Monk Parakeet, it took me a while to find the name, because I could not find “Quaker Parrot” (the name I was familiar with), in the index of Forshaw’s book. Actually several other species of South American parrot are well established as ferals in USA, and as Pete mentions rose-ringed parakeets are successful colonisers in many places. In Australia, so far we have not had much success of any foreign parrots even though we have foreign species kept as pets. Maybe because we already have so many native ones. Though some, such as Rainbow Lorikeet in south west Australia, have become successful within-country invaders.

Philip mentions mask parakeet as a stick nest builder (uniquely so) and I did wonder if this behaviour assisted in their invasion well outside their native range in Argentina (including the palms in wineries of Mendoza). But to counter, rose-ringed parakeets, equally invasive, are hollow nesters.

Joe Forshaw’s book does not appear to mention it, at least not in the introduction. Though he does mention Galahs using small leafy branches to line the nest hollow. (I happened to see this on Sunday morning.) Of peripheral relevance is that the lovebirds of Africa build a nest, as does this one (below extract from Wikipedia).



The monk parakeet (Myiopsitta monachus), also known as the Quaker parrot, is a species of true parrot in the family Psittacidae. It is a small, bright-green parrot with a greyish breast and greenish-yellow abdomen. Its average lifespan is 20–30 years. It originates from the temperate to subtropical areas of Argentina and the surrounding countries in South America


The monk parakeet is the only parrot that builds a stick nest, in a tree or on a man-made structure, rather than using a hole in a tree. This gregarious species often breeds colonially, building a single large nest with separate entrances for each pair. In the wild, the colonies can become quite large, with pairs occupying separate "apartments" in nests that can reach the size of a small automobile. These nests can attract many other tenants including birds of prey such as the spot-winged falconet (Spiziapteryx circumcincta), ducks such as the yellow-billed teal (Anas flavirostris), and even mammals. Their five to 12 white eggs hatch in about 24 days.

Do any Australian parrots or cockatoos build their own nest?
