Description

Lovebirds are in length, up to 24 cm in wingspan with 9 cm for a single wing and 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

Species

Species and subspecies:

Nesting

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.

Feral populations

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.Forshaw (2006). plate 45. 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.
