Peach-faced lovebirds (Agapornis roseicollis) are one of the most common pet birds worldwide and the most popular of the lovebirds. These little birds are known as lovebirds because of the strong pair bond between mates that continually sit together preening, cooing, and billing. They are hardy and easy to care for. They are most commonly kept in pairs rather than as single birds and are ideal companion birds for people who prefer to watch the antics of a colorful lively pair of birds rather than a single bird. Their average lifespan is 15 to 20 years.
Canaries (Serinus canarius domesticus) require little space, are easy to keep, and are well-suited to almost any home environment. However, as with any bird, they require enough space to fly. One of the most endearing qualities of these birds is their beautiful songs. Males are the best singers — and they usually sing better when kept alone. Canaries make good pets for just about anyone, but they are especially appealing to older people. Canaries may live 20 to 25 years, with an average life span of 10 to 15 years.
Zebra finches (Poephila guttata) have become one of the most popular caged birds behind their competitors, budgies and canaries, but all three are close on the top 10 pet birds list. They are pretty, colorful, and fun, and make delightful pets. Although zebra finches are social, they are only social with other birds. They are shy around people and do not like to be petted or held. They should be kept in pairs and do even better in large groups. Since they mate for life, there should be an equal number of males and females. Zebra finches normally live for 5 to 9 years but may live as long as 12 years.
