The rosy-faced lovebird (Agapornis roseicollis), also known as the rosy-collared or peach-faced lovebird, is a species of lovebird native to arid regions in southwestern Africa such as the Namib Desert. A loud and constant chirper, these birds are very social animals and often congregate in small groups in the wild. They eat throughout the day and take frequent baths. Coloration can vary widely among populations. Plumage is identical in males and females. Lovebirds are renowned for their sleep position in which they sit side-by-side and turn their faces in towards each other. Also, females are well noted to tear raw materials into long strips, “twisty-tie” them onto their backs, and fly substantial distances back to make a nest. They are common in the pet industry, although lovebirds are often not hand-raised.
It inhabits dry, open country in southwest Africa. Its range extends from southwest Angola across most of Namibia to the lower Orange River valley in northwest South Africa. It lives up to 1,600 metres above sea-level in broad-leaved woodland, semi-desert, and mountainous areas. It is dependent on the presence of water sources and gathers around pools to drink.
Escapes from captivity are frequent in many parts of the world and feral birds dwell in metropolitan Phoenix, Arizona, where they live in a variety of habitats, both urban and rural. Some dwell in cacti and others have been known to frequent feeders in decent sized flocks. source
