Lovebird is the common name for the genus Agapornis, a small group of parrots in the Old World parrot family Psittaculidae. Of the nine species in the genus, all are native to the African continent, with the grey-headed lovebird being native to the African island of Madagascar. Social and affectionate, the name comes from the parrots' strong, monogamous pair bonding and the long periods which paired birds spend sitting together. Lovebirds live in small flocks and eat fruit, vegetables, grasses, and seeds. Some species are kept as pets, and several coloured mutations have been selectively bred in aviculture. The average lifespan is 10 to 12 years.[1]
Description

Lovebirds are 13–17 cm (5–7 in) in length, up to 24 cm in wingspan with 9 cm for a single wing and 40–60 g (1+1⁄2–2 oz) in weight. They are among the smallest parrots, characterised by a stocky build, a short blunt tail, and a relatively large, sharp beak. Wildtype lovebirds are mostly green with a variety of colours on their upper body, depending on the species. The Fischer's lovebird, black-cheeked lovebird, and the masked lovebird have a prominent white ring around their eyes. Many colour mutant varieties have been produced by selective breeding of the species that are popular in aviculture.[citation needed] As of 2019[update], there are 30 known plumage colour variations among lovebirds, which are caused by pigments called psittacofulvins.[2][3]
Taxonomy
[edit]The genus Agapornis was described by the English naturalist Prideaux John Selby in 1836.[4] The name combines the Ancient Greek αγάπη agape meaning "love" and όρνις ornis meaning "bird".[5] The type species is the black-collared lovebird (Agapornis swindernianus),[6] which was originally placed into the genus Psittacus within a section called Psittacula by naturalist Heinrich Kuhl.[4] Selby contended that this placement rather than a separate genus was "artificial" and done "without regard to the structure, habits, or distribution of the species."[4]
The genus contains nine species of which five are monotypic and four are divided into subspecies. They are native to mainland Africa and the island of Madagascar. In the wild, the different species are separated geographically.[7]
Traditionally, lovebirds are divided into three groups:
- the sexually dimorphic species: Madagascar, Abyssinian, and red-headed lovebird
- the intermediate species: peach-faced lovebird
- the white-eye-ringed species: masked, Fischer's, Lilian's, and black-cheeked lovebirds
However, this division is not fully supported by phylogenetic studies, as the species of the dimorphic group are not grouped together in a single clade.

Nesting
[edit]Depending on the species of lovebird, the female will carry nesting material into the nest in various ways. The peach-faced lovebird, for example, tucks nesting material in the feathers of its rump.[10]
Feral populations
[edit]
Feral populations of Fischer's lovebirds and masked lovebirds live in cities of East Africa. There are interspecific hybrids that exist between these two species. The hybrid has a reddish-brown head and orange on upper chest, but otherwise resembles the masked lovebird.[11]
There are two feral colonies present in the Pretoria region (Silver Lakes, Faerie Glen and Centurion) in South Africa. They probably originated from birds that escaped from aviaries. They consist mostly of masked, black cheeked, Fischer and hybrid birds and vary in colours. White (not albino) and yellow as well as blue occur in many cases. The white ringed eyes are very prominent.[12]
Diet and health
[edit]
Parrot species (including cockatiels) are biologically vegetarian species.[13] Lovebirds forage for their food. In the wild, their diet mainly consists of seeds, grains, and leaves from trees, shrubs, and tall grass. [14]
Wild lovebirds may harbor diseases such as avian polyomavirus.[15]

General Description
Lovebirds, belonging to the genus Agapornis within the parrot family Psittacidae, are small, stocky birds characterized by a body length ranging from 13 to 18 cm and a weight of 40 to 60 g across the genus.[6] Their compact build features a short, blunt tail, which contributes to their agile, robust appearance suited to arboreal environments.[7] A prominent feature is their large, hooked beak, adapted for cracking seeds and nuts, a primary component of their diet, allowing them to efficiently process hard-shelled foods.[7] They possess strong zygodactyl feet, with two toes facing forward and two backward, which provide a powerful grip for perching on branches and climbing through vegetation, facilitating their movement in tree canopies.[7][8] In captivity, lovebirds typically live 10 to 15 years, though individuals can reach 15 to 20 years with appropriate care, including a balanced diet and veterinary attention; lifespan in the wild is generally shorter.[9][6]Plumage Variations
Lovebirds in the genus Agapornis exhibit a predominant green body plumage, derived from a combination of yellow psittacofulvin pigments and structural blue coloration influenced by melanin distribution, with species-specific accents aiding in identification. For instance, the peach-faced lovebird (Agapornis roseicollis) features a distinctive peach to orange-red coloration on the forehead and face, contrasting with its green body and blue rump.[3] Other species display unique markings, such as the orange-red forehead and cheeks of the Fischer's lovebird (Agapornis fischeri), the black face mask of the masked lovebird (Agapornis personatus), or the brown forehead of the black-cheeked lovebird (Agapornis nigrigenis), all set against a primarily green plumage.[10] These accents, including white eye-rings present in species like the masked, Fischer's, and black-cheeked lovebirds, play a key role in species identification and, in some cases, indicate subtle sexual dimorphism, though most lovebird species show minimal plumage differences between sexes.[11] Captive breeding has produced over 30 recognized plumage variations across domestic lovebird species as of 2019, expanding beyond natural greens to include blues, yellows, and whites through selective genetics.[12] Prominent examples include the lutino mutation, which eliminates melanin to yield bright yellow plumage with red or orange facial accents; the albino, a double recessive combining lutino and blue factors for pure white birds; and the pied mutation, featuring irregular white or yellow patches on a green or blue base.[12] These variations are primarily Mendelian traits, with the lutino mutation following recessive inheritance patterns, requiring homozygosity for the ino gene—autosomal recessive in species like Fischer's and Lilian's lovebirds, though sex-linked recessive in peach-faced lovebirds.[12][13] Recent evolutionary studies (2024–2025) highlight how parrot plumage colors, including those of lovebirds, arise from psittacofulvins—unique pigments biosynthesized via enzymes like ALDH3A2—for yellows and reds, overlaid with melanin for greens and structural interference for blues, enabling adaptive signaling in social and mating contexts.[14] This pigmentation system, distinct from carotenoid-based colors in other birds, underscores the convergent evolution of vibrant hues across parrot lineages, with mutations in key genes disrupting melanin or psittacofulvin production to mimic natural variations observed in captive lovebirds.[15]Taxonomy and Species
Classification
The genus Agapornis was introduced by the English naturalist Prideaux John Selby in 1836, with the name derived from the Ancient Greek agapē, meaning "love," and ornis, meaning "bird," reflecting the birds' affectionate pair-bonding behavior.[16] Lovebirds belong to the family Psittaculidae (Old World parrots) and the subfamily Agapornithinae, which also includes hanging parrots (Loriculus) and the guaiabero (Bolbopsittacus); the genus comprises nine extant species endemic to sub-Saharan Africa and Madagascar.[17][18] Historically, the species were classified into informal groups based on morphological and behavioral traits, particularly the presence or absence of a white eye-ring, as outlined in early ethological studies; eye-ring species such as Fischer's lovebird (A. fischeri) were contrasted with non-eye-ring species like the peach-faced lovebird (A. roseicollis).[2] These groupings emphasized differences in nesting behaviors and plumage, with eye-ring forms often considered more closely related due to shared traits like strip-carrying during nest-building.[19] However, modern phylogenomic analyses, based on genome-wide markers, reveal that such morphological divisions do not correspond to monophyletic clades; for instance, the peach-faced lovebird is positioned as ancestral to the eye-ring species in some reconstructions.[2][17] Phylogenetic studies indicate the ancestor of Agapornis colonized Africa from Australasia via trans-oceanic dispersal around 23 million years ago (95% confidence interval: 16.4–27.3 million years ago), with subsequent radiation across sub-Saharan Africa and Madagascar.[17][20] A 2025 phylogenomic study using full genomes from wild specimens confirms the nine extant species and their close relationships, with no taxonomic reclassifications.[18] Within the genus, species-level divergences span 0.7–10.8 million years, with the Madagascar-endemic grey-headed lovebird (A. canus) forming a basal clade sister to the black-collared lovebird (A. swindernianus), indicating early isolation of the island lineage.[17] This phylogeny underscores trans-oceanic dispersal events in the broader Psittaculidae radiation, but confines Agapornis diversification to African continental and insular contexts. Fossil evidence includes a new extinct species, A. longipes, from the Plio-Pleistocene of South Africa.[21] Subspecies are recognized in several Agapornis species to account for geographic and morphological variation; notably, the peach-faced lovebird (A. roseicollis) includes two subspecies—the nominate A. r. roseicollis, distributed in Namibia and northwestern South Africa, and A. r. catumbella from southwestern Angola, which differs in having a deeper pinkish-red face mask and paler overall plumage.[22]Species Overview
The genus Agapornis encompasses nine recognized species of lovebirds, small parrots endemic to sub-Saharan Africa and Madagascar, characterized by their compact size ranging from 13 cm to 17.5 cm in length and vibrant green plumage accented by species-specific markings.[18] These birds exhibit variations in bill color, facial rings, and collar patterns that distinguish them, with habitat preferences spanning arid savannas, woodlands, and highland forests.[23] As of 2025, most species are classified as Least Concern on the IUCN Red List, though several face threats from habitat loss and the pet trade, leading to Near Threatened or Vulnerable statuses for a few.[24] The following table summarizes the nine species, including scientific and common names, approximate adult lengths, key distinguishing features, primary habitat preferences, and current IUCN Red List statuses:| Common Name | Scientific Name | Length (cm) | Key Distinguishing Features | Habitat Preference | IUCN Status (2025) |
