companions, making them ideal for those who live in apartments or condominiums. At around 6 inches long, the Lovebird has a life expectancy of up to 20 years.
