N: 1. love-bird, also lovebird, 1590s, small species of West African parrot, noted for the remarkable attention mating pairs pay to one another; figurative sense of “a lover” is attested from 1911.
2. I. Any of various small usually gray or green parrots (especially genus Agapornis of Africa) that show great affection for their mates. II. lovebirds plural, informal: people who are lovers: people who are in a romantic relationship.
3. Lovebird, any of nine species of small parrots, genus Agapornis (subfamily Psittacinae), of Africa and Madagascar. Lovebirds are noted for pretty colours and the seemingly affectionate proximity of pairs. (That one will die grieving if bereft of its mate is unproved.) The nine species are 10 to 16 cm (4 to 6 inches) long, chunky, and short-tailed; most have a red bill and prominent eye-ring. Sexes look alike. In the wild, large flocks forage in woods and scrublands for seeds and may damage crops.
4. Cultural Interrelation: We can mention The Birds (1963) directed by Alfred Hitchcock (1899-1980).
