3. Finches and CanariesFinches and Canaries are other popular types of pet birds. With most varieties measuring 5 inches or less, Finches and Canaries require less space than most other bird species. Unlike parrots, which are hookbills, Finches and Canaries are known as softbills or waxbills. These little birds thrive in small flocks, and generally pay little attention to humans -- making them perfect pets for those who love to watch birds, but would like a pet that requires minimal interaction. A well cared for Finch or Canary can live for up to 10 years.
4. LovebirdsLovebirds 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.
5. African GreysAfrican Greys have been said to be the most intelligent of birds, some boasting vocabularies of up to 2,000 words! Because these birds are so smart, they tend to be demanding pets, and will get bored quickly if not stimulated. If you are looking for a highly intelligent and affectionate friend, however, the African Grey may be right up your alley. Greys typically live 50-70 years.
