Wild lovebirds don't appear to be choosy when picking a nesting place. It was discovered the strangest sites: under the eaves of huts, under the watering troughs of cattle, and even on the roof of an abandoned chicken coop. Peach-faced lovebirds have been found under gutters, on window sills, and in other niches of inhabited houses and other buildings. Lovebirds will also use abandoned bird nests, especially those of weaver birds. Most lovebirds nonetheless prefer proper hollows in the baobab and other trees.

The most accomplished architects of all the lovebird species are the Fischer's and the masked. Their accomplishments are exceeded only by the gigantic nest-building activity of Quaker or monk parakeet (Myopsitta monachus) from South America (which has been introduced to Puerto Rico and the Northeastern United States).

The two lovebird species can modify large openings and even large enclosures, which they fill with building material and adapt to their needs. Their nests always have two "rooms": a hall with entrance hole and a true breeding room, in which they lay their eggs and raise their young.
The speed at which lovebirds build their nests varies with the availability of suitable building material. They can finish in 10 to 14 days, but most of cases they took a month.
