The love bird is in fact a tiny parrot which originally came from Africa and Madagascar. Until that it, European explorers wrote about them in their journals. The explorers described the brightly coloured birds that they had seen on their travels and people wanted to know more about them.
The love birds were imported into Europe and became very popular as wedding gifts because of their loving ways and their passion to groom each other. The name love bird comes from their affectionate natures. They form very close bonds with their mates for the whole of their lives, which can be as long as 15 years.
